KeyFob Power Supply
The KeyFob operates on a 3V Manganese Dioxide Lithium Coin Battery (
CR2032
).
Minimum operating voltage is approximately 2.6V, if the voltage drops below this level
the transmitter will cease operation, and the battery will need to be replaced. Please
replace battery with the aforementioned part number.
With the transmitter buttons facing down, use a thin coin to pry the two halves of the
transmitter apart. Use care to ensure that the rubber gasket is not damaged during
removal.
Remove and replace the batteries. Avoid touching the new batteries with your fingers.
Skin oils may cause battery deterioration.
Do not touch the printed circuit board or the battery terminals that are on the back
housing.
To reassemble the transmitter case, snap two halves together. Make sure there is and even
‘gap’ between the two halves.
