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 diver's 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*):

• If 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

2001.

• 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 CDROM provided for further information regarding the procedures for importing and receiving data.)

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).

This mark indicates that caution or attention is required.

This mark indicates prohibited matters.

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.

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).

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.

Cautions Regarding Use During Diving

WARNING

This watch cannot be used as a primary instrument for diving. When using the watch during diving, always make sure to receive the proper diving instruction and training and use the watch while obeying all rules.

• Inspect the watch to make sure that all functions operate properly before diving.

• It is recommended to only use this watch for recreational diving down to a depth of about

18 m (60 ft). Do not attempt to dive below the limit depth of 40 m (131 ft) during recreational diving.

• Always make sure to allow an ample margin for no-decompression time.

• Perform adequate safety stops and decompression stops. Even in the case of no-

decompression diving, always make a safety stop at 5 m (15 ft) to ensure safety. In addition, in the case the decompression stop display appears, try to stop for a period longer than that indicated on the display.

• Allow for a sufficient rest period after diving in accordance with safety rules. Boarding an airplane or moving to a high altitude without allowing for a sufficient rest period after diving results in the risk of decompression sickness.

PROHIBITED Prohibited Use During Diving

Never attempt to use this watch for diving under the following circumstances.

• When diving is prohibited in the system monitor mode:

··· The watch will not switch to the dive mode when [ ] has changed to NG.

• When the watch has stopped running or an error has occurred (be careful not to bump

the watch against hard objects such as equipment or rocks when diving).

• When measuring depth outside the guaranteed water temperature range or at high altitudes:

··· The temperature range in which the water depth measurement accuracy of this watch

is guaranteed is +10 to +40°C (50°F to 104°F).

··· This watch is not compatible with diving at high altitudes. Never use this watch when

diving at high altitudes (300 m (1000 ft) or more above sea level).

• When engaged in dangerous behavior or when a situation is judged to be dangerous:

··· This watch is not built to function as a preventive or emergency instrument such as for

use during marine accidents.

• When using in a helium gas atmosphere (saturation diving, etc.):

··· Use under these conditions can cause a malfunction or damage to the watch.

• Use for nitrox diving:

··· This watch cannot be used for diving using a mixed gas other than that of air tanks for

ordinary air diving.

WARNING Cautions Regarding Use During Diving

• Sufficiently charge the watch and confirm that the watch is reliably charged and that the watch can be used for diving by referring to the system monitor mode. If the watch is not sufficiently charged, the watch will not switch to the dive mode even if diving is started. 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.

• 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.

• 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.

• 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.

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)

Features

This watch is provided with numerous convenient functions used during diving.

•

Various information is displayed to serve as a reference for safe diving by calculating residual body nitrogen based on depth during diving, dive time and previous dive history, etc. (Dive Computer Function).

An approximate indication of the amount of charge remaining in the secondary battery can be confirmed on the display. The battery charge indicator can be displayed in either the time mode of the standard mode (location display) or the system monitor mode.

1. How to Read the Battey Charge Indicator

The battery charge indicator changes in the manner shown below according to the amount of elapsed time the watch has been used.

2. Continuous Usage Time

This watch will continue to run for about 1 month (until the insufficient charge warning function is activated) once it has been fully charged.

This is roughly based on the conditions of use indicated below.

• Diving (water depth measurement): Twice/week (30 min./dive)

• Alarm: 30 seconds/day

• Chronograph measurement: 1 hour/week

• EL light: 4 seconds/day

* The continuous usage time of the watch becomes shorter the more often the alarm,

chronograph and other functions are used. In addition, the continuous usage time is further reduced by infrared communication.

* Since the water sensor is activated when the watch gets wet even when not diving, the

continuous usage time becomes correspondingly shorter.

All watch functions stop.

The "Insufficient Charge Warning Function (BATT displayed)" is activated at about this time. Charge the watch immediately. (Refer to the section on " Warning Functions" for further details.)

Usage time

Amount of Battery Charge

The watch switches to the "Low power mode" at about this time.

Switching the Mode

• The mode changes in the order of standard mode, dive plan mode, scuba log mode, skin

log mode and surface mode each time button (D) is pressed.

• The sub-mode of the standard mode changes in the order of time, travel time, destination

timer, alarm, chronograph, timer and system monitor each time button (A) is pressed in the standard mode.

• The watch automatically switches to the dive mode (preliminary dive display) when the

water sensor gets wet in any mode (excluding the infrared communication mode and low power mode).

• The watch switches to the infrared communication mode (initial display) when button (D)

is pressed for at least 2 seconds in any mode (excluding the dive mode and low power mode).

* When none of the buttons are pressed for about 3 minutes in any of the modes of the

standard mode, dive plan mode, scuba log mode or skin log mode, the watch automatically returns to the time mode of the standard mode (except that it returns to the surface mode when the surface mode has been activated).

* The watch switches to the low power mode when buttons (A) and (D) are pressed for at least

2 seconds in the time mode of the standard mode.

* If "BATT", "ERR" or "CHK" is flashing in the lower left section of the display in any of the modes

(indicating that a warning function has been activated), and during correction in any mode, the watch does not switch to the dive mode even if the water sensor gets wet.

* The hourglass mark and "LOADING" are displayed when switching to the dive mode, infrared

communication mode or low power mode. The water sensor along with all button operations do not function while these are displayed.

Using the EL Light

The EL light is illuminated for about 1 second when the EL light button on the front of the watch is pressed in any of the modes except for the infrared communication mode. The EL light is illuminated for about 5 seconds when the EL light button is pressed continuously.

CAUTION

Since the display may be difficult to see when confirming the display during night diving, confirm the contents of the display with external lighting such as an underwater light.
