TRANSMITTER
REPLACEMENT OF THE BATTERY
If the transmitter becomes unreliable, replace the battery.
As the battery power is consumed, the operation distance will be
shorter.
1) Put the edge of a coin or a flat blade screw driver in the slot (1)
of the transmitter and pry it open.
2) Replace the battery (lithium disc-type CR2032 or equivalent) so
its
terminal faces the ª+º mark of the transmitter.
CAUTION:
Use care not to allow grease or dirt to be attached on the
printed circuit board and the battery.
3) Close the transmitter firmly.
4) Make sure the door locks can be operated with the transmitter.
NOTE:

To prevent theft, be sure to break the transmitter before
discarding it.

Dispose of the used battery properly according to appli-
cable rules or regulations. Do not dispose of lithium bat-
teries with ordinary household trash.
