Special Consideration For Oxygen Sensor; Measurement Mode (Normal Operation); Motionalert - MSA Altair 5X Mode D'emploi

3.2.3 Special Consideration for Oxygen Sensor

Under the following situations, the oxygen sensor display reading may
be suppressed for up to 30 minutes at instrument 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 instrument.
During this time, the oxygen sensor numeric position on the display
indicates "PLEASE WAIT". While this message displays, the instrument
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.
