Mix number, O2%, He% and PO2 for the mixes are shown when scrolling. If the set PO2 limit is exceeded , it will be shown with the PO2 value blinking. The dive computer does not allow you to change to a gas whose set PO2 is exceeded. In such a case, the mix is shown but cannot be selected. If the PO2 is less than 0.18 bar, the dive computer gives an alarm.

If no button is pressed in 15 seconds, the dive computer will go back to the dive display without changing the gas mix. Upon ascent, the computer prompts you to change gas when the PO2 level you have set for the next mix allows a gas change. The prompt is an audible 3 beeps and the current O2 or O2: He mix starts to blink.
