If you have trouble programming the HomeLink
Transmitter, make sure that you have followed the
directions exactly as described and that the battery in the
-
hand held transmitter is not dead. If you still cannot
-
program it, turn the hand
and try again. The HomeLink Transmitter may not work
with older garage door openers that do not meet current
Federal Consumer Safety Standards. If you cannot
program the transmitter after repeated attempts, refer to
"Training a Garage Door Opener with Rolling Codes"
later in this section or contact the manufacturer of the

unit at 1 800 355 3515.
Be sure to keep the original hand
in case you need to erase and reprogram the
HomeLink Transmitter.
