Code Hopping; Owner Recognition - Avital 5103 Owner's Manual

Code hopping

The receiver and transmitters use a math e mat i cal formula called an algorithm to
change their code each time the transmitter is used. This tech nol o gy has been
de vel oped to increase the security of the unit. The control unit knows what the
next codes should be. This helps to keep the trans mit ter "in sync" with the control
unit even if you use the remote control out of range of the vehicle. How ev er, if
the remote has been pressed many times out of range of the vehicle, or the bat-
tery has been removed, it may fall out of sync with the control unit and fail to
operate the system. To re-sync the remote press several times within range of
the vehicle. The alarm will automatically re-sync and respond to the trans mit ters
normally.

Owner recognition

Owner Recognition is a feature avail able only from Directed. Using a Directed
Bitwriter , hand-held programming tool, your dealer can program many of the
®
system settings. The programmer makes it possible to program different settings
for each trans mit ter that is used with the system. Then, when ev er a specific
transmitter is used, the system will recall the settings assigned to that transmitter.
Owner Rec og ni tion 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
vehicle, one for each user.
Important: Owner Recognition cannot be programmed without a Bitwriter® and
the necessary soft ware. Check with your dealer for more information.
