If you live in Canada, or you are having difficulty
programming a gate operator by using the
"Programming HomeLink@" procedures (regardless of
where you live), replace Step 3 under "Programming
HomeLink@" with the following:
Continue to press and hold the HomeLink@ button while
you press and release every two seconds (cycle)
your hand-held transmitter until the frequency signal has
been successfully accepted by HomeLink@. The
indicator light will flash slowly at first and then rapidly.
Proceed with Step 4 under "Programming HomeLink@'
to complete.
Using HomeLinkO
Press and hold the appropriate HomeLink@ button for at
least half of a second. The indicator light will come
on while the signal is being transmitted.
Erasing HomeLink@ Buttons
To erase programming from the three buttons do the
following:
1. Press and hold down the two outside buttons until
the indicator light begins to flash, after 20 seconds.
2. Release both buttons. Do not hold for longer than
30 seconds.
HomeLink@ is now in the train (learning) mode and can
be programmed at any time beginning with Step 2
under "Programming HomeLinkO."
Individual buttons can not be erased, but they can be
reprogrammed. See "Reprogramming a Single
HomeLinkO Button" next.
Reprogramming a Single HomeLinkO
Button
To program a device to HomeLinkO using a HomeLink@
button previously trained, follow these steps:
1. Press and hold the desired HomeLink@ button. Do
not release the button.
2. The indicator light will begin to flash after
20 seconds. While still holding the HomeLink@
button, proceed with Step 2 under "Programming
HomeLink@."
Resetting Defaults
To reset HomeLink@ to default settings do the following:
1. Hold down the two outside buttons for about
20 seconds until the indicator light begins to flash.
2. Continue to hold both buttons until the HomeLinkO
indicator light turns off.
3. Release both buttons.
