• In Nitrox diving, coming close to or exceeding the maximum
water depth or dive time for the set FO
2
% increases the
oxygen partial pressure value and bodily oxygen quantity.
The effects on the human body due to oxygen become larger
and become very dangerous so be sure to avoid this.
Warning!
Multiple Gas Settings Diving (Accelerated Decompression)
The computer can record up to up to four tanks with different
FO
2
% and switch during diving (accelerated decompression). *
It is necessary to set the FO
2
% for GAS2-GAS4 for accelerated
decompression. If Nitrox is set, the FO
2
% flashes at the bottom left
of the screen in Time mode and Surface Mode. And, regardless of
whether or not multiple gases are set, FO
2
% is displayed for about
10 seconds when you start diving.
How to switch the gas
GAS1 is always selected at the start of the dive. Press and hold
A
for about 2 seconds and the currently used gas No. (first is GAS1)
and FO
2
% flash, and the current water depth is displayed.

When multiple gases are set, you can switch the gas on this
screen under water.
You can change the gas No. with
P
(gas No. UP) or the
L
(gas No.
DOWN), but if you are at a depth deeper than the allowable dive
water depth (oxygen partial pressures greater than 1.6 bar) you
cannot change the gas No. even if you press the buttons.
