Programming integrated remote
control
Step 1:
Switch on the ignition ( page 344).
Step 2:
If you have previously programmed a
signal transmitter button and wish to
retain its programming, proceed to
step 3.
If you are programming the integrated
remote control for the first time, press
and hold the two outer signal transmit-
ter buttons 2 and 4 and release
them only when indicator lamp 1 be-
gins to flash after approximately
20 seconds (do not hold the button for
longer than 30 seconds). This proce-
dure erases any previous settings for
all three channels and initializes the
memory.

If you later wish to program a second
and/or third hand-held transmitter to
the remaining two signal transmitter
buttons, do not repeat this step and be-
gin directly with step 3.
Step 3:
Hold the end of hand-held remote
control 5 of the device you wish to
train approximately 2 to 5 in
(5 to12 cm) away from the signal trans-
mitter button (2, 3 or 4) to be pro-
grammed, while keeping indicator
lamp 1 in view.
Step 4:
Using both hands, simultaneously
press hand-held remote control
button 6 and the desired signal trans-
mitter button (2, 3 or 4). Do not
release the buttons until step 5 is com-
pleted.
Indicator lamp 1 will flash, first slowly
and then rapidly.
i
Indicator lamp 1 flashes immediately the
first time the signal transmitter button is pro-
grammed. If this button has already been pro-
grammed, the indicator lamp will only start
flashing after 20 seconds.
Step 5:
After indicator lamp 1 changes from a
slow to a rapidly flashing light, release
the hand-held remote control button
and the signal transmitter button.
Step 6:
Press and hold the just-trained signal
transmitter button (2, 3 or 4) and
observe indicator lamp 1.
If indicator lamp 1 stays on
constantly, programming is complete
and your device should activate when
the respective signal transmitter
button (2, 3 or 4) is pressed and re-
leased.
