Introduction
Thank you for your purchase of this Citizen CYBER AQUALAND Nx. Please make sure to
read this manual carefully before using your watch to ensure that it is used properly.
Furthermore, store this manual in a safe place for future reference as necessary.
CYBER AQUALAND Nx is a divers watch equipped with its own depth gauge, and
features an internal dive computer compatible with both NITROX and high-altitude diving.
The watch automatically stores various data (including maximum depth, dive time and
other parameters) as well as diving profile data during diving, and displays that data in the
form of log data.
Diving data stored in the watch can be loaded into a personal computer using an infrared
communication interface or separately sold communication unit (USB interface) by
installing AQUALAND GRAPH Nx in your personal computer from the CD-ROM disc
provided.
Once diving data has been loaded into your personal computer, you can enter characters,
generate graphs of diving data or paste still images or animated data, and manage them
collectively in the form of a daily log. Since the daily log can be printed out or converted to
an HTML format, it offers considerable convenience in storing diving records.
In addition, installing the CAPgm software provided with the watch not only lets you set
various functions of the watch (travel time, alarm time, timer setting and so forth) on your
personal computer, but also lets you display your favorite graphic on the watch display on
different days of the week.
We hope that the use of your CYBER AQUALAND Nx will let you get more enjoyment
from your diving.

This mark indicates prohibited matters.
WARNING
Read this manual carefully and pay attention to all dangers, warnings
and cautions. 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.
5
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.
General Cautions Regarding Diving
WARNING
In the case of using this watch for diving, always make sure to receive the
proper scuba diving training from a certified instructor so that you have the
necessary experience and skills required for safe diving. In addition, make
sure that you have completely mastered the handling and operation of this
watch.
Even though you may only be engaged in recreational diving, any type of diving can
be potentially dangerous. Attempting to engage in diving with improper or inadequate
training can result in a fatal or serious accident.
WARNING
Never attempt NITROX diving unless you have received special training for
NITROX diving.
Although this watch is also compatible with NITROX diving, NITROX diving presents
serious or potentially fatal risks unlike ordinary diving using compressed air.
WARNING
Each diver should be responsible for formulating and executing a diving
plan to ensure safety that matches his or her own abilities.
The dive computer function of this watch is not designed to completely prevent the
occurrence of decompression sickness. In addition, it is unable to monitor differences
in the physiological functions of individual divers or differences in physical condition
on a particular day. Since physical condition has a considerable effect on the
occurrence of decompression sickness, the degree of the risk of decompression
sickness varies depending on the physical condition of the diver on that day. It is
therefore recommended to avoid diving when physical condition is poor, such as in
the case of illness, fatigue, lack of sleep or hangover.
6
Cautions Regarding Use of this Watch
DANGER
Do not use this watch during decompression diving, especially during
NITROX diving.
Although this watch will provide data on decompression diving in an emergency,
using this watch for decompression diving entails risks. Since decompression diving
during NITROX diving in particular is very dangerous, never use this watch under
these conditions. Decompression diving during NITROX diving can lead to an
accident causing death or serious injury. (The DCIEM algorithm generates a
particularly hard error in the case of decompression diving during NITROX diving.)
DANGER
Never loan or share the watch with another person when resting on the
surface (while the watch is operating in the surface mode). In addition, do
not use the data displayed by the watch as the data for a person other than
the user.
This watch is designed on the premise of use by a single user.
Since calculations made by the dive computer based on previous diving are continued
to be used during operation in the surface mode, use of the watch by another person
can prevent the dive computer from making calculations suitable for the user,
resulting in the risk of an accident causing death or serious injury.
DANGER
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.
WARNING
In the case of using this watch for diving, always make sure to also use
other backup equipment (including a DCIEM dive table, divers watch,
residual pressure gauge and water depth gauge).
Sudden fluctuations in the atmosphere and changes in water temperature may have
an effect on the display and performance of the watch. Always make sure to use this
watch in combination with other backup instruments in case the watch should happen
to malfunction. The dive computer functions of this watch are not intended to
completely protect you from decompression sickness and oxygen toxication. Since
the watch is only intended to display information to serve as a reference for
minimizing the risk of decompression sickness and so forth, it is not intended to
completely ensure the safety of the user.
7
WARNING
Always make sure to inspect all functions of the watch prior to each dive to
prevent malfunction of the watch and accidents caused by use of the watch
at improper settings. (Refer to the section entitled, “Cautions Regarding
Use During Diving” (p. 17), for information on the inspection procedure.) In
particular, always make sure to check whether the watch is sufficiently
charged, whether the oxygen concentration (O2%) is set correctly, and
whether there are warnings being displayed.
WARNING
Diving when using this watch is limited to recreational diving at a water
temperature from +10°C to +40°C (50°F to 104°F).
Do not use this watch for saturation diving using helium gas, diving at a water
temperature outside the above temperature range or high-altitude diving at 3,000 m
(10,000 ft) above sea level or higher since this can prevent the watch from functioning
properly or lead to an accident resulting in danger. In addition, this watch does not
display depth properly when used in water other than seawater (specific gravity of
1.025).
WARNING
In order to ensure safe diving, dive while allowing an adequate margin of
safety relative to the displayed no-decompression limit time.
WARNING
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.
Since decompression diving is associated with a high risk of decompression sickness,
observe the following matters at all times.
• 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.
• 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.
8
WARNING
Skin diving after scuba diving is not recommended since it can have a
serious effect on your health. 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).
CAUTION
Data Storage
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. 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.

Cautions Regarding Use During Diving
WARNING
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.
Failure to observe these matters can lead to decompression sickness,
oxygen toxication or other accidents involving death or serious injury.
* Please refer to these matters along with the section describing “Safety Precautions”
on pp. 7-11 for further details.
• In the case of using this watch for diving, always make sure to also use other
backup equipment (including a DCIEM dive table, divers watch, residual pressure
gauge and water depth gauge) to ensure safety.
• 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 nodecompression 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 water depth outside the guaranteed temperature range or at an
altitude of 3,000 m (10,000 ft) or higher
··· The temperature range for which the water depth measurement accuracy of this
watch is guaranteed is from +10°C to +40°C (50°F to 104°F).
··· The water depth measurement function does not operate at high altitudes
equivalent to 3,000 m (10,000 ft) above sea level or higher.
• 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.
15
Cautions Regarding Use During Diving
Please make sure to observe the following matters before, during and after diving.
WARNING
Cautions Before 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.
• During NITROX diving, check that the oxygen concentration (O2%) is correctly set to
the oxygen concentration of the tank actually used before each dive. Diving with the
oxygen concentration set incorrectly may cause incorrect information to be displayed
during diving, greatly increasing the risk of decompression sickness and oxygen
toxication. The oxygen concentration (O2%) cannot be set or changed while in the
water and after a dive has been started. Always make sure to check and set the
oxygen concentration prior to diving.
• Check whether “ERR (Error)”, “CHK (Check)” or “CHRG (Charge)” is displayed on
the display. The watch will not switch to the dive mode when “ERR” or “CHK” are
displayed. If “CHRG (Charge)” is displayed, since this indicates that the watch is not
fully charged, the watch may become insufficiently charged while diving.
• 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.
• When there is a large difference between the temperature of the watch and the
water temperature, immerse the watch in the water for at least 5 minutes to
acclimate the temperature of the watch to the water temperature and then remove it
from the water before diving. A large difference between the watch temperature and
water temperature (such as in the case of placing the watch in water having after
allowed it to sit in direct sunlight) can prevent water depth from being measured
accurately.
WARNING
Cautions During Diving
• Avoid ascending too rapidly. A rapid ascent 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.
16
WARNING
Cautions After Diving
• Make sure to rest sufficiently after diving by referring to 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
Diving in Fresh Water
• Although this watch is compatible with high-altitude diving, since it is ultimately
designed on the premise of diving in seawater, it does not display the correct water
depth if used in water other than seawater.
• Only use this watch for diving in fresh water after having received special safety
training. Since this watch displays water depth by converting on the basis of
seawater (specific gravity: 1.025), the water depth is actually 2.5% deeper than the
displayed depth.
Example: Displayed water depth of 20 m M 1.025 = 20.5 m (actual water depth)
(66 ft M 1.025 = 68 ft)
* Although an error occurs in the displayed water depth during freshwater diving at high altitudes
and so forth, the calculations of the dive computer are performed correctly.
17
Features
This watch is provided with numerous convenient
functions used during diving.
L
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).
* Decompression Calculation Algorithm
This watch employs the calculation formula of the Canadian Defense and Civil Institute of
Environmental Medicine (DCIEM).
L
This watch is compatible with NITROX diving (NITROX: mixed gas having an oxygen
concentration that differs from compressed air used in ordinary diving) and high-altitude
diving.
• The oxygen concentration (O2%) of the mixed gas can be set within the range of 22% to 50%.
• Since the pressure sensor periodically measures air pressure even when on land and
calculates the body’s nitrogen level each time, decompression calculations are performed
corresponding to altitude based on actual air pressure prior to diving during high-altitude
diving as well.
Measurement of water depth begins automatically simply by placing the watch on your
wrist and entering the water, and various data (depth, elapsed time, etc.) are measured
automatically while diving.
L This watch distinguishes between skin diving and scuba diving according to diving
conditions (depth and dive time), and a maximum of 100 sets of log data are
automatically recorded for both types of diving.
L This watch is also provided with various warning functions necessary for safe diving.
L Log data and profile data (up to 2 hours) automatically recorded in the watch can be
transferred to a PC by using the infrared communication interface or communication
unit*1 , making it possible to easily manage and generate graphic representations of
transferred data on your PC.
L
Various watch functions can be set on your PC.
L
The following watch settings can be transferred to and edited on your PC using the
infrared communication interface or communication unit*1 .
• Addition, deletion and alteration of locations displayed in each mode by the watch.
• Various travel time, alarm and destination timer settings.
• Setting of dive alarm used during diving and entry of the number of previous dives.
• Setting of daily graphics and graphics displayed on anniversaries (graphic display).
This watch is also equipped with an infrared
communication function.
The wrist watch infrared communication standard (IrWW) is used for infrared
communication. This enables the time and alarm time to be set between watches using
this standard.

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.

Charge level
indicator
The charge level indicator provides a general reference for
determining the amount of charge remaining in the watch.
In addition, it also indicates whether or not each function
can be operated ("OK" or "NG") at the current charge level.
In case of insufficient power it will display "NG", however if
the watch has sufficient power for a function, it will display
"OK", and that function can be operated. The
indicates that a function can be operated, but
additional charging is recommended.
* Please refer to “Charge Level Indicator and Continuous Usage Time” for information on a general
indicator of the amount of charge.
G.C.: Garbage Collection
This indicates whether or not the garbage collection operation can be performed.
* This watch uses flash memory to store the various settings and diving data of the watch edited
with a personal computer. Whenever new data is recorded in flash memory, areas of memory
that are no longer used as well as areas of memory in the gaps between data are generated in
the flash memory. Garbage collection refers to an operation that creates continuous areas of
available memory so that these areas can be reused automatically.
43
: Diving Function
This indicates whether or not the watch can be used for diving.
• The
display means that the watch is insufficiently charged for use during diving.
Although the dive mode continues to operate even in this state, if diving is performed while in
this state, the watch may become insufficiently charged during diving. Sufficient charge the
watch prior to diving to ensure safety.
• When "NG" is displayed, the watch will not switch to the dive mode. The watch can therefore
not be used for diving in this state.
Ir: Infrared Communication Function
This indicates whether or not the infrared communication function can be used for data transfer
with a personal computer or between watches.
C. Flash Memory Status Display
This display provides a general indication of the amount of flash memory available. In
addition, garbage collection can also be performed during this display by pressing one of
the buttons.
<Reading the Bar Graph>

into available memory by performing garbage collection.
b: Gray segment: Area currently used by files.
a
/This segment becomes larger the greater the amount of
diving data, daily graphic data and so forth.
c: White segment: Area of available memory.
D. Garbage Collection Operating Procedure
Garbage collection begins when the upper left button (C) is pressed for at least 2 seconds
and then released during the flash memory status display.
• During the garbage collection operation, an alarm sounds and "G.C." is displayed on the
display. When garbage collection is completed, "Done" is displayed on the display.
• Garbage collection cannot be performed when "G.C." has changed to "NG" on the
charge level indicator. "Fail" is displayed on the display at this time.
<General Reference for Performing Garbage Collection>
Try to perform garbage collection when the black segment on the flash memory status display is
larger than the white segment (available memory). Garbage collection consumes considerable
power. For this reason as well, in order to ensure that flash memory is used efficiently, it is
recommended to perform garbage collection whenever the watch is charged (fully charged).
44
* If “Error” appears on the display or “G.C.” remains displayed during garbage collection, there
may be a problem in the flash memory. In this case, after formatting flash memory while
referring to “Formatting Flash Memory”, try repeating the garbage collection procedure. If
“Error” is still displayed, the watch may have a malfunction. Please request that the watch be
repaired at the Citizen Service Center.
* Garbage collection is only performed to organize the contents of flash memory. There is no risk
of deleting watch settings or diving logs as a result of performing garbage collection.

Warning Functions
This watch is equipped with various warning functions for the purpose of avoiding risks and
problems when diving as much as possible.
WARNING
* 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.
CAUTION
If a warning alarm sounds during diving, first begin to ascend to a shallow depth at
an ascent rate of no more than 18 m (60 ft)/min to ensure safety.
Since the risk involved increases as you dive to greater depths, multiple alarms may
continue simultaneously, causing multiple warning alarms to sound.

2. Explanation of Warning Functions
Insufficient Charge Warning
When the watch becomes insufficiently charged, "BATT" flashes in
the lower left corner of the display in all of the 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
Flashing
sensor gets wet. (The watch automatically switches to the charge
level indicator display of the system monitor mode when the water sensor 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
charger 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 after “BATT” has started flashing.
Promptly begin to ascend it this warning function is activated during diving.
* If the watch remains insufficiently 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
modes of the standard mode as well as in the dive mode. The
watch automatically switches to the flash memory status display of
Flashing
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 diving.
The file error warning 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.
48
Abnormal Pressure Detection Error Warning
When abnormal atmosphere pressure is detected during use on land, or
when ascending to high locations more than 3,000 m (10,000 ft) above
sea level, "ERR" (Error) flashes in the lower left corner of the display.
The watch does not switch to the dive mode even if the water sensor
gets wet while this warning function is activated.
Flashing
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.
Flashing
* "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 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
illustration of a turtle are displayed at the bottom of the display.
The ascent rate warning alarm stops sounding when a proper
ascent 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 (4 ft) 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 corner of the display.
Once "ERR" has been displayed during diving, it continues to be
displayed until the dive mode is terminated.
Flashing
CAUTION
Avoid using this watch in environments subject to sudden changes in water
pressure such as when using ocean floor excavation or similar equipment.
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 correctly.
49
Exceed Maximum Depth Warning
When the limit depth of 40 m (131 ft) for recreational diving is
surpassed during the course of diving, an exceed maximum depth error
occurs, the current depth flashes and the alarm sounds for 15 seconds.
During diving at a depth greater than 40 m (131 ft), the warning alarm
sounds for 15 seconds every minute.
This warning function is canceled when the depth returns to 40 m
(131 ft) or less.
Flashing
Decompression Diving Warning
This alarm sounds for 3 seconds and the decompression stop indicator
(STOP) is displayed on the display when the no-decompression limit
time has been exceeded resulting in decompression diving during the
course of diving.
The display returns to the no-decompression diving display when
decompression stop is performed in accordance the
decompression stop instructions.
Decompression Diving Error
When decompression diving takes place beyond the no-decompression
limit time during diving in the NITROX setting, together with the alarm
sounding for 1 second and the decompression stop indicator (STOP)
being displayed on the display, the instructed depth and instructed time
flash. During a decompression diving error, the instructed depth and
instructed time continue to flash, and the alarm sounds for 15 seconds
every minute.
Flashing
Ascend to a shallow depth at a safe ascent rate as soon as possible. The display returns
to the no-decompression diving display when a decompression stop is performed in
accordance with the decompression stop instructions.
Permanent Error Warning
The instructed depth flashes and an alarm sounds continuously when
either of conditions 1 or 2 below are met. If hazardous diving or
ascending is continued while ignoring this warning, a permanent error
(ERROR) occurs:
1. When not ascending to the instructed depth and continuing to dive at
an excessively low depth (diving at which the instructed
decompression stop depth exceeds 9 m (30 ft).) even though having
been instructed to make a decompression stop (Permanent Error
Warning 1).
Flashing
The warning stops when the diver begins to ascend immediately and the
decompression stop instructed depth reaches 9 m (30 ft) or less.
2. When having ascended to a depth 1 m (4 ft) or more less than the instructed depth after
having been instructed to make a decompression stop (Permanent Error Warning 2).
In this case, the warning is canceled when the diver returns to the instructed depth.
50
Permanent Error
If hazardous diving or ascending is continued even after the permanent
error warning function has been activated, a permanent error results,
"ERROR" appears on the display and the entire display flashes.
When a permanent error has occurred, the next dive cannot be made
for 24 hours. (The water depth measurement function does not operate
for 24 hours. In addition, "ERROR" is displayed when the watch is
switched to the dive plan mode, and the no-decompression limit time is
not displayed.)
Flashing
Flashing
PO2 Limit Warning
PO2 flashes to warn that the PO2 limit is approaching at the depth where
PO2 (body partial pressure of oxygen) reaches 1.4 during diving in the
NITROX setting.
The alarm stops when you ascend to a shallow depth and PO2 falls
below 1.4.
PO2 limit Error
Flashing
An alarm sounds for 15 seconds every minute in addition to PO2
flashing display when PO2 exceeds the limit of 1.6 as a result of not
ascending to a shallow depth even after the PO2 limit warning has been
activated.
The error is canceled and the display returns to the PO2 limit
warning display when you ascend to a shallow depth and PO2 falls
below 1.6.
Oxygen Toxication Time Warning
Flashing
When the amount of time remaining until the oxygen toxication time
(OTT) decreases to less than 10 minutes during diving in the NITROX
setting, the display in the upper right corner of the display changes from
no-decompression limit time (NDL) to remaining OTT time (flashing). In
the case of decompression diving, remaining OTT time flashes instead
of the total ascent time in the upper right corner of the display.
The warning stops if you ascend to a shallow depth and the
remaining OTT time returns to 10 minutes or more.
Oxygen Toxication Time Error
Flashing
If the remaining OTT time reaches 0 minutes as a result of not
ascending to a shallow depth even after the oxygen toxication time
warning has been activated, an oxygen toxication error occurs, and in
addition to “0’ ” flashing for the remaining OTT time, the alarm sounds
for 15 seconds every minute.
The error is canceled and the display returns to the oxygen
toxication time warning state when you ascend to a shallow depth
and the remaining OTT time increases.
51
Diving 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
<No-Decompression Diving and No-Decompression Limit (NDL) Time>
No-decompression diving (NDL = No-Decompression Limit) 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.
<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).
<NITROX Diving>
NITROX diving refers to diving in which a mixed gas of oxygen and nitrogen is used that has a
higher oxygen concentration than ordinary air tanks. This watch allows the oxygen
concentration (O2%) to be set within the range of 22% to 50% in the dive plan mode.
* NITROX diving reduces the diver’s risk of decompression sickness by reducing the nitrogen ratio (%) to a
level lower than ordinary AIR diving. However, increasing the oxygen ratio (%) also invites the risk of
“oxygen toxication” for the diver, a condition that is unpredictable in the case of AIR diving. In the case of
performing NITROX diving, always make sure to receive safety training relating to NITROX diving in
advance.
<AIR Diving>
AIR diving refers to diving using an ordinary air tank (compressed air having an oxygen
concentration of 21%). This watch uses the term AIR diving to distinguish it from NITROX
diving in which the oxygen concentration is 22% or higher.
<High-Altitude Diving and Altitude Setting>
High-altitude diving refers to diving at a high altitude of 300 m (1,000 ft) or more above sea level
(such as in lakes, ponds or rivers). Since this watch calculates no-decompression time when
diving by calculating body nitrogen level based on actual atmospheric pressure periodically
measured while on land prior to diving, special settings are not required during high-altitude
diving. However, water depth is displayed based on seawater (specific gravity: 1.025) even
when diving in fresh water.
* Since atmospheric pressure at high altitudes differs from that at lower altitudes where ordinary diving is
performed, high-altitude diving requires special skills. In the case of performing high-altitude diving, always
make sure to receive safety training regarding high-altitude diving in advance.
52
<Repetitive Diving>
Repetitive diving refers to diving that is repeated while there is still residual nitrogen in the body
from the previous dive. The number of the next dive for repetitive diving is displayed on the
second display of the dive plan mode.
<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.
<Safety 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.
<Total Ascent 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.I. Time as referred to in the scuba diving 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.
53
<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 ft). 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.
<Oxygen Concentration (O2%)>
This refers to the ratio (%) of oxygen in the tank used for diving. During NITROX diving,
always make sure to set the oxygen concentration according to the oxygen concentration
of the tank actually used in the dive plan mode. The oxygen concentration (O2%) can be
set within a range of 22% to 50%.
<Oxygen Toxication>
This refers to a rejection reaction (consisting of symptoms such as dizziness, nausea and
paralysis) that occurs due to the infusion of large amounts of oxygen into the human body.
This condition can be fatal in extreme circumstances.
<Partial Pressure of Oxygen in the Body (PO2)>
The partial pressure of oxygen in the body (PO2) refers to the absolute pressure (ATA) of
oxygen that acts within the body. The partial pressure of oxygen in the body is determined
by the NITROX oxygen concentration and depth, and increases as depth becomes
deeper. In general, the limit at which oxygen toxication occurs in the human body is said
to be PO2 = 1.6 (ATA). The display of this watch flashes when PO2 is between 1.4 and
1.5, and when PO2 reaches 1.6 or higher, an alarm sounds to warn the diver.
<Oxygen Toxication Time (OTT)>
Oxygen toxication time (OTT) refers to the limit time of oxygen toxication. The oxygen
toxication time is determined by the NITROX oxygen concentration, depth and dive time.
In this watch, when the amount of time remaining until oxygen toxication time decreases to
less than 10 minutes, the amount of time remaining until OTT flashes on the display, and
when the oxygen toxication time reaches 0 minutes, an alarm sounds to warn the diver.
54
Using the Dive Plan Mode
This mode is used to set the plan for the next dive. The dive plan mode uses the three
displays described below.
• Dive Condition Display: This lets you change between AIR diving and NITROX diving and
set the oxygen concentration (O2%). Continuously displays the
current settings.
• Dive Plan Display:
This lets you display the number of the next dive for repetitive diving,
a graph of the body nitrogen level, and the no-decompression limit
time corresponding to initial and repetitive diving.
• Dive Alarm Display: This lets you display and set the depth alarm and dive time alarm.
1. Switching the Display
The display changes each time the lower right button (A) is pressed once in the dive plan
mode. The displayed contents differ between when the watch is set to AIR and when it is
set to NITROX diving.

* If none of the buttons are pressed for about 3 minutes during each of the displays of the dive plan
mode, the watch automatically returns to the time mode of the standard mode.
* The dive condition mark of the dive plan display changes to the high altitude mark in environments at
an air pressure equivalent to high-altitude diving.
2. NITROX Setting
The NITROX setting is for use when diving with a mixed gas having an oxygen concentration
that differs from that of air tanks used for ordinary diving (oxygen concentration: 21%). Set the
watch to AIR for all other types of diving. The watch will return to the AIR dive mode
automatically after 6 hours have elpased without diving, or, 30 minutes have elpased during
surface interval time after NITROX diving.
DANGER
Always double check the oxygen concentration (O2%) before each and every NITROX
dive.
It is very important to ensure that the percentage of oxygen carried in your tank, maches
the setting of the watch exactly. Failure to comply with this instruction may result in
decompression sickness, oxgen toxication or death .
The oxygen concentration (O2%) setting cannot be changed whilst diving, therfore always
check that the correct O2% is set before diving.
3. High-Altitude Setting
Since air pressure decreases at high altitudes, it is necessary to take this change in air pressure
into consideration when calculating the body partial pressure of oxygen. This watch periodically
measures air pressure and then calculates the body partial pressure of oxygen each time based
on the measured air pressure, thereby eliminating the need to manually set the watch for high
altitudes. In environments where air pressure is low, the watch automatically judges the
environment to be a high-altitude environment, and the dive condition mark changes to the high
altitude mark (
or
). The altitude at which the dive condition mark changes to the high
altitude mark is about 300 m (1,000 ft) above sea level.
CAUTION
The high altitude mark is only intended to serve as a general indicator of high altitude.
There may be times when the dive condition mark does not change to the high altitude
mark even at altitudes above 300 m (1,000 ft) above sea level, or times when the dive
condition mark changes to the high altitude mark even though the watch is at a low altitude
below 300 m (1,000 ft) above sea level. In any case, the watch can still be used without
risk since the dive computer calculates the body partial pressure of oxygen corresponding
to the air pressure at that time.
56
4. Dive Condition Marks
The dive condition currently set for each of the time modes of the standard mode, the dive plan
display in the dive plan mode and the surface mode is displayed using one of the four types of
marks indicated below.
• Identification of the AIR or NITROX setting for the next dive set in the dive plan mode
• Identification of high-altitude diving automatically set according to the air pressure measured
by the pressure sensor

(display flashing), the flashing oxygen concentration setting is finalized automatically and the watch
changes to the NITROX setting display.
* In the case of changing the oxygen concentration setting after it has been set, reset the oxygen
concentration after first returning to the “AIR” setting display.
B. Switching from NITROX Setting to AIR Setting
After about 30 minutes have elapsed for surface interval time after having performed scuba diving
in the “NITROX” setting, an alarm sounds and the watch automatically returns to the “AIR” setting.
In addition, if scuba diving is not performed for about 6 hours after having set the watch to
NITROX, the watch automatically returns to the “AIR” setting. In the case of returning to the “AIR”
setting after having set the watch to “NITROX”, return the watch to the “AIR” setting by pressing
the upper left button (C) for 2 seconds or more and then releasing during the “NITROX” display.

Using the Scuba Diving Log Mode and Skin Diving Log Mode
The scuba diving log mode is used to display the scuba diving log automatically recorded
by the watch during scuba diving. The skin diving log mode is used to display the skin
diving log automatically recorded by the watch during skin diving. A maximum of 100 sets
of log data can be recorded for both scuba diving and skin diving (provided that the dive
time of a single dive is within 2 hours and no more than 15 dives per day). The contents
of log data for a single dive are displayed using three displays for both the scuba diving
log and skin diving log modes.
1. Calling Up Scuba Diving Log Data
(1) The most recent scuba diving log data is displayed when the watch is switched to the
scuba diving log mode by pressing the lower left button (D).
(2) The log data that you want to view can be selected by pressing either the lower right
button (A) or upper right button (B). Logs are identified according to the number of the
dive (No.) among the total number of dives.

* Calling up log data may take some time when there is a large amount of log data recorded. In
such cases, "WAIT" is displayed while log data is being called up. The water sensor and none
of the button operations function while "WAIT" is displayed.
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.
62
Using the Dive Mode
This mode measures water depth while in the water. The watch automatically switches to the
dive mode when the water sensor detects water in any mode except for the infrared
communication mode and power save mode. The watch automatically begins to measure water
depth when the water depth reaches 1 m (4 ft) or more during the preliminary dive display.
During diving, the dive computer performs calculations corresponding to the set dive condition,
and displays information required by the diver, including the current depth, dive time and
maximum depth.

• During the preliminary dive display, the diver mark flashes in the lower left corner of the display
and the display of each mode prior to switching to the preliminary dive display is maintained.
• Once measurement of water depth begins, if diving continues for more than 3 minutes at a
depth of more than 1 m (4 ft), the watch switches to the scuba diving display and displays nodecompression limit time.
• The diver mark flashes in the lower left corner of the display while diving.
DANGER
During NITROX diving, always make sure to check that the oxygen concentration
(O2%) is correctly set to the oxygen concentration of the tank actually used prior to
diving.
Oxygen concentration (O2%) cannot be set or changed while in the water or after starting a
dive. Always make sure to set oxygen concentration prior to diving.
WARNING
Before starting a dive, always make sure to check that the “Diver Mark” is flashing in
the lower left corner of the display during the preliminary dive display.
The water depth measurement function will not operate if “BATT”, “ERR” or “CHK” is
flashing in the lower left corner of the display during the preliminary dive display (indicating
that a warning function has been activated). In the state in which “CHRG” (Charge) is
displayed, the watch may become insufficiently charged while diving. In addition, even if
the insufficient charge warning function (“BATT” is displayed) has not been activated, to
avoid the watch becoming insufficiently charged while diving, start the dive after first
sufficiently charging the watch.
* Refer to “Warning Functions” for further details.
63
1. Explanation of Display During Water Depth Measurement
The display during diving differs between the AIR setting (air diving) and NITROX setting
(NITROX diving). Even in the case of performing scuba diving, the watch displays the skin
diving display until 3 minutes or more have elapsed continuously at a depth of 1 m (4 ft) or
more.

65
DANGER
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.
2. Safety Stop Graph and Decompression Stop Graph
A. Safety Stop Graph Display
A graph serving as a general reference for changes in depth during safety stop and the
elapsed time during a safety stop are displayed after having descended to a depth of more
than 5 m (15 ft) and then ascended to a depth of 5 m (15 ft) during scuba diving (nodecompression diving).

3. Depth Measurement
This watch measures depth every second, and continuously displays the current depth in
0.1 m (0.3 ft) units during the course of diving.
• Measuring range: 1 m to 80 m (4 ft to 266 ft)
* 0 m (0 ft) is displayed at depths of less than 1 m (4 ft), while - -.- m is 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 alternately displayed until that dive is completed.
66
4. 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 ft). 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
5. Water Temperature Measurement
The watch begins to measure water temperature one minute after the water depth reaches
a depth greater than 1.0 m (4 ft), and the most recently measured water temperature is
continuously displayed in 1°C (1°F) units at 1 minute intervals while diving. However,
water temperature is only displayed when the lower right button (A) is pressed during
decompression diving. (Water temperature measured in 0.1°C units rounded and
displayed 1°C (1°F) units.)
• Measuring range: -9.4°C to +40.0°C (15°F to 104°F)
6. No. of Dives Per Day and Recording Log Data
A maximum of 15 dives of log data can be recorded per 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.
In case the number of dives per day for skin diving exceeds 15, and the number of dives
per day for scuda diving is 14 or less, "FILE" mark is displayed for the first 3 minutes on
the watch display. But scuba diving log is held properly. After 3 minutes, the watch display
automatically changes to scuba diving instead of skin diving, then "FILE" mark disappears.
7. Ending the Dive Mode
• The watch returns to the surface mode or the time mode of the standard mode when the
lower left button (D) is pressed for at least 2 seconds and then released when 0 m (0 ft)
is displayed after completion of a dive.
• The watch automatically returns to the surface mode or time mode of the standard mode
after roughly 10 minutes have elapsed since 0 m (0 ft) is displayed following water depth
measurement.
<0 m (0 ft) Display After AIR Diving>
<0 m (0 ft) Display After NITROX Diving>
67
Using the Surface Mode
The surface mode is used to display elapsed time from the end of the most recent scuba
dive (S.I. time) and the amount of time remaining until boarding an aircraft is permitted (no
fly time).
DANGER
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.

Low power mode (Temporary function)
The low power mode is a special mode for allowing the watch to run while using the
minimum amount of current consumption. When the watch becomes insufficiently
charged, it automatically switches to this mode to conserve current consumption. In
addition, the watch can be manually switched to the low power mode by pressing the
lower right button (A) and lower left button (D) simultaneously for at least 2 seconds and
then releasing in the time mode of the standard mode.
* Since all functions except for the time/date display and correction functions do not operate in the
low power mode, do not use this mode when using (wearing) the watch under normal
circumstances.
1. Switching the Display
• The time and date displays switch back and forth each time the lower right button (A) is
pressed once.
• The entire display goes out (no display) when the lower left button (D) is pressed for at
least 2 seconds and then released during the time display or date display. Pressing the
lower left button (D) again for at least 2 seconds and then releasing returns the watch to
the time display.
• The watch returns to the time mode of the standard mode (or to the surface mode when
the surface mode has been activated) when the lower right button (A) and lower left
button (D) are pressed simultaneously for at least 2 seconds and then released during
the time display or date display.

Data Communication Functions
Data is transferred between watches or between the watch and personal computer using
the data communication functions. There are two ways for transferring data: the first
involves using the infrared communication interface, and the second involves using the
communication unit (USB communication interface) function.
1. Infrared Communication
The infrared communication function of this watch uses an infrared (Ir) beam for
communication in the same manner as the remote controllers of television sets and VCRs.
Communication is performed between watches or between the watch and a personal
computer by transmission and reception of this infrared beam by their respective infrared
transmission/reception units.
* The infrared communication function of this watch complies with the wrist watch infrared
communication standard IrWW (IrDA for Wrist Watches).
A. Communication Range
The maximum distance infrared communication can be
performed with this watch is 15 cm (5.9 inch) in the
vertical direction to the infrared transmission/reception
unit. Although directivity has a margin of about ±15°, the
communication distance becomes shorter as the angle

CAUTION
• In order to maintain water resistance performance, have your watch inspected at a Citizen
Service Center every one to two years, and have the gaskets, crystal or other components
replaced as necessary.
• If moisture has entered the watch, or if the inside of the glass is fogged up and does not
become clear for an extended period of time, do not leave the watch in that state, but
immediately take the watch to a Citizen Service Center for inspection and repair.
• If sea water enters the watch, place the watch in a box or plastic bag, and immediately take it
in for repair. Otherwise, pressure inside the watch will increase and parts (such as the glass
and buttons) may come off.
WARNING
Handling of Energy Storage Cell
• Do not attempt to remove the energy storage cell from the watch. If the energy storage cell
must be unavoidably removed, place it in a location out of the reach of children to prevent
accidental swallowing.
• If the energy storage cell is accidentally swallowed, contact a physician immediately and seek
medical attention.
WARNING
Only Use Specified Energy Storage Cell
• Never attempt to use an energy storage cell other than the energy storage cell used by this
watch. Although the structure of the watch prevents the watch from operating if another
battery is installed, if a silver battery or other type of battery is forcibly installed in the watch
and the watch is attempted to be charged with that battery installed, the battery may rupture
resulting in possible damage to the watch and physical injury. Always make sure to use the
specified energy storage cell when replacing.
97
CAUTION
Repairs
All parts of this watch, excluding the band, are to be repaired only at a Citizen Service Center.
Please have all inspections and repairs performed at a Citizen Service Center.
CAUTION
Keep your watch clean
• The case and band of the watch come in direct contact with the skin in the same manner as
clothing. Metal corrosion as well as perspiration, dirt, dust and other unnoticed debris may soil
the cuffs and other parts of your clothing. Try to keep the watch clean at all times.
• Wearing of this watch may cause a rash or itching of the skin in people with sensitive skin or
depending on the wearer’s physical condition. If you notice that you skin is affected by the
watch, immediately stop wearing it and consult a physician.
<Cleaning the Watch>
• Use a soft cloth to wipe off dirt, perspiration and moisture from the case and crystal.
• Rinse off dirt from metal bands, plastic bands or rubber bands with water. Use a soft brush to
remove any dirt or debris stuck between the gaps in metal bands.
• Avoid the use of solvents (such as thinner or benzine) as they may damage the finish.
CAUTION
Precautions When Wearing the Watch
• Be careful while wearing the watch while holding an infant or child, by taking the watch off
beforehand, to prevent injury or other accident.
• Be careful when engaged in vigorous exercise or work to prevent injury and accidents to
yourself and others.
• Never wear the watch in a sauna or other locations where the watch can reach high
temperatures since this can cause burns.
CAUTION
Handling of the Band (Cautions when Putting
on and Taking Off the Watch)
Depending on the structure of the band buckle, be careful not to injure your fingernails when
putting on and taking off the watch.
<Temperatures>
The watch may not function or stop running if exposed to temperatures outside the range of 0°C
to 50°C (32°F to 122°F). In addition, although the liquid crystal display may also become
illegible outside this temperature range, it will return to normal when the watch is returned to
normal temperatures.
• Correct water depth measurement values are not displayed at temperatures outside the range
of +10°C to +40°C (50°F to 104°F).
• Data cannot be transferred outside the range of +10°C to +35°C (50°F to 95°F).
<Static Electricity>
Since the IC used in quartz watches is susceptible to static electricity, the display may become
incorrect if the watch is subjected to intense static electricity like that generated by a television
screen.
98
<Shocks>
Do not subject the watch to violent shocks such as that resulting from being dropped on the floor.
<Chemical Agents, Gases and Mercury>
Avoid using the watch in environments containing chemical agents and gases. If solvents such
as thinner or benzine, as well as articles containing such substances (including gasoline,
fingernail polish, cresol, bathroom cleaners and adhesives) become adhered to the watch, they
can cause discoloration, deterioration and cracking. Use ample caution when handling
chemicals. In addition, contact with mercury used in thermometers and so forth can cause the
case and band to become discolored.
<Storage>
• When not using the watch for an extended period of time, carefully wipe off any perspiration,
dirt or moisture from the watch and store in a location preferably free of high and low
temperatures, high humidity.
