TRANSMITTER BATTERY REPLACEMENT
You will notice a decrease in transmitter range as the battery condition
deteriorates. Transmitter battery replacement is recommended at least every 10
to 12 months, depending upon how frequently the transmitter is used.
The transmitter has a small yellow LED visible through the case. This LED can
be used to indicate battery condition. If the LED does not illuminate, then the
battery is discharged, and must be replaced.
To replace the transmitter battery,
1. Remove the small phillips head screws from the bottom cover of the
transmitter.
2. Carefully unsnap the top cover of the trans-
mitter from the bottom cover.
3. Remove the discharged battery, making
note of the location of the + and - contacts,
and replace with a new type GP 27A 12 volt
battery.
4. Replace the transmitter cover, taking care
not to damage the LED or switches on the
circuit board, and secure with the small
phillips head screw.
