The depth alarm is set to 40 m [131 ft] at the factory,

If set to the NITROX Mode, the correct oxygen per-
centage of the gas in your cylinder must always be
entered into the computer to ensure correct nitrogen
and oxygen calculations. In this mode also the oxygen
partial pressure limit can be set. The dive computer
calculates the equivalent allowed maximum depth
based on the set parameters.
To enter the Nitrox/Oxygen Setting Mode select
MODE- 3 SET- 1 SET DIVE- 4 NITROX (Fig.
