Replacing Battery
The coin cell battery (CR1632) used in the FOBO TIRE 2 sensors could last up to
one year based on normal operating condition. Similarly the AA battery used in
FOBO TIRE 2 In-Car unit could last up to two years based on normal operating
condition. Operating in extreme cold or hot temperatures may reduce battery
operating life for both the tire sensors and the In-Car unit.
To replace the battery of sensor unit, unscrew the top cover. Be careful not to damage
the rubber gasket as it may affect water resistance of the sensor unit. Ensure the
battery (CR1632) is inserted with the “+” sign facing up, away from the PCB.
To replace battery for the In-Car unit, slide out the battery cover. Ensure the battery
(AA) is inserted in the correct orientation. It is advisable to use good quality AA
batteries (recommended Lithium or Alkaline) for longer lasting performance of In-
Car unit.
Note:
It is recommended to remove sensor/in-car unit batteries if you are not going
to use it for long time.
