<Regarding diving at high altitudes or in fresh water>
x
If you intend to use this watch for diving in a high place or in fresh
water, be sure to have a special education in safe diving beforehand.
x
Don't use the depth meter function of this watch in a high place 4,000-m
(13,120-ft) or more above sea level, because the watch gives incorrect
measurement of depth in such a place.
x
This watch indicates a depth based on the specific gravity (1.025) of
seawater. Therefore, if the watch is used in fresh water, the real depth is
2.5% less than the indication of the watch. Example: 20 m (65 ft)
(indicated depth) x 1.025 = 20.5 m (67 ft) (real depth)
When the watch is shifted to the dive mode, the pressure sensor
regards the ambient pressures as that on the sea level (0m/0ft in
depth or altitude) If the watch is shifted to the dive mode in a high
place, it regards the pressure on the surface of the water as that on
seal level (0m/0ft in depth/altitude). In short, the watch always
regards the surface of the water as that of sea level (0m/0ft) except
in a place 4,000m (13,120ft) or more above sea level. Therefore you
are advised
NOT TO
use the depth meter function of this watch at high
altitudes for the reason that the watch will give inaccurate
measurement in depth.
