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.
a
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 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.
• Visually inspect the battery to ensure no damage has
occurred.
• When replacing the rear shell, ensure the charging pins
(bottom of inside rear shell) are aligned with the
corresponding holes on the PCB.
• Press the front and rear shells together firmly to ensure a
proper seal. Ensure the front and rear shell have a
uniform, tight 1/16 in. (1 mm) seal on all sides of the
detector.
• When replacing the screws, they must be seated properly
to prevent cross threading. Turn the screw counter-
clockwise until a click is heard and then begin tightening
the screw clockwise.
• New sensor(s) should be calibrated. Activate the detector
and calibrate the sensor(s). Refer to Calibration.
Note
Ensure the rib on the interior rear shell
inserts
between the battery and the PCB
. Refer to the
following illustrations.
