J. PRECAUTIONS FOR DIVING MODE USE
Making accurate depth readings
1. Switch the watch to the Diving Mode shortly before diving
In case the watch, though being used on land, is out in the diving mode because the water sensor sen-
ses moisture such as sweat, make the watch released from the diving mode by wiping off the moistu-
re, then switch it to the diving mode again.
2. Avoid too rapid descent and ascent when diving. In case the diver rapidly ascends at a rate of 1.5
meters (5ft) or more per 10 seconds, the ascending speed alarm beeps for more than 10 seconds and
the display of depth readings becomes flashing, not allowing proper measurement. When the diver
rapidly descends or ascends at a rate of 4 meters (15ft) or more per second, the display indicates ER
(Error).
High altitude & Freshwater diving
When the Diving Mode is activated, the depth is calibrated at 0 meter.
However, an accurate measurement is not possible at altitudes over 4,000 meters (13,124 ft).
Do not use this watch when diving in such places. Further, this watch displays changes in depth based
on a standard of seawater (density 1,025).
Depths indicated in fresh water will actually be about 2.5% over indicated.
Be sure to complete appropriate safety training before diving in fresh water or at high altitudes.
(Example) 20 meters in fresh water (indicated depth) x 1.025 = 20.5 meters (actual depth).
