its socket.

WARNING:
Any new sensor fitted to a device will take time to settle to a stable reading. For
this reason, once the sensor has been fitted, the device should be left un-powered for at least
2 hours before attempting to power-up and calibrate.
Once the sensor has been allowed to settle, replace the batteries and fit the battery cover. Power the
device and allow the sensor(s) to warm up. The new oxygen sensor will require calibration and may be
showing a fault due to an over-range reading (this is normal for a new sensor). To calibrate the oxygen
sensor, follow the instructions in the section ‘Oxygen fresh air calibration’.
