LCD Transmitter Battery Replacement
Your Pager Remote Transmitter uses a 1.5 volt AAA alkaline battery, which will require replacement in time.
Depending on the amount of use, the battery may last up to 3 months before it needs replacement. When
the battery needs replacing, the system’s operating range will decrease, the LCD display will show only one
of three bars in the battery icon, or the display and sounds may suddenly stop and start as the battery
voltage drops below minimum.
In order to change the battery, first slide the battery door locking pin to the side. Carefully slide the battery
cover downward until it is free. While replacing the battery make sure that the positive and negative
terminals are positioned correctly, then carefully reassemble the transmitter case.

Battery Replacement
Your Remote Transmitter uses battery type 2016 for G777,G27 and 23A for A777,A20 which will
require replacement in time. Depending on the amount of use, the battery may last up to 24
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

Remote Arming
The system monitors 4 independent areas (zones) while armed: doors, hood/trunk, shock sensor
and optional sensor input.
To Arm the System:
1. Turn off the ignition.
2. Press Button 1.
· The siren will chirp once.*
· The doors will lock.
· The parking lights will flash once.
· The LED will turn on, to indicate the starter defeat is activated.
3. 5 seconds after Arming:
· The LED will start blinking to indicate that the doors and hood/trunk inputs are being
monitored.
* During Arming, if the system detects a bad sensor or an open zone, the system will chirp 4 additional times
and ignore that input, but keep all other areas protected.
Once Armed, the alarm will trigger when any of the following occurs:
·The doors are opened.
·The hood or trunk is opened.
·The shock sensor detects an impact to the vehicle.
·The optional sensor is disturbed.
When the alarm triggers, the siren will sound, the horn will honk, and the parking lights will
flash. If the system is triggered by the doors, or hood/trunk, the system will alarm for 45
seconds. If triggered by the shock sensor or optional sensor input, the system will alarm for
30 seconds.
In the event the alarm is triggered and remains triggered continuously by the same sensor
or input during a single arming cycle, that sensor or input will be automatically bypassed
until the next time the system is armed.
If the Shock Sensor detects a light impact to the vehicle, or the Optional Sensor’s warn-
away zone is disturbed, the siren will chirp 5 times as a warning indication.
Remote Disarming
To Disarm the System:
Press Button 2
· The siren will chirp twice.*
· The doors will unlock.
· The parking lights will flash twice and remain on for 30sec..
· The dome light will turn on.**
· The LED will turn off.
* During Disarming, if the system was triggered while away from the vehicle, the siren will chirp 3 times, the parking lights
will flash 3 times, and the LED will flash to indicate triggered zone. See Tamper Alert for zone listing.
** If the optional Dome Light Activation Feature is installed.
System Operation

A777, A20, G777, G27 Page 5
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
Silent Arming/Disarming
The system can be programmed to operate without Arm and Disarm chirp indications. When
programmed for full-time silent operation, the siren will sound only when the system is triggered.
The system is also capable of temporary silent operation if desired. Pressing the Shift button
before Arming or Disarming the system will bypass the chirp confirmations and allow one-time
silent operation.
Note: The open zone warning chirps will not be bypassed when the system is Armed or Disarmed silently.
Passive Arming
When programmed for the optional Passive Arming feature, the system arms itself automatically,
each time the ignition is turned off and all of the doors, hood, and trunk are closed.
To start the Passive Arming Process:
1. Turn off the ignition.
2. Open the door and exit the vehicle.
· Once all doors are closed and the dome light is off, the LED will begin flashing rapidly.
Parking Lights will flash twice three seconds after passive arming cycle began.
3. After 30 seconds,
· The siren will chirp.
· The parking lights will flash.
· The doors will lock.*
· The status LED will begin flashing.
4. The system is now armed.
* If the Passive Locking feature is selected.
