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.
