Maintenance

Replacing the oxygen sensor

Note

Detectors that are configured for 1, 2, or 3 gases may

contain a dummy sensor in one of the four sensor

locations.

1. Gently remove the circular rigidified flex PCB atop the

sensor from the metal sensor posts. Take care not to

tear the flex cable.

2. Note the placement of the PCB to ensure it is

replaced correctly. Remove the two screws on the

PCB.

Caution

Ensure no damage occurs to the battery.

3. Lift the PCB straight up. The oxygen sensor will stay

in the front shell. Remove the sensor.

4. On roughly the same spot on the front shell, place the

new sensor. Lower the PCB over the oxygen sensor.

5. Ensure the purple plastic sensor post is inserted into

the clear plastic hole. Carefully replace the circular

rigidified flex PCB atop the metal sensor posts. Take

care not to tear the flex cable.

6. Press down to secure the circular rigidified flex PCB

atop the metal sensor posts.

7. To complete the detector, refer to Reassembling the

detector.

Reassembling the detector

• Verify the PCB is seated correctly and inserted exactly

as it was removed (sensors face the front shell).

Replace the two PCB screws.
