1. Introduction

Congratulations on your choice of the TUSA IQ-700 Dive Computer. The IQ-700 is a compact and sophisticated dive instrument that will give you reliable, trouble free performance, dive after dive.

The information in this manual has been developed for your safety. Please read and understand this manual completely before using your new TUSA dive computer.

2. Key Features

• Display backlight
• User changeable battery

3. Common Sense Warnings

As is true of every piece of diving equipment, including all dive computers, the IQ-700's abilities are not limitless. There are certain limitations and restrictions of which you must be aware, and certain precautions you must take when using the IQ-700.

WARNINGS

Before using the IQ-700, it is extremely important you read the following points- as well as similar warning and caution notices that appear throughout this manual. Failure to do so could result in damage to or loss of equipment, serious personal injury, or death.

The IQ-700 is designed for use by certified, recreational divers who have maintained a sufficient level of knowledge and skill proficiency through a combination of formal training, ongoing study and experience. It is not intended for use by persons who lack the qualifications, and thus may not be able to identify, assess, and manage the risks scuba diving entails. Use of the IQ-700 in conjunction with Enriched Air Nitrox (EANx) further requires that the diver be trained and certified for Nitrox diving.

The IQ-700 is not intended for use by commercial, military or technical divers whose activities may take them beyond the commonly accepted depth limits for recreational diving.

The IQ-700 is designed for use by divers breathing either normal compressed air or Enriched Air Nitrox (EANx) mixtures whose fraction of Oxygen falls within a range of 22 to 50 percent for mix one, and 22-99% for mix two.

Although the IQ-700 is capable of calculating decompression stop requirements, this ability is provided as a safety feature only, should a diver accidentally exceed the No-Decompression Limits (NDLs). Dives requiring mandatory stage decompression carry substantially greater risk than dives made well within no-decompression limits.

Decompression diving is widely believed to entail substantially greater risk of decompression illness than dives made well within the No-Decompression Limits (NDL). The IQ-700 provides decompression stop information solely as a contingency in case divers accidentally exceed the No-Decompression Limits. It is not designed or intended for use as a tool to plan or execute dives that participants know will entail mandatory decompression.

WARNINGS

The IQ-700 is designed to be used by only one diver at a time. Divers should not share a single IQ-700, or any dive computer, on the same dive. Additionally, no diver should lend his or her IQ-700 to anyone else until it calculates that no measurable residual nitrogen remains after previous dives, and displays neither the “Desaturation Time” nor “No Fly” indicators while in Surface Mode. Further, no diver should use his or her IQ-700 for repetitive dives unless that same IQ-700 has accompanied him or her on all previous dives in the same repetitive dive series.

Neither the IQ-700, nor any other dive computer presently available, physically measures the amount of nitrogen present in body tissues, or the rate at which this nitrogen is being absorbed or released. Instead, the IQ-700 monitors depth and time, and uses this data to work a mathematical formula designed to emulate how individuals in good general health and whose physical characteristics do not place them among those at higher risk of decompression illness are assumed to absorb and release nitrogen from body tissues. Thus, the IQ-700 cannot compensate for factors such as age, obesity, dehydration, cold or exertion, which experts believe place divers at greater risk of DCI. If these, or similar factors apply to you, use the IQ-700, and any other dive computer or dive table, with even greater caution.

Experts still know surprisingly little regarding the exact nature and causes of decompression illness (also known as decompression sickness, DCI, or DCS). Susceptibility to DCI may vary substantially from person to person and from day to day. Neither the IQ-700, nor any dive computer or table, can guarantee that you will not suffer decompression illness. Even though you use these items correctly, you may still suffer DCI. Do not rely on the IQ-700 as your sole means of avoiding decompression sickness.

Experts recommend divers wait at least 24 hours following any dive before flying in an aircraft or driving to altitude. Failure to allow sufficient surface interval before doing so may substantially increase the risk of Decompression Illness (DCI).

Do not plan dives to depths deeper than those for which the IQ-700 is capable of displaying an available No-Decompression Limit. Doing so could cause you to exceed the No-Decompression Limits or limiting PO2 of 1.6 bar, which may in turn substantially increase your risk of decompression illness or CNS Oxygen Toxicity and can lead to serious personal injury or death.

4. Accessing Display Modes

There are some display modes that the IQ-700 enters and/or exits automatically. For example, by taking the IQ-700 underwater, you automatically activate its Dive Mode. Upon surfacing your IQ-700 will automatically enter Surface Mode.

To access other modes you may need to push one of the three large, grey buttons on the IQ-700's face. These are the A, B (mode), and C buttons. (Fig. 1)

You will find these buttons easy to use. In some instances you may need only press a button once and release it to achieve the desired result. In other instances, you may need to hold the button down until you get the result you wish. This manual will outline clearly which procedure to follow for each mode or task.

Throughout this manual display icons that blink are shown within a gray square.

5. Time Mode

Time mode is the IQ-700's default mode. In this mode the screen displays a minimum of the current date and time of day. Within 24 hours of surfacing from a dive, the IQ-700 will display additional information while in Time Mode. A description of the screens is shown below.

Normal Current time Nitrox PM 3:00|35 1:14 TIME Current date Mode Fig.2 Don't fly icon Desaturation time After Dive PGT graph NITROX icon Altitude rank Nitrox PM 3:00|35 13:18 7:26 O2 SURF.T N2 TIME OLI graph Surface time

Fig.3
Note: Blinking icons are shown in a square.

• Current time: This is the current time of day. (Fig. 2)
• Current date: This is the current date. (Fig. 2)
- Battery indicator Icon: This displays the current battery voltage shown)
- PGT (Pressure Gas in Tissue) graph: This indicates the level of Nitrogen with nine level indicators. (Fig. 3)
- OLI (Oxygen Limited Indicator) graph: This indicates the level of Oxygen limit with eight level indicators. (Fig. 3)
- Nitrox Icon: This Icon is ON when NITROX has been set MIX2. It blinks if the MIX1 and MIX2 setting is the default setting. (Fig. 3)
- Desaturation time (DESAT): This indicates the time remaining body's internal nitrogen is desaturated. (Fig. 3)

• Surface time (SURF.T): This is the surface interval time after a dive. The timer is started from when the depth shown in Dive mode reaches 5 feet (1.5m) or less. If the depth changes back to 5 feet (1.5m) or more in less than 10 minutes, the previous dive is continued. Surface time is continued for 48 hours. After that, surface time is turned off. (Fig. 3)
  • Mode: This display shows the computer in Time mode. (Fig. 2)
• Don't Fly Icon: While the computer calculates desaturation time this icon is displayed during Time Mode. When the computer has finished calculating desaturation time this Icon is turned off. (Fig. 3)
  • Gage mode Icon: If the computer is in Gage mode this icon will appear.

6. Battery Indicator

Battery Indicator Icon: This displays the current battery voltage, follows.

When battery voltage is 2.8V or above the battery Icon is OFF.

When battery voltage is 2.6 to 2.7 V the battery Icon blinks.

When battery voltage is less than 2.6 V the battery Icon is ON.

You cannot go into dive mode while the battery indicator Icon is blinking or ON. The Icon can be displayed during all other modes. Battery voltage is automatically measured during all modes except PC transfer and dive mode.

Important!

Once the battery indicator is blinking or ON you must return the IQ-700 to your local authorized TUSA dealer for battery replacement, or replace the battery yourself following the procedure outlined later in this manual. Before replacing your IQ-700's battery, be sure to upload or copy all dive log data to your log book, as the battery replacement process erases all such data from the IQ-700's memory.

7. Altitude Setting

Altitude setting: The IQ-700 automatically measures and calculates current location's altitude and displays the corresponding altitude rank. The relation between altitude rank levels and altitudes are shown below. A new altitude measurement and calculation is made once every ten minutes.

Altitude rank	Altitude range
0	0-900m(0-2952ft)
1	600-1800m(1968-5904ft)
2	1500-2600m(4920-8528ft)
3	2300-6000m(7544-19680ft)
Err	Over 6000m(over 19680ft)

Fig. 4

When the altitude is over 19680 feet (6000 meters), the display will blink while showing the altitude rank and ‘Err’ icons and the dive computer will not function until the altitude drops to a lower level (under 19680 feet (6000 meters)). The calculations of PGT, OLI and desaturation time are stopped when altitude is over 19680 feet (6000 meters), and ‘Err’ is displayed; however surface time continues to be counted. When the altitude is less than 19680 feet (6000 meters), the display shown before reaching that altitude is displayed again. The same displays and processing occur if the altitude cannot be measured for any reason.

Altitude measurements are made during all modes except Dive a transfer mode. The computer will display the current altitude setting in Time Mode and Plan Mode (In Dive Log mode the rank of the dive is displayed.)

Warning

The IQ-700 is not intended for use at altitudes above 19680 ft (6000 m). Diving at high altitudes carry an increased risk of decompressoin sickness.

Below are the Altitude Setting Icons for the rank of 0,1,2,3. If the altitude exceeds 19680 feet the icon will blink and the Err icon will be displayed. (Fig. 5)

Caution

• a change in the altitude rank will cause PGT graph to be displayed and desaturation time to be performed even if the PGT graph was not previously active.
• Never touch the water detection switch (D) or expose it to moisture when on an airplane or in any other environment where air pressure can change quickly.
• When the PGT graph is high (7 or 8 bars), a change in the altitude rank may cause the ninth level indicator to appear. To prevent this, never use the dive computer when going to high-altitude locations, since it will disable dive mode as a safety precaution. Normal function of the dive computer will be restored when PGT graph drops to 8 bars or less.
• A difference of one-minute may occur between when the PGT graph is turned off and when desaturation time is turned off.

Description of the Dive Log functions

The Dive log mode records various data during a dive when the dive depth is at least 5 feet (1.5m) and the dive time is at least 3 minutes. Data is recorded during each successive dive, and the log data storage capacity hours of dive time, or up to 60 log data entries. If the I exceeds 30 hours or the number of log data entries exceeds 60, the oldest data is automatically deleted. (See the section describing profile mode for further description of log data and profile data.) The logged data is described below.

• Log number: This indicates the number of the log entry being recorded among the recorded logs. (Fig. 13)
• Dive date/Dive start time/ Dive end time: This is diving information. Dive date is the date of the dive. Dive start time is the time at the start of the dive. Dive end time is the time at the end of the dive. Both Dive start time and Dive end time are displayed in 24 hour format. (Fig. 13)
• PGT (Pressure Gas in Tissue) graph: This represents the level of Nitrogen with nine level indicators at the end of the dive. (Fig. 14)

Description of Functions during dive mode

The are several different displays and functions available in DIVE mode including: non-decompression dive mode, decompression dive mode, safety stop condition, gage dive mode, and out of measuremer condition. The functions of each mode are described below.

Non-decompression mode (Fig. 27)

This is for a non decompression (NDL) dive.

Gage mode (Fig. 29)

The only functions that can be performed in this mode are the calculation, water temperature measurement, and dive time measurement. If you use this mode when diving, the IQ-700 remains in GAGE mode until 48 hours have elapsed. When using gage mode the safety stop function is not available.

Decompression Mode (Fig. 30)

This is used for dives that last longer than the NDL's. The DECO icon warning will continue until the advised depths are reached. If you ignore the DECO warning and go straight to the surface for longer than 10 minutes the display will freeze and all calculations will stop. The IQ-700 will switch automatically to TIME mode after 48 hours have elapsed. This information is recorded in the dive log. The IQ-700 can only switch to log, profile, or PC transfer mode while the calculations have stopped.

Safety Stop Timer (Fig. 28)

This timer shows the recommended safety stop while in dive mode. If the diver descends over 32 feet (9.9m), then comes up to a depth of 20 feet (6m), this value appears instead of NDL. Safety stop time starts at 3 minutes and is counted down until the time is 0. The safety stop timer disappears and NDL appears in its place once the timer reaches zero.

The timer stops temporarily if the depth becomes equal to or more than 26.5 feet (8.1m) during which time the counter stops temporarily, and the NDL display appears again.

The timer is reset if the depth becomes equal to or more than 33 feet (10 m).

If the diver doesn't follow the safety stop information the IQ-700 doesn't impose any penalty.

Out of measurement range condition (Fig. 33)

When exceeding a measurement range, the exceeded parameter becomes '---' display and all of the displays blink. The following situations will cause an Out of Measurement Range condition.

Case 1: the water depth exceeds 328 ft(99.9m).

Case 2: the dive time exceeds 599 minutes.

Case 3: decompression is required at a decompression stop depth greater than 30 meters (100 feet).

Case 4: decompression stop time has exceeded 99 minutes

Case 5: total ascent time has exceeded 99 minutes

Ex. water depth exceeded a measurement range

The water depth exceeds the measurement range over 328 ft (99.9m)

Fig. 33

During an Out of Measurement condition the entire display blinks.

Changing the Nitrox mix during the dive (Fig. 31, 32)

By pushing and holding the A button the diver can switch the Nitrox mix that was set in the dive set mode.

How to switch the Nitrox mix during a dive:

When Button A is pressed the PO_2 display changes to the currently set oxygen ratio and blinks twice. When Button A is pressed and held for four or five seconds, the MIX setting is switched. Once this setting is changed, the back light goes on for 3-4 seconds and the modified oxygen ratio is displayed for 3-4 seconds. If the modified setting was for MIX1, then the display switches to MIX2, or if it was MIX2 the display switches to MIX1. If the PO_2 of the new mix is equal to or more than 1.6 the IQ-700 will not allow the mix to be changed. Also, if the MIX2 is ‘—’%, it will not change.

WARNING

Do not use your IQ-700 without confirming that its FO2 setting accurately matches that of your breathing media. Failure to do so may mean that your IQ-700 will be unable to accurately monitor your exposure to nitrogen and oxygen, and lead to decompression illness (DCI) or CNS Oxygen Toxicity, conditions that can cause serious person injury or death.

C button

When the user pushes and holds button C, it displays the temperature, the dive time, the maximum water depth and setting FO_2 value.

Display Description during Dive mode

• Current depth: This indicates the current water depth. The water depth is measured underwater every 1 second. If depth is over 328 feet (99.9m) the display is ‘---’. In Gage Mode, if the depth is over 656 feet (199.9m) the display is ‘---’. (Fig. 27)

18. Battery Replacement

In order to replace the battery remove the clear cover with a coin by unscrewing it in the “open” direction indicated by an arrow on the cover. Remove the battery and inspect the compartment for signs of corrosion or water. If you find signs of corrosion return the computer to your authorized TUSA dealer.

Replace the old battery with a new one, taking care that the polarity is correct. Failure to do so may result in the computer losing its calibration. Inspect and lubricate the battery compartment cover O-ring with a thin film of silicone grease before replacing it.

Screw the cover back in place in the direction indicated on the cover. Do not over tighten.

Please note that the warranty does not cover damage to the computer due to improper battery replacement.

19. Units of Measurement

You can change the units of measurement for water depth and temperature of the IQ-700.

In Dive Set mode press and hold down both the A and C button for six or more seconds. The computer will beep once to tell you that the system has changed.

Always verify the units of measure are correct before starting to dive.

20. General Handling

Do not store the computer in hot and/or humid environments. The pressure transducer is sensitive to both heat and humidity. If impaired, it may cause display of incorrect altitude or depth data.

The IQ-700's liquid Crystal Display may darken if left in a hot environment (such as on a car's dashboard). It will return to normal once allowed to cool; however extensive exposure to heat may shorten LCD life.

Other than for battery replacement, following the procedures outlined in this manual, the IQ-700 is not to be disassembled by anyone other than TUSA or its authorized dealers. Unauthorized disassembly will violate the warranty.

If the IQ-700 does not appear to be functioning properly, in any manner, do not use it to dive. Return it to your authorized TUSA dealer for repair.

Rinse the IQ-700 thoroughly in fresh water following every dive.

Do not use cleansers, chemicals, or solvents to clean the IQ-700. Use a soft cloth to gently wipe dirt or water stains from the screen.

Store the IQ-700 in a clean, dry location. After diving, wipe the computer dry and store it in a location separate from other damp items.
