Press, hold for two seconds and re-
lease same button a second time to
complete the training process.
Some garage door openers (or other rolling
code equipped devices) may require you to
perform this procedure a third time to
complete the training.
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,

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.
