Code Hopping
The receiver and transmitter use mathematical formulas called
algorithms to change their codes each time the transmitter is
used. This Code Hopping technology has been developed to
increase the security of the unit. By following this set code
sequence, the receiver and transmitter stay synchronized, even if
the remote transmitter is used out of range of the vehicle. If,
however, the transmitter is pressed many times out of range of the
vehicle, or the battery is removed, the transmitter may get tem-
porarily out of sync and fail to operate the system. To
resynchronize the remote transmitter, simply press several
times within range of the vehicle. The system will automatically
resynchronize and the transmitter will respond normally.
Rapid Resume Logic
Your vehicle security system stores its current operational state in
non-volatile memory, so that if power is lost and then recon-
nected, the system can recall the stored state from memory. For
example, if the system is in Valet Mode when the battery is dis-
connected, it will still be in Valet Mode when the battery is
reconnected. This applies to all system features, including arming,
disarming, and Valet Mode.
