does not move, a second
button press may be
required. For a second time,
press and hold the newly
programmed button for
five seconds. If the light stays
on or the garage door moves,
programming is complete.
If the indicator light blinks
rapidly for two seconds, then
changes to a solid light and
the garage door does not
move, continue with
programming Steps 4 6.
