Alarm and error messages
Description
Gas PPO2 unsafe
The gas will display in flashing red when its PPO2 is outside of a safe
breathing range (i.e. below the min PPO2 or above the max PPO2 set-
ting). In closed circuit (CC) mode, this warning refers to the diluent only.
The breathing loop PPO2 may be in a safe range, but if the diluent is
unsafe to breathe directly then the gas will be red. Note that other warn-
ings exist to warn when the breathing loop is outside of a safe range.

same dive, the PPO2 should once again be too high then it is not neces-
sary to confirm this again (see second image). The PPO2 values and
