Breaking the decompression ceiling
When you ascend above the ceiling by more than 0.6 m (2 ft), the ceiling parameter turns red,
a red arrow pointing down appears, and an audio alarm is generated.
Explanation
Gas time is below your gas time alarm limit, or tank
pressure is below 35 bar (~510psi), in which case gas
time is zero.
Mandatory safety stop ceiling broken by more than 0.6
m (2 ft)
Tank pressure is below your tank pressure alarm limit.
There is a built in 50-bar alarm that cannot be changed.
In addition to it there is a configurable tank pressure
alarm, you can set to any value and your dive computer
also shows an alarm when that value and 50 bar
pressures are reached. The tank pressure number is
forced onto the display and turns yellow after the value
you set and red after 50 bar.
Explanation
Central nervous system toxicity level at 80% limit
Approximately 80% of recommended daily limit for OTU
reached
On multi-gas dive when ascending, it is safe to switch to
next available gas for optimum decompression profile
Approximately three hours of dive time left
Approximately two hours of battery time left; re-charging
required before next dive
Tank POD battery life low; battery change required
