93x Man 531370-1 A - vs4.qxd 2/18/2005 11:11 AM Page 6 900 SERIES" INTRODUCTION Your 900 Series Ultra Wide Screen Fishing System comes in several different configurations. See the following list of products, all of which are covered by this manual, to find your 900 Series" configuration: NOTE: Only 937 DF Combo and 937c Combo models come with GPS and builtin cartography, + Humminbird® 931c: Ultra Wide Screen Fishing System with Single Frequency 200 kHz Transducer, optional GPS support + Humminbird® 931 DF: Ultra Wide Screen Fishing System with Dual Frequency 200 kHz and 50 kHz Transducer, optional GPS support + Humminbird® 937c Combo: Ultra Wide Screen Fishing System with Chartplotter (Maps) and Single Frequency 200 kHz Transducer, GPS Receiver included + Humminbird® 937c DF Combo: Ultra Wide Screen Fishing System with Chartplotter (Maps) and Dual Frequency 200 kHz and 50 kHz Transducer, GPS Receiver included.

HOW THE 900 SERIES" WORKS

Sonar technology is based on sound waves. The 900 Series“ Fishing System uses sonar to locate and define structure, bottom contour and composition, as well as depth directly below the transducer. Your 900 Series" Fishing System sends a sound wave signal and determines distance by measuring the time between the transmission of the sound wave and when the sound wave is reflected off of an object; it then uses the reflected signal to interpret location, size, and composition of an object. Sonar is very fast. À sound wave can travel from the surface to a depth of 240 ft (70 m) and back again in less than % of a second. It is unlikely that your boat can outrun" this sonar signal.

= 229 SINGLE BEAM SONAR

F4 = _— Your 900 Series" 937c Combo and 931c use a 200 kHz single Î beam sonar system with a 20° area of coverage. Depth capability is affected by such factors as boat speed, wave action, bottom hardness, water conditions and transducer installation. NOTE: The 937c Combo and 931c model use single bear transducers, but may be upgraded to dual beam functionalty with the purchase and installation of a dual beam transducer Contact our Customer Resource Center at either 1800-633:1468 or visit our website at wwihumminbird.com for more information. NOTE: Your Single frequency (937< Combo or 931c model) 900 Series" unit was shipped from the factory with a Dual frequency software configuration. Before trying to operate our unit, you will need to set your 900 Series" to Single Beam in order for it to work proper) See Sonar Menu Tab: Transducer Select for more information.

DUALBEAM PLUS" SONAR

Your 900 Series" 937c DF Combo and 931c DF are shipped with a 200/50 kHz DualBeam PLUS" sonar system with a = \vide (74°) area of coverage. DualBeam PLUS" sonar returns can be blended together, viewed separately or compared side-by-side. DualBeam PLUS" is ideal for a wide range of conditions - from shallow to very deep water, in both fresh and salt water. Depth capability is affected by such factors as boat speed, wave action, bottom hardness, water conditions and transducer installation.

93x Man _531370-1 A - vs4.qxd 2/18/2005 11:11 AM Page 7 À GPS AND CARTOGRAPHY {with 937c DF Combo and 937c Combo models only) The 937c DF Combo and 937c Combo models use GPS and sonar to determine your position, display it on a grid, and provide detailed underwater information. The Global Positioning System (GPS) is a satellite navigation system designed and maintained by the US. Department of Defense. GPS was originally intended for military use; however, civilians may also take advantage of its highly accurate position capabilities, typically within +/-10 meters, depending on conditions. This means that 95% of the time, the GPS receiver will read a location within 10 meters of your actual position. The GPS Receiver also uses information from WAAS (the Wide Area Augmentation System), EGNOS (the European Geostationary Navigation Overlay Service), and MSAS (the MTSAT Satellite Augmentation System) satellites if they are available in your area. GPS uses a constellation of satellites that continually send radio signals to the earth. Your present position is determined by receiving signals from up to 12 satellites and measuring the distance from the satellites. The GPS Receiver, when attached to your 937c DF Combo or 937c Combo model, allows you to combine easy-to-use FishingGPS"* chartplotter and navigation capabilities with advanced fishfinding. The following GPS functionality is currently supported by the 937c DF Combo and 937c Combo models when it is connected to a GPS Receiver: +_ View current position +_ View current track (breadcrumb trail) + View precision speed and heading from your GPS receiver + Save tracks, waypoints and routes + Travel a route and navigate from one waypoint to the next. NOTE: Only the 937c DF Combo and 937 Combo models support Navionics® Gold Charts marine cartography and Navionics® HotMaps" 2004 Gold for inland fishing. The 900 Series" does not support Navionics® Classic Charts. The 937c DF Combo and 937c Combo models also come with a builtin World map with a more detailed map of North America (Domestic models) or a more detailed map of Europe and Southeast Asia, including Australia and New Zealand (International models). Your 937c DF Combo and 937c Combo models use the GPS Receiver to determine the position of the boat automatically, and uses the zoom level settings on a particular view to select the best chart to display. See Viewing Cartography for more information.

MULTI-MEDIA CARD (MMC)/SD SLOT

The 900 Series" 937c DF Combo and 937c Combo models support cartography, and have two mult-media card {MMC)/SD slots. Optional-purchase MMC and/or SD cards can contain additional detailed maps. You can also export navigation data from your unit onto an MMC/SD card (see Navigation Main Menu: Export All Nav Data). ff you insert an MMC or SD card that contains a more detailed chart for a particular location, your unit will retrieve that chart and display it automatically. 931c DF and 931c models have one MMC/SD slot and do not support cartography. Multi-Media Card {MMC/SD) Slot On any model, use the MMC/SD cards to update the software version of your control head. To update the software in your control head, plug in the appropriate MMC/SD card that contains a software update file; the unit will recognize it, will tell you what software version your control head is currently running, and will ask you if you want to update the software in the unit to match that on the MMC/SD card. You can obtain software updates from the www.humminbird.com website. Use the illustration to locate the position of the MMC and SD slot cover, remove the cover, and then insert an MMC and/or an SD card into one or both slots - either slot can accept either an MMC or an SD card. The label on both types of cards should face down and away from you so that you're looking at the back of the card. Press down on the card until it clicks into place, then replace the slot cover and tighten the screw snugly - do NOT overtighten, as this will not improve water resistance, and may damage the cover.

93x Man _531370-1 A - vs4.qxd 2/18/2005 11:11 AM Page 9 À Inside the boat there is often a channel or conduit used for other wiring, this can be used to route cables. Be sure to route the cable as far as practical from the antenna cable of VHF radios or tachometer cables to reduce the possibility of interference. The transducer and GPS receiver cables should not be cut, and care should be used not to damage the cable insulation. Basic installation tasks that you must perform include: +_Installing the control head (choosing either gimbal or in-dash mounting) Installing the transducer (choosing either the transom mount, inside the hull mount, or trolling motor mounting method) Installing the GPS Receiver (if included) Installing the Speed accessory (if included) Testing the complete installation and locking the transducer position. The supplied Humminbird® transducer uses a two piece kicdkup mounting bracket. In addition, if you purchased a 937c DF Combo or 937c Combo model, you will want to install the included GPS antenna. NOTE: Accessories may require a separate purchase. You can visit our website at www.humminbird.com to order these accessories online or contact our Customer Resource Center at 800-633-1468.

CONTROL HEAD INSTALLATION

You have two choices for mounting your 900 Series" control head: + Gimbal mounting, where you use a surface on the boat, such as the dash, to mount the control head so that it can be tilted up or down, or +_In-dash mounting, where you cut a hole in the dash in order to allow the control head to be recessed into the dash, and the control head cannot be moved after mounting.

GIMBAL MOUNTING THE CONTROL HEAD

If you are gimbal mounting the Humminbird® 900 Series", you can pre-assemble the unit in order to plan the best mounting location. © "oser © Gimbal knob © GimbolBracket © £pansion ports - use for future accessories Parts and tools specific to gimbal mounting are: + Gimbal mounting bracket and screws + Gimbal mounting knobs and washers + Phillips head screwdriver + 5/16" socket wrench or flat head screw driver + Hand drill with various dll bits + Marine-grade silicone sealant.

1. Place the control head into the gimbal bracket. Make sure that the straight side

ofthe gimbal arm is against the back side of the control head.

2. Place a 1" (25 mm) diameter black washer on the gimbal knob and then thread

the knob and washer into the housing. Tighten the gimbal knob to secure the . 900 Series” control head to the mount. Repeat step 2 for the other side. You can now place the control head in various locations to decide which is best for 7 —| mounting. Rotating the mounting bracket to the top of the control head will allow for SR AN D: 1271 overhead mounting. The chosen mounting area should allow for sufficient room so the control head can pivot through the full tilt range and allow for easy removal and installation. NOTE: You can drill the cable pass hole underneath the gimbal bracket, allowing you to threadthe cables through the knockout hole in the mount: however, you cannot dil he hole directy under the mounting bracket, then you wil need to dril the cable pass hole behind the bracket, and will need to mount the hole cover there instead NOTE: When dhiling holes in fiberglass hulls it s best to start with a smaller bit and use progressively larger dl its to reduce the chance of chipping or flaking the outer coating Fil al holes with marine grade silicone sealant. NOTE: You must have underside access to the mounting location to pass the cables through to the surface Also, make sure that the mounting surface is adequately supported to protect the control head from excessive wave shock and vibration and provide wsibity while in operation

3. Afterthe mounting location has been determined, loosen the gimbal knobs and

remove the control head from the gimbal bracket. NOTE: Afternate hole patterns are available underneath the gimbal mounting bracket, and may match existing holes on the boat. If you choose to use one of these alternate hole pates, simply rit ut and use it to mount the bracket instead.

4. Place the gimbal bracket in the chosen position on the mounting surface and

mark the four mounting screw locations using a pencil or center punch. NOTE: Go to the installation instructions applicable to your transducer, GPS Receiver © “ounting Screus and accessories. Make the required installations and then run the cables to your control @ er head mounting location. Do not cut any cabling (except the power cable). f your cables © cimbol ountng cet are too short, extensions are available from your local dealer or online from wwwhumminbird.com.

5. Set the gimbal bracket aside and drill the four mounting screw holes using a

5/32" (4.0 mm) dril bit.

the cables must pass through a hole directly beneath the mounting bracket, mark and drill an additional 1° (25 mm) hole centered between the four mounting holes. Route the cables through the grommet, then press the grom- met in place around the cables and into the 1" (25 mm) hole. Pass the cables out of the back of the mounting bracket. Using needle-nose pliers, break out the tabs on the rear ofthe mounting base. You will need to break out the cable tabs for the number of cables you want to run to your control head. 6b.

Ifthe cables cannot be routed directly beneath the mounting bracket, mark and drill a 1° (25 mm) hole that will allow you to run the cables close to the bracket. Pass the cables through the 1° (25 mm) hole, routing the cables through the grommet and pressing the grommet into place. Place the hole cover over the mounting surface hole, then use it to mark the position of the two mounting screws. Remove the hole cover, drill the two mounting holes using a 9/64" (35 mm) bit, fill them with marine-grade silicone, then replace the hole cover and insert the #8 Phillips countersink wood screws. Hand-tighten only.

7. Place the mounting bracket on the mounting surface aligned with the drilled

holes and fill the mounting holes with marine grade silicone. Insert the four #10 Slotted-Hex wood screws into the mounting holes. Hand-tighten only. NOTE: Be sure that the cables pass through the slots on the hole cover or gimbal bracket breakout tabs and there is enough cable slack to allow for the control head t pivot through it full tit range.

You may shorten or lengthen the cable using 18 gauge multi-stranded copper wire. There are three different installation methods for your transducer: + _Transom Transducer +_ Inside the Hull Transducer + Trolling Motor Transducer. CAUTION: Some boats have 24 or 36 Volt electric systems, but the control head MUST be connected to a 12 VDC power supply: The control head power cable can be connected totheelectricalsystemaoftheboatatone find the section that describes the method of installation you wil be using, of two places: a fuse panel usually located near the console, or directly to the battery. NOTE: the included transducer will not work for your application, you may exchange it, NEW and UNASSEMBLED, with mounting hardware inuded, for a transducer appropriate for your application - often at ver lite or no charge. depending on the transducer Call the Humminbird® Customer Resource Center (800-633-1468) for details and pricing, or visit wwwehumminbirdcom, Product Support/Transducer Exchange for more information. NOTE: Due to the wide variety of hulls, only general instructions are presented in this installation guide. Each boat hull represents a unique set of requirements that should be evaluated prior to installation. n addition to the parts supplied, you will need a hand drill with various bis, a socket wrench (7/16" or 5/16, depending on transducer pe), a Philips a head screwdrver, and marine-grade silicone sealant. NOTE: When driling holes in fiberglass hulls it is best to start with a smaller bit and use progressively larger dl bits to reduce the chance of chipping or flaking the outer coating, NOTE: Make sure that the power cable is disconnected from the control head at the beginning of this procedure. a. lf a fuse terminal is available, use crimp-on type electrical connectors (not included) that match the terminal on the fuse panel. Attach the black wire to ground (+, and the red wire to positive (+) 12 VDC power. 1b. If you need to wire the control head directly to a battery, obtain and install an inline fuse holder and a 2.5 to 3 Amp fuse (not included) forthe protection ofthe unit. Humminbird® is not responsible for over-voltage or over-current failures. NOTE: In order to minimize the potential for interference with other marine electronics, a separate power source (such as a second battery) may be necessary You are now ready to install the transducer. Find the section that refers to your specific transducer installation method. Fill all holes with marine grade silicone sealant.

WARNING: Do not touch an active transducer during operation, as this may cause physical

discomfort and may result in personal injury in the form of tissue damage. Handle the transducer only when the power to the control head off

To determine transducer mounting location: you will be installing a transom mounted transducer, use the procedures in this section. You will have one ofttwo different types of transducer, based on whether you have a Single {931c or 937c Combo) or a Dual (931c DF or 937c DF Combo) frequency 900 Series" control head. There are two pieces to the transducer mount assembly: the pivot, and the bracket. The Single frequency transducer comes with a two-piece plastic bracket assembly, while the Dual frequency transducer comes with a two-piece metal and plastic bracket assembly. Findthe correct procedures for your transducertype. There are several procedures you will have to perform in order to install a transom-mounted transducer. They are: Determine transducer mounting location Mount the bracket to the boat (find the procedure for your transducer, either Single frequency or Dual frequency) Attach the pivot to the transducer (find the procedure for your transducer, either Single frequency or Dual frequency) Mount the transducer pivot assembly to the bracket (find the procedure for your transducer, either Single frequency or Dual frequency) Adjust the running position of the transducer (find the procedure for your transducer, either Single frequency or Dual frequency) Route the transducer cable Perform a final test of the transom transducer installation.

1. First, determine the best location on the transom to install the transducer.

Consider the following to find the best location: Itis very important to locate the transducer in an area which is relatively free of turbulent water. As a boat moves through the water, turbulence is generated by the weight of the boat, and the thrust of the propeller(s) - either clockwise or counter-clockwise. This turbulent water is normally confined to areas immediately aft of ribs, strakes or rows of rivets on the bottom of the boat, and in the immediate area of the propeller(s). Clockwise propellers create more turbulence on the port side. On outboard or inboard /outboard boats it is best to locate the transducer at least 15" (380 mm) to the side of the propeller(s). The best way to locate turbulence free water is to view the transom while the boat is moving. This method is recommended if maximum high-speed operation is a high priority. Ifthis is not possible, select a location on the transom where the hull forward of this location is smooth, flat and free of protrusions or ribs. The hydrodynamic shape of your transducer allows it to point straight down without deadrise adjustment. On boats with stepped hulls, it may be possible to mount the transducer on the step. Do not mount the transducer on the transom behind a step to avoid popping the transducer out of the water at higher speeds; the transducer must remain in the water for the control head to maintain the sonar signal. If the transom is behind the propeller(s), it may be impossible to find an area clear from turbulence, and a different mounting technique or transducer type should be considered (see Inside the Hull Transducer Installation).

There are several ways to route the transducer cable to the area where the control head will be installed. The most common procedure routes the cable through the transom into the boat. NOTE: Your transducer may not look exacty lite the transducer show in the ilustrations but twill mount in exact} the same way NOTE: Your boat may have a pre-existing wiring channel or conduit that you can use for the transducer cable.

1. Unplug the other end ofthe transducer cable from the control head. Make sure

that the cable is long enough to accommodate the planned route by running the cable over the transom. CAUTION! Do not cut or shorten the transducer cable, and try not to damage the cable insulation. Route the cable as far as possible rom any VF radio antenna cable or tachomneter cables to reduce the possibiit of interference. the cable i too short, extension cable are available to extend the transducer cable up to a total of 50" (15 m).

5. Plug the other end of the transducer cable back into the

control head connection holder. To perform a final test of the transom transducer installation: After transom transducer installation, please perform the final testing and then finalize the installation (see Test and Finish the Transducer Installation).

Determine the transducer mounting location: If you choose to mount your transducer inside the hull of your boat, perform the procedures in this section. The inside the hull mounting procedure is identical regardless of what type of transducer you have (Single or Dual frequency). In-hull mounting generally produces good results in single thickness fiberglass-hulled boats. Humminbird® cannot guarantee depth performance when transmitting and receiving through the hull of the boat, since some signal loss occurs. The amount of loss depends on hull construction and thickness, as well as the installation position and process. This installation requires slow-cure two-part epoxy. Do not use silicone or any other soft adhesive to install the transducer, as this material reduces the sensitivity of the unit. Do not use five-minute epoxy, as it has a tendency to cure before all the air bubbles can be purged, thus reducing signal strength. NOTE: lr-hull mounting requires an installed and operational control head NOTE: Your transducer may not look exactiy like the transducer shown in the ilustrations but will mount in exact} the same way. Preferred Mounting Area On strates (2272 Decide where to install the transducer on the inside of the hull. Consider the following to find the best location: + Observe the outside of the boat hull to find the areas that are mostly free from turbulent water. Avoid ribs, strakes and other protrusions, as these create turbulence. + AS a general rule, the faster the boat can travel, the further aft and closer to the centerline of the hull the transducer has to be located in order to remain in contact with the water at high speeds. Trial installation: You will not be able to adjust the mounting after an inside the hull transducer is installed. t is best, therefore, to perform a trial installation first that includes running the boat at various speeds, in order to determine the best mounting area before permanently mounting the transducer.

1. Plug the transducer into the control head, then power up the control head.

When the control head detects a functioning transducer, it will automatically enter Normal operating mode.

2. View the sonar signal at its best by holding the transducer over the side,

immersed in the water, so that it is pointing Straight down over a known flat bottom. Use the display to benchmark against the sonar signal that will be detected once the transducer is placed in the hull.

3. Place the transducer body face down at the identified mounting location inside

the hull, with the end that has the mounting ears pointed towards the bow of the boat.

93x Man _531370-1 A - vs4.qxd 2/18/2005 ‘Transducer Mounted Inside the Hull

4. Fill the hull with enough water to submerge the

transducer body. Use a sand-filled bag or other heavy object to hold the transducer in position. The transducer cannot transmit through air, and the water purges any air from between the transducer and the hull, and fills any voids in the coarse fiberglass surface.

5. View the sonar signal on the display and compare

against what you observed in Step 2, making sure that the boat is in the same location as it was during your observations in Step 2. If the results are comparable, move on to Step 6. Otherwise, locate a new position in the hull and repeat Steps 3 through 5.

6. Run the boat at various speeds and water depths while observing the screen on

the control head. If depth performance is required, test the transducer in water À at the desired depth. Ifthe performance is acceptable, move on to Step 7. fthe performance is not acceptable, repeat Steps 3 through 6.

7. Once you have determined the best mounting location using the above steps,

mark the position of the transducer. Route the cable:

1. Oncethe mounting location is determined and you have marked the position of

the transducer, route the cable from the transducer to the control head. 11:11 AM Page 23 + Permanently mount the transducer:

1. Make sure the position of the transducer is marked.

2. Remove the water from inside the hull and thoroughly dry the mounting

surface. If the surface is excessivelÿ rough, it may be necessary to sand the area ‘to create a smooth mounting surface.

3. Slowly and thoroughly mix an ample quantity of two-part slow cure epoxy.

Avoid trapping air bubbles.

4. Coat the face of the transducer and the inside of the hull with epoxy.

5. Press the transducer into place with a slight twisting motion to purge any

trapped air from undemeath, keeping the end of the transducer that has the mounting ears pointed forward, towards the bow oftthe boat. NOTE: Proper operation requires the end of the transducer that has the mounting ears to face towards the bow of'the boat.

6. Weight the transducer so that it will not move while the epoxy is curing.

NOTE: When the epoxy cures, no water is necessary inside the hui.

7. you unplugged the transducer cable at the beginning oftthis procedure, plug

it back into the control head. NOTE: Neither water spilled gasoline, nor oi will affect the performance of the transducer.

If you want to install the transducer on a trolling motor, use this procedure. Several styles of the transducer are compatible with trolling motor mounting. If you have a trolling motor bracket, refer to the separate installation instructions that are included with the bracket. NOTE: After trolling motor transducer instalation, please perform the final testing and then finalize the installation (see Test and Finish the Transducer Installation). If you don't have a trolling motor transducer, there are several options: + You may purchase a rolling Motor Adapter kit that will allow you to mount the transducer on the trolling motor. + You may also exchange your NEW and UNASSEMBLED transducer (with mounting hardware included) for a trolling motor transducer. There are also several transducer switches available that support the following configurations: +_ Two control heads with one transducer +_ Two transducers with one control head. NOTE: Cal! the Humminbird® Customer Resource Center (800-633-1468) for details and pricing, or visit wehumminbird.com for more information. When you have installed both the control head, the transducer, and accessories and have routed all the cables, you must perform a final test before locking the transducer in place. Testing should be performed with the boat in the water, although you can initially confirm basic operation with the boat out of the water. NOTE: f you have installed an in-hull mount transduce, this procedure does not apphyasthe transducer already locked in place.

1. Press POWER once to turn the control head on. There will be an audible chirp

when the button is pressed correctiy. If the unit does not powerup, make sure that the connector holder is fully seated and that power is available.

2. fall connections are correct and power is available, the control head will enter

Normal operation. If no transducer is detected (or one is not connected), the unit will go into Simulator mode and will indicate this by displaying the word Simulator on the control head display. NOTE: The transducer must be submerged in water for relable transducer detection 3._ If the bottom is visible on-screen with a digital depth readout, the unit is working properly. Make sure that the boat is in water greater than 2ft (6 m) but less than the depth capability of the unit, and that the transducer is fully submerged, since the sonar signal cannot pass through air.

4. If the unit is working properly, gradually increase the boat speed to test

high-speed performance. Ifthe unit functions well at low speeds but begins to skip or miss the bottom at higher speeds, the transducer requires adjustment. Angling the rear of the transducer downward and/or lowering the transducer farther into the water will help achieve depth readings at high speeds. the left side ofthe fish arch is longer than the right side, then the back ofthe transducer is angled too far downward. If the right side of the fish arch is longer than the left side, then the back of the transducer is angled too far upwards.

93x Man _531370-1 A - vs4.qxd 2/18/2005 NOTE: may not always be possible to get symmetrcal fish arches and high speed depth readings at the same time. Due to the wide variety of boat hulls however its not always possible to obtain high speed depth readings NOTE: it is ofien necessary to make several incremental transducer adjustments before optimum high speed performance is achieved. Once you have reached a consistently good sonar signal at the desired speeds, you are ready to lock down the transducer settings. 5a. 1f you have a Single frequency transducer, mark the transducer bracket location on the transom with a pencil, then pop up the bracket to reveal the mounting screws.

The Speed accessory incorporates a paddlewheel-type speed sensor in a highimpact plastic housing. The module is intended for installation on the transom, and will work well on almost any boat. In addition to the parts supplied, you will need a hand drill with various bits, marine- grade silicone sealant, and a Phillips head screwdriver. Install the Speed accessory:

Locate an area on the transom of your boat that will be 6” to 8” or farther from the transducer(s). This area must also maintain contact with the water, even at high speeds. Do not mount the accessory directly in front of the propeller or outdrive, and make sure that there are no protrusions such as ribs, rows of rivets, or transducers directly forward of the mounting location, as these may affect the flow of water over the paddlewheel. Align the accessory on the transom so that the lower edge is flush with the hull ofthe boat and the tab on the bottom of the housing aligns with the bottom of the hull, and mark the hole locations. fthe transom angle is excessive, a fairing block may be needed to level the paddlewheel for proper operation. On fiberglass hulls, it is best to start with a smaller drill bit and use progressively larger bits to reduce the chance of chipping or flaking the outer coating. Drill two 9/64” (3.5 mm) mounting holes approximately 3/4” (19 mm) deep. Seal the mounting holes with marine-grade silicone sealant, and attach the module to the transom using the two washers and two screws provided. Hand tighten only!

93x Man _531370-1 A - vs4.qxd 2/18/2005 11:12 AM Page 33 P is important to understand the significance of the 900 Series“ display. The display does NOT show a literal 3-dimensional representation of what is under the water. Each vertical band of data received by the control head and plotted on the display represents something that was detected by a sonar return at a particular time. As both the boat and the targets (fish) may be moving, the returns are only showing a particular segment of time when objects were detected, not exactly where those objects are in relation to other objects shown on the display.

REAL TIME SONAR (RTS) WINDOW

A Real Time Sonar (RTS®) Window appears on the right side of the display in the Sonar View only. The RTS® Window always updates at the fastest rate possible for depth conditions and shows only the returns from the bottom, structure and fish that are within the transducer beam. The RTS® Window plots the depth and intensity of a sonar return. (See Sonar Menu: RTS® Window). The Narrow RTS® Window indicates the sonar intensity through the use of colors. Red indicates a strong return and blue indicates à weak return. The depth of the sonar return is indicated by the vertical ion placement of the rétum on the display depth scale. The Wide RTS® Window indicates the sonar intensity through the use of à bar graph. The length of the plotted return provides an indication of whether the return is weak or strong. The depth of the sonar retum is indicated by the vertical placement of the return on the display depth scale. As the boat moves, the unit charts the changes in depth on the display to create a profile of the Bottom Contour. The type of bottom can be determined from the return charted on the display. A Hard Bottom such as compacted sediment or flat rock appears as a thinner line across the display. À Soft Bottom such as mud or sand appears as a thicker line across the display. Rocky Bottoms have a broken, random appearance. NOTE: À sloping bottom will be represented as a thicker line across the display. Harder bottoms ÿpicaly wil be displayed with red and softr bottoms typical}y will be displayed with blue The sonar returns from the bottom, structure and fish can be represented as either Structure ID® or WhiteLine®. See Sonar Menu: Bottom View for details on how to set the bottom view. Structure ID® represents weak returns in blue and strong returns in red.

93x Man _531370-1 A - vs4.qxd 2/18/2005 11:12 AM Page 34 WhiteLine® highlights the strongest sonar returns in white, resulting in a distinctive outline. This has the benefit of clearly defining the bottom on the display. KEY FUNCTIONS Your 900 Series" user interface consists of a set of easy-to-use keys that work with various on-screen views and menus to give you flexibility and control over your fishing experience.

Ifthe power output of your boat's engine is unregulated, the control head may be protecting itself using its overvoltage protection feature. Make sure the input voltage does not exceed 20 Volts. The transducer position may need to be adjusted. À mix of air and water flowing around the transducer (cavitation) may be interfering with the interpretation of sonar data. See your Installation Guide for suggestions on adjusting the transducer position. Electrical noise from the boat's engine may be interfering with sonar reception. See Finding the Cause of Noise for more information. Sonar readings may be affected ifthe transducer is not positioned correctly (i.e.mounted at an angle, not straight down), or there is some kind of mechanical interference, either because it is mounted inside a hull that is too thick for proper sonar transmission, the bond between the transducer and the hull is not airtight, or because the transducer is dirty. Check with your Installation Guide for guidance on re-positioning the transducer, and make sure the transducer is clean. Low battery voltage may be affecting the power of signal transmission. Electrical noise from the boats engine may be interfering with sonar reception. See Finding the Cause of Noise for more information.

Electrical noise usually affects the display with many black dots at high speeds, and high sensitivity readings. One or more of the following sources can cause noise or interference: Possible Source of Noise Isolation Other electronic devices Turn off any nearby electronic devices to see if the problem goes away, then turn them on one at a time to see if the noise re-appears. The boat engine To determine whether the boat's engine is the source of the noise, increase the RPMs while the boat is in neutral and stationary to see if the noise increases proportionately; if noise appears when you rev the engine, the problem could be the spark plugs, alternator, or tachometer wiring. Replace the spark plugs with resistor plugs, install an alternator filter, or route the control head power and transducer cables away from the engine wiring. Cavitation from the boat's propeller Turbulence created by the propeller can cause noise; make sure the transducer is mounted at least 15” (38 cm) from the propeller, and that the water flows smoothly over the face of the transducer at all times.
