you live) asyou follow theprogramming
steps.

X Press button 0084again fortwo seconds.
X Repeat thissequence onbutton 0084of
remote control0083 until indicator lamp0043
lights upgreen.
When indicator lamp0043lights upgreen:
programming isfinished.
When indicator lamp0043flashes green:pro-
gramming wassuccessful. Thenext step is
to synchron izethe rolling code.
X Release button0084ofremote control0083 of

If indicator lamp0043lights upred: repeat the

so, vary thedistance between remotecon-

The required distance between remotecon-

Problems whenprogramming
If you areexperienc ingproblems programming
the integr atedgarage dooropener onthe rear-
view mirror, takenoteof the following instruc-
tions:
R Check thetrans mitterfrequency usedby
garage doordrive remote control0083 and
whether itis supported. Thetrans mitterfre- quency
canusuall ybe found onthe back of
remote control0083 for the garage doordrive.
The integr atedgarage dooropener iscom-
patible withdevices thathave units which
operate inthe frequency rangeof280 to
433 MHz.
R Replace thebatteries ingarage doorremote
cont rol0083. This increases thelikelihood that
garage doorremote control0083 will trans mit
a stron gand precise signaltothe integr ated
garage dooropener.
R When programming, holdremote control0083
at varying distances andangles frombut-
ton s0044 to0085 which youareprogramming.
Try various anglesatadistance between
2and 8inches (5to20cm) oratthe same
angle butatvarying distances .
R Ifanother remotecontrol0083 isavailab lefor
the same garage doordrive, repeat the
same programming stepswiththisremote
cont rol0083. Before performin gthese steps,
make surethatnew batteries havebeen
installed ingarage doordrive remote control

R Note thatsome remote controlsonly trans -
