Introduction Thank you for your purchase of the Citizen CYBER AQUALAND. Please read this manual carefully before using your watch to ensure that it is used properly. Furthermore, make sure to store this manual in a safe place for future reference as necessary. CYBER AQUALAND is a divers watch containing a built-in dive computer and provided with its own depth gauge. The watch is able to automatically store various data (maximum depth, dive time, etc.) generated during diving as well as diving profile data, and display that data in the form of log data. By installing AQUALAND GRAPH 2001 in your personal computer from the CD-ROM provided with the watch, you can incorporate data stored in the watch in your PC using the communication unit and infrared communication interface provided. You can enter text into diving data that has been incorporated into your PC, generate graphs of diving data or attach still pictures or animated image data all with a simple procedure, and then manage this data collectively in the form of diving logs. Since these logs can be printed out or converted into HTML documents, storage of diving records is both simple and convenient. In addition, the use of CAPgm, which is installed simultaneous to installation of AQUALAND GRAPH 2001, makes it possible to make various watch settings (including travel time, alarm and timer settings) while also allowing different graphics to be displayed on the watch for different days. We hope that the use of CYBER AQUALAND will allow you to get even more enjoyment out of your recreational diving activities.

• To users using a previous HYPER AQUALAND product (Model No. D20*): +1f you are using the DOS version or Windows Ver. 1/Ver. 2 of AQUALAND GRAPH (HYPER AQUALAND dedicated software), you can use existing diving data managed with each version of AQUALAND GRAPH by importing that data to AQUALAND GRAPH

+ HYPER AQUALAND data can also be received using AQUALAND GRAPH 2001 software. Please note, however, that the type of communication unit and connection cable differ between CYBER AQUALAND and HYPER AQUALAND. (Please refer to the AQUALAND GRAPH 2001 instruction manual contained on the CD- ROM provided for further information regarding the procedures for importing and receiving data.) Safety Precautions: Observe at AII Times The following provides an explanation of those matters that should be observed at all times to prevent injury to the wearer or other persons as well as damage to property before they occur. AThe degree of injury or damage resulting from incorrect use while ignoring the indicated matters is classified and explained using the following markings. Î WARNING This marking indicates matters for which there is the risk of death or serious injury. Î CAUTION This marking indicates matters for which there is the risk of injury or property damage only. The types of matters to be observed are classified and explained using the following mark (the following indicates two examples of icons). Â\ This mark indicates that caution or attention is required. O This mark indicates prohibited matters. Z\ WARNING Read this manual carefully and pay attention to all warnings. Make sure you fully understand the use, displays and limitations of the watch. Neglecting to understand and follow the instruction manual may cause errors to be made during diving that may lead to serious injury or death.

/\ WARNING + Diving is a potentially dangerous sport. When using this watch for diving, make sure to have a correct understanding of this watch as described in this manual and strictly adhere to the procedures for its operation. The watch may not function properly if handled in a manner not described in this manual. + This watch should not be used as a primary instrument for diving. -Diving while using this watch is limited to recreational diving (no decompression diving) in salt water at a water temperature of +10°C to +40°C (50°F to 104°F). This watch cannot be used for decompression diving, saturation diving using helium gas, diving at high altitudes (300 m (1000 ft) or more above sea level) or diving outside the above temperature range. In addition, this watch can not be used for nitrox diving (diving using a mixed gas of oxygen and nitrogen in which the oxygen concentration is richer than air tanks used for ordinary diving). - Although this watch provides data for decompression diving in cases of emergency, never attempt to use this watch for decompression diving since this is potentially dangerous. In addition, the watch does not display depth correctly when used in water other than salt water (specific gravity: 1.025). + Even recreational diving can be dangerous. Users are requested to obtain the proper scuba diving training from a qualified instructor, acquire the necessary experience and skills for safe diving and completely master the handling and operation of this watch before using this watch as an auxiliary instrument for diving. Insufficient or improper training may cause errors to be made during diving that may lead to serious injury or death. + Sudden atmospheric fluctuations and changes in water temperature may have an effect on the display and performance of the watch. Since this watch is not intended to be used as a specialized instrument, and is only intended to display information to serve as a reference for minimizing decompression sickness and other dangers, it is not designed to guarantee the safety of the user. Always make sure to use this watch in combination with other instruments (such as a diving table, residual pressure gauge and water depth gauge). Never use it as a primary instrument for diving. + This watch is designed on the premise of being used only by one person. Never lend to or share this watch with another person while resting on the surface (while the surface mode is activated). In addition, do not use the data displayed by the watch as diver data for persons other than the user. Z\ WARNING In order to ensure safe diving, dive while allowing an adequate margin of safety relative to the displayed no-decompression limit time. /\ WARNING Never dive in a manner that requires a decompression stop (decompression diving). If decompression diving should happen to occur, immediately start to ascend while observing an ascent rate of no more than 18 m (60 ft)/min. Make a decompression stop while ascending in accordance with decompression stop instructions. When making a decompression stop, never ascend to a depth less than the instructed depth. In addition, since it is difficult to maintain a constant depth when there are high waves and so forth, make decompression stops at depths a little deeper than the instructed depth to prevent decompression sickness.

• A permanent error (ERROR) occurs when continuing to dive while ignoring decompression Stop instructions during the course of decompression diving, and the watch will not switch to the dive mode for 24 hours after that time /\ WARNING Avoid traveling in an aircraft while the surface mode is activated. Traveling in an aircraft without allowing sufficient time to rest after diving results in the risk of decompression sickness. It is recommended to avoid traveling in an aircraft for at least 24 hours after diving whenever possible even if the surface mode is no longer displayed. There are no rules for completely preventing decompression sickness caused by flying in an aircraft after diving. /\ CAUTION Skin diving after scuba diving is not recommended. It is recommended to avoid skin diving for at least two hours after scuba diving and not to exceed a depth of 5 m (15 ft). /À Data Storage - The various data recorded in the watch may be lost when subjected to incorrect use or the effects of strong electricity and electrical noise as well as during a malfunction and repair. Always make sure to keep a separate record of important data recorded in the watch. Diving data in particular should be transferred to your PC or recorded in a log book as quickly as possible.

In addition, try to start a dive after first sufficiently charging the watch before diving to avoid having the watch become insufficiently charged while diving.

ary instrument for diving. + Confirm that "ERR" (error) or "CHK" (check) is not displayed on the display. + Confirm that the band is securely attached to the watch body. + Confirm that the band and glass are free of cracks, scratches, chips and other abnormalities. + Confirm that the time and date are set correctly. + Confirm that the depth alarm and dive time alarm are set correctly. + If there is a considerable difference between the watch temperature and the water temperature (such as in cases of entering water after having the left the watch in bright sunlight), water depth cannot be measured accurately. In such cases, immerse the watch in the water for at least 5 minutes and then dive after the watch temperature has become acclimated to the water temperature. <Cautions During Diving> + Avoid ascending too rapidly. Rapid ascending can cause decompression sickness and have other detrimental effects on the body. Observe the safe ascent rate at all times. + Please note that when underwater, it may be difficult to hear the sound of the dive alarm or other alarms depending on surrounding conditions (such as breathing noise and air bubble noise) and the manner in which the watch is worn. - Be careful not to run out of air. This watch does not manage the amount of air remaining in the air tank. The diver is responsible for managing the amount of air remaining. In the event the watch should happen not to operate properly while underwater, either ascend immediately while following the instructions of the instructor or begin ascending immediately at an ascent rate of no more than 18 m (60 ft) per minute and make a safety stop at 5 m (15 ft) as long as your air lasts. <Cautions After Diving> + Make sure to rest sufficiently after diving by checking the surface mode (which measures the amount of time elapsed after diving and no fly time). + After removing any moisture, mud, sand or other foreign matter adhered to the watch by thoroughly rinsing with fresh water, completely wipe off the watch with a dry cloth. + Do not attempt to remove the sensor cover or poke at it with a sharp object to attempt to remove any dirt or debris trapped in the pressure sensor. In addition, do not spray the pressure sensor with air under high pressure such as that from an air gun. In the case that debris has become trapped in the pressure sensor, rinse it out with fresh water. If it is still unable to be removed, consult your nearest Citizen Service Center. ÂÀ CAUTION Fresh Water Diving + This watch is designed on the premise of diving in salt water. It will not display water depth accurately in water other than salt water. + Only use the watch after receiving special safety training when using the watch for diving in fresh water. + Since this watch displays water depth as converted based on salt water (specific gravity: 1.025), the true water depth in fresh water is actually 2.5% deeper than the displayed water depth. + Example: Water depth displayed as 20 m x 1.025 = 20.5 m (actual water depth) (40 ft x 1.025 =41 ft)

EWarning Functions This watch is equipped with various warning functions for the purpose of avoiding risks and problems when diving as much as possible.

• Do not dive in a manner that activates any of the warning functions. Since the degree of risk varies according to experience, physical condition and diving conditions, do not assume that diving is completely safe just because none of the warning functions are activated. Please use the warning functions as a general indicator of diving safety. Insufficient Charge Warning When the watch becomes insuficientiy charged, "BATT" flashes in the lower left comer of the display in all of the sub-modes of the standard mode. Operation of the following functions is limited while this warning function is activated. + The watch does not switch to the dive mode even if the water sensor À gets wet._ (The watch automatically switches to the battery charge ù indicator display of the system monitor mode when the water sensor Flàshing gets wet.) + None of the alarms sound. + Data cannot be transferred by infrared communication. (However, data can be transmitted to a personal computer by USB communication.) + The EL light is not illuminated. When this warning function is activated, charge the watch by attaching to the communication unit as soon as possible. The display will return to normal once the watch is sufficiently charged.

• None of the dive alarms sound when the insufficient charge warning function is activated during diving. Although the dive computer will function normally for about 30 minutes after "BATT' starts to flash, the log data for that dive is not recorded. Promptiy begin to ascend it this warning function is activated during diving

• IFthe watch remains insufficientiy charged after the insufficient charge warning function has been activated, it switches to the low power mode after about 2 days. Please note that if the watch continues to be left uncharged in the low power mode, all functions stop and all watch settings return to the initial (default) settings File Error Warning When the amount of available memory in flash memory becomes low, "FILE" flashes in the lower left corner of the display in all of the sub- modes of the standard mode as well as in the dive mode. The watch automatically switches to the flash memory status display of the system monitor mode when the water sensor gets wet while this warning function = is activated. Please note that although it is possible to use the watch for diving in this state, log data may not be recorded in flash memory during Flashing diving. The file error waming function is also activated and additional log data is not recorded if the duration of a single dive exceeds 2 hours or if more than 15 dives are made in a single day. The file error warning function may also be activated when the water temperature during diving is low. It may not be possible to receive watch settings by data communication while the file error warning function is activated.

When the watch has switched to the file error warning display, perform the garbage collection procedure in the system monitor mode of the standard mode. The display returns to normal following completion of garbage collection. Abnormal Pressure Detection Error Warning When abnormal atmosphere pressure is detected during use on land, or when ascending to high locations more than 4000 m (13000 ft) above sea level, "ERR" (Error) flashes in the lower left comer of the display. — The watch does not switch to the dive mode even if the water sensor Flashing gets wet while this warning function is activated. If "ERR" does not disappear from the display even after a long period of time, there may be a problem with the pressure sensor. When this happens, discontinue using the watch and consult a Citizen Service Center. Water Sensor Check Warning If the preliminary dive display continues to be displayed for more than 1 hour after the water sensor has gotten wet and the watch has switched to the preliminary dive display in the dive mode, "CHK" (Check) flashes in the lower left corner of the display to inform the wearer that the water sensor should be checked. **CHK" also flashes when the watch returns to the normal display from any of the correction states, when the watch is returned to the time mode of the Flashing standard mode from the infrared communication mode, and when the water Sensor is operating during the all reset procedure. The watch does not switch to the dive mode (water depth measurement display) when "CHK" is flashing. To check the sensor, remove any debris or moisture from the water sensor with a dry cloth. The display returns to normal when the water sensor is canceled. Ascent Rate Warning When the ascent rate during scuba diving exceeds 18 m (60 ft)/min, the ascent rate warning alarm sounds for 5 seconds and "SLOW" and an ilustration of a turtle are displayed at the bottom of the display. The ascent rate warning alarm stops sounding when a proper ascent |S[_(}} lie rate is resumed.

• The ascent rate warning alarm does not sound during skin diving (continuous diving for less than 3 minutes at a depth of 1 m or more) Abnormal Depth Warning When a sudden change in depth of more than 4 m (13 ft)/sec is detected during diving, the watch assumes that the watch has reached an abnormal depth. At this time, "ERR" and the diver mark are alternately displayed in the lower left comer of the display. Once "ERR" has been displayed during diving, it continues to be displayed until the dive mode is terminated. /\ CAUTION Avoid using the watch in environments where sea bottom drilling equipment or similar machinery is in use. The vibrations from such equipment may cause a change in water pressure of "4 m (13 ft) or more per second" to be locally and momentarily applied to the pressure sensor of the watch, causing "ERR" to be displayed and preventing water depth from being displayed correctiy.

In addition, "ERROR" is displayed when Flashing the watch is switched to the dive plan mode, and the no- decompression limit time is not displayed.) Ait

BDiving Terms Used by this Watch The following provides an explanation of the diving terms displayed by this watch along with their basic meanings. <Algorithm> This watch employs the calculation formula of the Canadian Defense and Civil Institute of Environmental Medicine (DCIEM). <Scuba Diving and Skin Diving> This watch automatically distinguishes between skin diving and scuba diving according to the following conditions, and records log data separately for each type of diving. + Scuba diving: Continuously diving for 3 minutes or more to a depth of 1 m (4 ft) or more + Skin diving: Continuously diving for less than 3 minutes to a depth of 1 m (4 ft) or more <One Dive> In this watch, one dive constitutes the time from initially diving to a depth of 1 m (4 ft) (start of dive) from the preliminary dive mode state to the time the dive mode is terminated (end of dive). <No-Decompression g and No-Decompression Limit (NDL) Time> No-decompression diving refers to diving that allows the diver to ascend to the surface without stopping for decompression during the course of ascending following completion of a dive. The limit time during which this no-decompression diving is allowed is referred to as the no-decompression limit time. No-decompression limit time varies according to the diving depth and diving time of the previous dives. <Satety Stop> Safety stop refers to a temporary stop made during ascending for safety reasons in order to promote expulsion of nitrogen in the body, and is performed even if the no- decompression limit time has not been exceeded. In the case of having dove to a depth of 18 m (60 ft) or more, a safety stop should always be made at 5 m (15 ft) of depth to ensure safety. <Decompression Diving> This refers to diving beyond the no-decompression limit time. Decompression diving is extremely dangerous since nitrogen accumulates in the body beyond allowable levels. Never dive in this manner. <Decompression Stop> This refers to a stop that must be made to ensure the necessary decompression in the case of having performed decompression diving. It is necessary to make a decompression stop at a predetermined depth (decompression stop instructed depth) and predetermined time (decompression stop instructed time) when ascending. <Total Ascending Time> This refers to the minimum time required to ascend to the surface from the current depth in the case of ascending at the rate of 18 m (60 ft}/min or less while making a decompression stop in accordance with the decompression stop instructions during decompression diving.

<Body Nitrogen Level> This refers to the amount of nitrogen dissolved in the body as a result of diving. This watch displays a general indicator of the amount of nitrogen dissolved in the body in the form of a bar graph. The higher the level of the black portion of the graph, the greater the body nitrogen level. <Total number of Dives (Log Count)> This indicates the total number of dives for scuba diving.

• Arbitrarily resetting the number of past dives with the “CAPgm" software provided before using the watch for diving enables this to display the total number of scuba dives made throughout your life <Dive Date> This is the date (year, month and date) on which a dive was made. <Dive Number> This is the number of dives made in one day. A maximum of 15 dives are counted per day for skin diving and scuba diving, respectively.
• This indicates the number of a dive for a particular dive date. The counter is reset to 1 when the day changes. <Surface Interval Time (S.I. Time)> This refers to the elapsed time following completion of scuba diving (surface interval time (S.I. Time)). This watch measures surface interval time up to a maximum of 24 hours.

• S.1. Time as referred to in the scuba log mode represents the elapsed time from completion of the dive of the previous log until the start of the dive of the current log. <Dive Time> This is the total time at a depth of 1 m (4 ft) or more during a single dive.

• Measurement of dive time starts when first going below a depth of 1 m (4 ft}, and stops when depth reaches less than 1 m (4 fd. However, if a dive is resumed to a depth of more than 1 m (4 ft} within 10 minutes from the time measurement of dive time stopped, dive time is continued to be measured from the time measurement stopped <Time In> This is the time when the depth exceeds 1 m (4 ft) for the first time during the dive. <Minimum Water Temperature (Min.w.temp)> This is the minimum water temperature encountered during the course of a single dive. <Maximum Depth (Max. Depth)> This is the depth when having dove the deepest during the course of a single dive. <Average Depth (Ave. Depth)> This is the average depth during the course of a single dive.
• This refers to the average value of depth measured for every 5 seconds of dive time <Profile Log> The watch displays a simple graph of the changes in depth during a dive.

• Data relating to depths measured every 5 seconds and water temperature measured every 5 minutes can be confirmed on a personal computer.

Using the Dive Plan Mode This mode is used to plan the next dive. In this mode, the no-decompression limit time according to the first dive and repetitive dives can be displayed, and dive alarms can be set.

3. Deleting Log Data

Individual sets of log data cannot be deleted. When a new dive is made when there are already 100 sets of dive data recorded for the total dive data of scuba diving log data and skin diving log data, the oldest log data is automatically deleted. /\ CAUTION It is strongly recommended to promptly record important log data in another storage medium. When a new dive is made and there are already 100 sets of dive data recorded for the total dive data of scuba diving log data and skin diving log data, the oldest log data is automatically deleted. In addition, since there is also the possibility of data being lost due to a malfunction in the watch or during repairs or inspections, it is recommended to promptly transfer data to a personal computer following completion of diving. Please note that the manufacturer cannot be responsible for data that is lost due to a malfunction.

Using the Dive Mode This mode is used to measure depth underwater. When the water sensor detects water in any mode other than the transfer mode and low power mode, the watch automatically switches to the dive mode. When the depth exceeds 1 m (4 ft) during the preliminary dive display, measurement of depth begins enabling the watch to display necessary information including current depth, dive time and max. depth for the diver.

The horizontal axis of the graph represents elapsed time, while the vertical axis represents changes in depth over a range of #1 m (4 ft} from the decompression stop instructed depth

Instructed Instructed depth time /\ WARNING Never dive in a manner that requires a decompression stop (decompression diving). If decompression diving should happen to occur, immediately start to ascend while observing an ascent rate of no more than 18 m (60 ft)/min. Make a decompression stop while ascending in accordance with decompression stop instructions. When making a decompression stop, never ascend to a depth less than the instructed depth. In addition, since it is difficult to maintain a constant depth when there are high waves and so forth, make decompression stops at depths a little deeper than the instructed depth to prevent decompression sickness.

• À permanent error (ERROR] occurs when continuing to dive while ignoring decompression stop instructions during the course of decompression diving, and the watch will not switch to the dive mode for 24 hours after that time.

2. Depth Measurement

This watch measures depth every second, and continuously displays the current depth in 0.1 m (1 ft) units during the course of diving. + Measuring range: 1 m to 80 m (4 ft to 266 ft)

• O m (0 ft is displayed at depths of less than 1 m (4 ft}, while -- mis displayed at depths greater than 80 m (266 ft).

• When an error has occurred in depth measurement during the course of diving, "ERR' and the diver mark are alteately displayed until that dive is completed.

3. Dive Time Measurement

The elapsed time of dives made to a depth of more than 1 m (4 ft) is displayed. Measurement of dive time starts automatically when the depth exceeds 1 m (4 ft) for the first time, and stops when the depth again is less than 1 m (4 f). However, if a dive is resumed to a depth of more than 1 m (4 ft) within 10 minutes from the time measurement of dive time stopped, dive time is continued to be measured from the time measurement stopped. Dive time is displayed for up to 9 minutes 59 seconds from the start of measurement in 1 second units. Beyond that time, dive time is displayed in 1 minute units. + Measuring range: 0 minutes 00 seconds to 999 minutes 59 seconds

4. Water Temperature Measurement

The watch starts to measure water temperature beginning 1 minute after the depth exceeds 1.0 m, and measures at 1 minute intervals during the course of diving. The most recently measured water temperature is displayed in 1°C (1°F) units during the time button (A) is pressed during the scuba diving display. (The water temperature measured in 0.1°C (0.18°F) units is displayed after rounding to the nearest 1°C (1°F) unit.) + Measuring range: -9.4°C to +40.0°C (15°F to 104°F)

5. No. of Dives Per Day and Recording Log Data

A maximum of 15 sets of log data can be recorded in a single day for both skin diving and scuba diving. When the number of sets of log data exceeds 15, log data is no longer recorded during diving. Even though log data is not recorded, the watch will continue to measure depth and perform its various other functions during diving. When the number of dives in one day is such that the number of skin dives is 15 or more and the number of scuba dives is 14 or less, although the watch displays "FILE" when the dive is started based on the judgment of the watch being used for skin diving, it judges that the watch is being used for scuba diving 3 minutes later at which time "FILE" disappears from the display and the dive is recorded as log data.

Problem Low display contrast Possible Cause The ambient temperature may be too low. The display contrast may decrease in low- temperature environments. Solution The display retumns to normal when the watch is retumed to a normal temperature. When desiring to temporarily increase the contrast in low-temperature environments, you can correct the contrast in the correction state of the time mode of the Standard mode. À permanent error occurred during the previous dive (decompression diving) If a permanent error occurs during diving, the watch cannot be switched to the dive mode for 24 hours after completion of that dive. The permanent error will be reset after 24 hours have elapsed. Excessive time required for switching modes the amount of flash memory being used becomes excessively large, the amount of time required to switch modes and call up log data may become slightly longer. Perform the garbage collection procedure in the system monitor mode of the standard mode. If a large amount of diving log data is recorded, however, slightiy more time may still be required to call up the display as compared with the initial state. This is not a malfunction. The water sensor check warning (°CHK* display) has been activated. After rinsing off any debris around the water sensor with water, completely wipe off the water with a dry cloth. Unable to end dive mode Hthe water sensor remains activated by perspiration or other moisture in a high altitude environment subject to rapid changes in air pressure in a short period of time (such as when traveling in an aircraft), when there is a change in air pressure of 1000 hpa or more, the depth display may not return to O m (0 f) preventing the dive mode from being canceled even after returning to a low altitude (on the ground). The watch returns to the time mode of the standard mode when button (D) is pressed for at least 10 seconds.

• However, the diving data for that dive is not recorded when the dive mode is ended with this procedure. The "CHK" (Check) display remains displayed for a long time. The water sensor continues to remain activated due to the presence of sand, debris or perspiration and so forth adhering to the water sensor. After rinsing off any debris around the water sensor with water, completely wipe off the water with à dry cloth. The "ERR" (Error) display remains displayed for a long time. +"ERR" is displayed during use on land (except for at high altitudes of 4000 m (13000 ft) or more above sea level) +"ERR" remains displayed for a long time after completion of diving This indicates a problem with the pressure sensor (‘ERR" may be displayed at high altitudes of 4000 m (13000 ft) or more above sea level). Discontinue using the watch and consult with a Citizen Service Center. (Refer to the section on "Warning Functions" for further details.) Alarm does not sound EL light is not illuminated The insufficient charge warning function (*BATT" display) has been activated as a result of the watch having become insufficiently charged (watch functions are limited when the watch has become insufficiently charged).
