CITIZEN MG0000 - Manual (Page 47)

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.
2. Depth Measurement
This watch measures depth every second, and continuously displays the current depth in 0.1 m
(1 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.
3. 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
4. Water Temperature Measurement
The watch starts to measure water temperature beginning 1 minute after the depth exceeds 1.0 m,
and measures at 1 minute intervals during the course of diving. The most recently measured
water temperature is displayed in 1°C (1°F) units during the time button (A) is pressed during the
scuba diving display. (The water temperature measured in 0.1°C (0.18°F) units is displayed after
rounding to the nearest 1°C (1°F) unit.)
• Measuring range: -9.4°C to +40.0°C (15°F to 104°F)
5. No. of Dives Per Day and Recording Log Data
A maximum of 15 sets of log data can be recorded in a single 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.
When the number of dives in one day is such that the number of skin dives is 15 or more and
the number of scuba dives is 14 or less, although the watch displays "FILE" when the dive is
started based on the judgment of the watch being used for skin diving, it judges that the watch is
being used for scuba diving 3 minutes later at which time "FILE" disappears from the display
and the dive is recorded as log data.
