Setting PO2 Thresholds
You can configure the partial pressure of oxygen (PO2) thresholds, in bars, for decompression, warning, and critical alerts.

- Select Deco PO2 to set the threshold that you can reach before you should begin your ascent and switch to the decompression gas with the highest percentage of oxygen.
NOTE: The device does not switch gases for you automatically. You must select the gas.
- Select PO2 Warning to set the threshold for the highest oxygen concentration level that you are comfortable reaching.
- Select PO2 Critical to set the threshold for the maximum oxygen concentration level that you should reach.
- Select Deco PO2 to set the threshold that you can reach before you should begin your ascent and switch to the decompression gas with the highest percentage of oxygen.

If you reach a threshold value during a dive, the device displays an alert message.
