Example If zone 3 was active or triggered, the LED will blink three times with a two-second pause. Then it will blink three times again, and repeat until the ignition is turned on. 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. 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 security 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. © 2005 directed electronics-all rights reserved 39

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.
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.
