  2. Select Plan Dive > Calculate Gas.
  3. Press Middle-left button or Lower-left button, and select an option to calculate:

    • Select PO2.

    • Select O2%.

    • Select Depth.

  4. Press Middle-left button or Lower-left button to edit the first value.
  5. Press Upper-right button, then press Middle-left button or Lower-left button to edit the second value.

    As you edit the values, the device calculates an adjusted value for the highlighted option.
