The computer can store up to 3 different Nitrox settings and can be switched
from 1 mix to another mid dive, providing that the PO2 for the gas is under 1.6 at
the depth when the switch is made and the oxygen % has been set before a dive
began.

[ DIVE mode - Deep stop ]
This dive computer has a DEEP STOP function. It is shown only under the
decompression mode and may require the diver to stay deeper than 21 meter.
One-minute stop(s) will be prescribed (much like a safety-stop) but in a deeper
area.
The stop before reaching the deepest decompression depth is calculated based on
a higher safety level of the algorithm. Please note that the total dive time will be
increase by the deep-stops.
The ascent rate under this function is 10m (33ft) per minute.
