1. Remove the sensor from the metal
valve stem.
2. Using a #00 Phillip’s screwdriver,
remove the two screws from the
battery cover on the side of the
sensor. The “+” side of the battery
can now be seen.
3. Remove the battery and check
that the metal contact points in the
sensor are not corroded. To clean
the contact points, use a pencil
easer and lightly rub the two metal
battery contacts in the sensor.
4. Replace with a new CR1632 battery.
Be sure the “+” (positive) side is facing
out.
Note:
It is recommended that you check
the voltage of the new battery
before installation. It should read
3.0 volts or greater when new.
5. Replace the “O” ring that surrounds
the battery compartment.
Additional “O” rings are provided in
your kit or can be purchased from
TST by calling 770-889-9102.
6. After the new battery and “O” ring
installation replace the battery
compartment cover and snugly
tighten the two screws. Do not Over
Tighten.
7. Screw the sensor on to the correct
tire position.
Note:
Changing the battery in the sensor
does NOT effect the sensor
programming in the display. You will
not have to reprogram the sensor
into the display.
