This mark indicates that caution or attention is required.
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.
6
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.
7
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.
8
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 (O
2%) 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.
9
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.

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 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 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.
Cautions Regarding Use During Diving
16
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 (O
2%) 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 (O
2%) 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.
17
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.
18
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.
L
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.
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.
L
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.
L
If a friend or acquaintance has the same watch, data can be transferred between those
watches (including time, date, alarm and dive alarm settings). In addition,
communication with a PC can also be performed using infrared communication.

charge the watch sufficiently before
diving to ensure safety.
* The above illustration provides a graphic representation of the amount of residual charge in the
watch and the changes in the charge level indicator.
27
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.
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
The EL light is desighed to enhance daylight viewing. At night an external light source
may be required to view the display.
