Special Consideration for Oxygen Sensor

Under the following situations, the oxygen sensor display reading may be suppressed for up to
30 minutes at device turn-ON as a sensor 'cook down' is performed.
This could occur if:
-
the oxygen sensor was just installed
-
the battery pack was allowed to be deep-discharged
-
the battery pack was removed from the device.
During this time, the oxygen sensor numeric position on the display indicates "PLEASE WAIT". While
this message displays, the device cannot respond to a:
-
Fresh Air Setup
-
Calibration
-
Bump Test procedure.
When the numeric oxygen reading appears, the FAS, calibration, or Bump Test procedures may be
performed.
