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
range of the vehicle. The alarm will automatically re-sync and
respond to the transceivers normally.

Owner Recognition is a revolutionary new feature available only
from Directed. Using a Directed Bitwriter, hand-held program-
ming tool, your dealer can program many of the system settings.
The programmer makes it possible to program different settings
for each transceiver that is used with the system. Then, whenev-
er a specific transceiver is used, the system will recall the settings
assigned to that transceiver. Owner Recognition lets up to four
users of the system have different settings that meet their specific
needs. It is almost like having four separate alarms in your
