Battery Replacement
Your Remote Transmitter uses a 12 volt alkaline battery (type 23A), which will require
replacement in time. Depending on the amount of use, the battery may last up to six months
or more before it needs replacement.
When the battery needs replacing, the system’s operating range will decrease or the transmitter
LED may not be as bright.
In order to change the battery, first remove 2 screws from the back of the transmitter and
separate the top and bottom halves of the case.
While replacing the battery make sure that the positive and negative terminals are positioned
correctly, then carefully reassemble the transmitter case.
Tamper Alert
If the system was triggered while away, the LED will flash to indicate which zone triggered the
system after disarming and turning on the ignition. The LED indication will repeat 8 times.
LED Flashes:
1 flash = optional sensor
2 flashes = shock sensor
3 flashes = not used
4 flashes = door
5 flashes = trunk
10 flashes = main power interrupt or system was reset
example: flash-flash-pause-flash-flash-pause = shock sensor
