To enter the Dive Parameter Setting Mode 
select MODE- 3 SET- 1 SET DIVE. The Dive 
Parameter Setting mode has two to four op-
tions depending on the dive computer mode. 
In Gauge mode there are two options, in Air 
mode three options and in Nitrox mode four 
options.

The current Altitude and Personal Adjustment 
modes are shown when diving and at the sur-
face. If the mode does not match the altitude 
or personal conditions (see section 3.8. “High 
Altitude Dives and Personal Adjustment”), it 
is imperative that you enter the correct selec-
tion before diving. Use the Altitude Adjustment 
to select the correct altitude mode. Use the 
Personal Adjustment to add an extra level of 
conservatism.

For certain divers and diving conditions you 
may want to set attenuated RGBM mode When 
this selection is made it is indicated with a con-
tinuously displayed Diver Attention Symbol. 
The options are full RGBM effects (RGB100), 
and attenuated RGBM (RGB50).

The deepstop setting allows the user to choose 
between traditional safety stops or deep stops. 
If deep stops are set to OFF, traditional safety 
stop calculation is used. If set to ON itera-
tive Deepstops will be prompted instead. The 
length of the individual deepstops can be set 
to 1 or 2 minutes.

To enter the Altitude Adjustment, Personal Ad-
justment and RGBM effect Setting mode, se-
lect MODE- 3 SET- 1 SET DIVE- 1 AdJ MODE.
