Configure and preview the
Center row in this menu�

All three center row positions
are user configurable in OC Tec
mode� Only the left and right
positions are configurable in
CC/BO mode as the middle
position is reserved for PPO2
Setpoint�

For a complete list of configuration options, see the

The Perdix 2 has a mini display function that allows it
to show 3 pieces of information in each of the left and
right custom slots at the expense of font size�

Selecting one of the two mini display items in the
Center row setup menu will bring you to the Mini
Display Setup Menu for that mini display�

Note that not all mini-displays will show units due to
space constraints�

11.5. OC Gases (BO Gases)

This menu allows the user to
edit the open circuit gas list�
The options contained here
are the same as those in the
“Define Gases” subsection of
the “Dive Setup” section on
page 55� This menu page
conveniently displays all five
gases simultaneously�

Each gas can be turned on or off and set to any
concentration of O2 and helium� The remaining
percentage is assumed to be nitrogen�

The active gas is shown with a leading ‘A’� All gases
that are turned off are drawn in magenta (purple)�

In CC/BO mode, this menu is titled “BO Gases”� Note
that the gas list is shared between OC Tec and Bailout
modes�

11.6. CC Gases

This menu allows the user to
edit the closed circuit diluent
gas list� The options contained
here are the same as those in
the OC Gas list setup menu�
