Returning to Normal Operation

1. Wait 1 to 2 minutes to allow the oxygen reading at the controller to return to normal, then return the

controller to normal operation.

NOTE:

If you do not allow the oxygen reading to return to normal, then unwanted alarms may occur.

2. Verify that the controller display reading stabilizes at 20.9%.

3. Store the components of the calibration kit in a safe and convenient place.
