Arming and disarming diagnostics (including Warn Away
responses) are reported by the transceiver on the LCD.
When a Bypass Notification is generated during arming the
transceiver LCD will flash until the alarm is reset by the
ignition.
To review zones that have been bypassed press
seconds after arming the system. The bypassed zones will
flash until the alarm is reset by the ignition.
When a Tamper Alert notification is generated upon
disarming, the triggered zones will flash continuously on the
transceiver LCD until reset by the ignition.
To review the zones that have been triggered press the
button. They flash five times, then turn off.

The receiver and transmitters use a mathematical formula called
an algorithm to change their code each time the transceiver is
used. This technology has been developed to increase the secu-
rity of the unit. The control unit knows what the next codes should
be. This helps to keep the transceiver "in sync" with the control
unit even if you use the transceiver out of range of the vehicle.
However, if the transceiver has been pressed many times out of
range of the vehicle, or the battery has been removed, it may fall
out of sync with the control unit and fail to operate the system.
To re-sync the transceiver simply press
