Setting PO2 Thresholds

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

  1. Hold MENU.
  2. Select Dive Setup > PO2.
  3. Select an option:
    • 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.

  4. Enter a value.

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