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