Step 12:
Confirm the garage door operation by
pressing the programmed integrated
signal transmitter button (2, 3
or4).
Step 13:
To program the remaining two buttons,
repeat the steps above starting with
step 3.Gate operator/Canadian programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission
which may not be long enough for the inte-
grated signal transmitter to pick up the sig-
nal during programming. Similar to this
Canadian law, some U.S. gate operators
are designed to “time-out” in the same
manner. If you live in Canada or if you are having dif-
ficulties programming a gate operator (re-
gardless of where you live) by using the
programming procedures, replace step 4
with the following:
Step 4:
Continue to press and hold the inte-
grated signal transmitter button (2,
3 or4) while you press and re-press
(“cycle”) your hand-held remote con-
trol transmitter6 every two seconds
until the frequency signal has been
learned. Upon successful training, the
indicator lamp1 will flash slowly and
then rapidly after several seconds.
Proceed with programming step 5 and
step 6 to complete.

292 Controls in detailUseful featuresOperation of integrated remote control
Switch on ignition (
page 36).
Select and press the appropriate
integrated signal transmitter button
(2, 3 or4) to activate the remote
controlled device.
The integrated remote control trans-
mitter continues to send the signal as
long as the button is pressed – up to
20 seconds.Erasing the integrated remote control
memory
Switch on ignition (
page 36).
Simultaneously hold down the signal
transmitter buttons2 and 4, for
approximately 20 seconds, until the
indicator lamp1 flashes rapidly. Do
not hold for longer than 30 seconds.
The codes of all three channels are
erased.Reprogramming a single integrated
signal transmitter button
To program a device using a signal trans-
mitter button previously trained, follow
these steps:
Press and hold the desired signal
transmitter button (2, 3 or4).
Do not release the button.
The indicator lamp will begin to flash
after 20 seconds. Without releasing
the integrated signal transmitter
button, proceed with programming
starting with step 3.
iIf you sell your vehicle, erase the codes
of all three channels.
