Enabling the CCR mode 

When the CCR mode is activated, the diluent tank appears in O

2

 setting.

See chapter: 

CCR

 to learn how to enable this mode.

The dive start setpoint (SP1) has a selectable range from 0.2 up to 0.95bar ppO

2

. The 

bottom setpoint (SP2) has a range from 1.0 up to 1.6bar ppO

2

 and this is switched normally 

active on the way to the bottom or when the bottom depth is reached. 
The SP switch depth is suggested by the dive computer the same way the gas switches are 
suggested in open circuit mode (predictive gas switching). 
The switch points are determined by the equivalent oxygen contents in open circuit mode. 
So, when the switch point is reached on the way down when the equivalent content of the 
gas at that depth reaches the diluent O

2

 level. 

For example, with a SP1 of 0.5bar of the air diluent the depth would be approximately 
13.8m/45.3ft in salt water.

3 .5  Warnings and alarms

The G2 can alert you to potentially 
dangerous situations via warnings and 
alarms. You can modify the warning and 
alarm settings in the menus or via a PC 
interface.

3 .5 .1 

Warning settings

Warnings represent situations that require 
diver’s attention; however, ignoring 
them does not necessarily represent an 
immediate risk. It is up to you to decide 
which ones you would like to be active. 
Warnings are shown in the pop-up window 
at the top of the display where button 
descriptions are normally viewed. The 
warning color is YELLOW and the related 
data window is highlighted at the same 
time.
Generally, warnings can be set to AUDIBLE, 
VISUAL, BOTH (audible and visual) or OFF.

The available warnings are:

3 .5 .2

Maximum depth will trigger a warning. See 
chapter: 

Maximum dive depth warning 

to learn how to set the warning depth.
