Code hopping

The receiver and transmitters use a mathematical formula called

an algorithm to change their code 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 remote 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 remote simply press

several times within

range of the vehicle. The alarm will automatically re-sync and

respond to the transmitters normally.

High frequency

Your system transmits and receives at 434 MHz. This provides a

cleaner spectrum with less interference and a more stable signal.

Enjoy a phenomenal increase in range, even in areas with high

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.
