The receiver and transmitters each use mathematical formulas
called algorithms to change their codes each time the transmitter
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 transmitter "in sync" with the
control unit even if you use the remote control out of range of
the vehicle. However, if the transmitter has been pressed many
times out of range of the vehicle, or if the battery has been
removed, it may get out of sync with the control unit and fail to
operate the system. To re-sync the remote control simply press
of the transmitter several times within range of the vehicle.
The alarm will automatically re-sync and respond to the trans-
mitters normally.
note: Your system stores the last two triggered zones in
memory. If your system has been triggered but the LED
has been reset by turning on the ignition, your dealer can
still recall the last two zones that were triggered. Contact
your dealer for details.
