ALERT DISPLAY SCREENS
These sample screens correspond to the errors listed above.
Each of the alerts will display the message until dismissed. The
error is dismissed by pressing SELECT.
PPO2
This message will appear if the average PPO2 goes
above 1.6 for more than 30 seconds.
This message will appear if the average PPO2 goes
below 0.4 (.19 for OC or SC) for more than 30 seconds.
It is not unusual to get this error immediately after
submerging with a manual CCR and a hypoxic mix.
The first breath after submerging floods the loop
with low PPO2 gas. The situation is usually resolved
by increasing depth such that when the error is
noticed, the PPO2 is no longer low.
Battery
This message will appear when your internal battery
is low for 30 seconds. The battery needs to be
changed. The computer will also flash the battery
symbol red.
Ascent
This alarm is a notification that there has either been a
very fast ascent for a short period of time, or that there
has been an ascent of more than 66 fpm / 20 mpm
maintained for over a minute. This alarm may return
after being dismissed if the condition occurs again.
