ting is achieved, the siren will emit two short chirps followed
by a long chirp. When the minimum setting (full trigger off)
is achieved, the siren will emit one short chirp followed by a
long chirp.
NOTE: If more than five seconds elapse without an adjustment, shock
sensor adjustment mode will be exited. Repeat steps 1 through 3 to make
additional adjustments. The siren will generate one long chirp followed
by two short chirps when the shock sensor adjustment mode has been
exited.
Code Hopping ™
The receiver and transmitters each use a mathematical formula
called an algorithm to change their code each time the transmit-
ter 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 synchronized with
the control unit even if you use the remote control out of range
of the vehicle. However, if the transmitter has been pressed many
times out of range of the vehicle, or the battery has been removed,
it may get out of sync with the control unit and fail to operate the
system. To resynchronize the remote control simply press on
the remote control several times within range of the vehicle. The
alarm will automatically resynchronize and respond to the trans-
mitters normally.
