WHEN IT DETECTED SIGNALS THAT IS OUT OF PRE-SET CONDITIONS.

9 Replacing Battery
The coin cell battery (CR2032) used in FOBO Tire sensors could last up to two years on
normal operation. Similarly the AA battery used in FOBO Tire In-car unit could last up
to two years on normal operation. Operating in extreme cold temperatures may reduce
battery operating life for both sensors and In-car unit.
You will get an alert on the smart phone and in-car unit when the sensor or In-car unit
battery goes below indicated level. You will be alerted every time you start to drive your
car until the battery is replaced. It is advisable to change the battery once you get this
battery alert to ensure proper performance of FOBO Tire. Do not wait until the battery is
fully drained as it will cause FOBO Tire to stop working especially when you need it.
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
(CR2032) is inserted “+” side up facing 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.
WARNING: RE-USING OLD BATTERIES OR MIXING OLD AND NEW
BATTERIES IN IN-CAR UNIT MAY DAMAGE THE ELECTRONICS.
