The watch measures the water temperature
every minute in 0.1° C (1° F) increments from
-5.0° C up to +40.0° C (23° F up to 104° F). If
the measurement is outside the range, “Lo”
or “Hi” is displayed.
The water temperature at the maximum
depth is recorded in the dive log function.

Residual nitrogen at the end of a dive is
recorded in the dive function and indicated
graphically by the number of bars.
Residual oxygen at the end of a dive is
recorded in the dive function and indicated
graphically by the number of bars.
The depth at which the diver should make a
decompression stop. It is calculated on the
basis of the diving data collected during the
dive, and selected from 15, 12, 9, 6 and 3 m
(50, 40, 30, 20 and 10 ft). If the diver ascends
to a depth shallower than the indicated depth,
a decompression stop violation warning is
given.

De-
compression
stop depth
The time period during which the diver
should stay at the decompression stop depth.
It is calculated on the basis of the diving data
collected during the dive, and is counted
down while the decompression stop is being
made.
De-
compression
stop time
The minimum time required to stay
underwater before surfacing, including the
decompression stop.

PO2 is calculated on the basis of the depth
and the FO
2 setting (percentage of oxygen in
gas mixture). When PO
2 exceeds 1.5, a
warning is given.

The amount of excess oxygen in the diver’s
body is indicated graphically in 9 levels by
the number of bars shown on the display.
In nitrox diving, the diver is exposed to
higher levels of oxygen. If all the indicator
bars light up, ascend to a shallower depth,
as you are in danger of suffering from oxygen
toxicity.
