To program a garage door opener, park
outside directly in line with and facing the
garage door opener receiver. Clear all people
and objects near the garage door.
Make sure the hand-held transmitter has a
new battery for quick and accurate
transmission of the radio-frequency signal.
Programming the Universal Remote
System
Programming involves time-sensitive actions
and may time out, requiring the procedure
to be repeated. Read these instructions
completely before programming the
Universal Remote system. It may help to
have another person assist with the
programming process.
1. Hold the end of the hand-held
transmitter about 3 to 8 cm (1 to 3 in)
away from the Universal Remote system
buttons with the indicator light in view.
The hand-held transmitter was supplied
by the manufacturer of the garage door
opener receiver.
2. Press and release one of the three
Universal Remote system buttons to be
programmed. Press and hold the
hand-held transmitter button. Do not
release the hand-held transmitter button
until the indicator light changes from a
slow to a rapid flash or continuous light.
Then release the hand-held transmitter
button.
Some garage door openers may require
substitution of Step 2 with the procedure
under Radio Signals for Some Gate
Operators later in this section.
3. Press and hold the newly programmed
Universal Remote system button for
five seconds while watching the indicator
light and garage door activation.
If the indicator light stays on
continuously or the garage door
moves when the button is pressed,
then programming is complete. There
is no need to complete Steps 4 6.
If the indicator light does not come
on or the garage door does not
move, a second button press may be
required. For a second time, press
Instruments and Controls
and hold the newly programmed
button for five seconds. If the
indicator light stays on continuously
or the garage door moves when the
button is pressed, then programming
is complete. There is no need to
complete Steps 4 6.
If the garage door does not move,
continue with programming
Steps 4 6.

Learn or Smart button inside garage on
the garage door opener receiver. The
name and color of the button may vary
by manufacturer.
