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 no-
decompression 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.
