Always check the areas surrounding
garage doors and gates for people or
obstructions before programming or
during operation of the HomeLink system:
Programming or operating the HomeLink
system without verifying the safety of areas
surrounding garage doors and gates is
dangerous and could result in an
unexpected accident and serious injury if
someone were to be hit.
NOTE
The programming will not be erased even
if the battery is disconnected.
▼Pre-programming
the HomeLink
System
NOTE
It is recommended that a new battery be
placed in the hand-held transmitter of the
device being programmed to HomeLink
for quicker training and accurate
transmission of the radio-frequency signal.
Verify that there is a remote control
transmitter available for the device you
would like to program.
