Homelink®
Universal remote
control
General information
Applies to vehicles: with Horne Link® universal remote
control
The Homelink universal remote control can
be programmed with hand -held transmitters
from existing equipment.
Using the Homelink universal remote control,
you can operate equipment such as garage
doors, property gates and house lights from inside your vehicle.
Using the Homelink universal remote control,
you can replace up to three separate hand ­
held transmitters for equipment on your
property with just one universal remote con­
trol. Most of these transmitters a re used to
operate ga rage doo rs and property gates. The
individua l transmitters are programmed at
the front bumper. That is where the control
module is located.
The transmitters must be programmed first in
order to operate systems using the Homelink universal remote control.
A WARNING
-
- Never use the Homelink® transmitter
with any garage door opener that does have not the safety stop and reverse fea­
ture as required by federal safety stand­ ards . Th is includes any garage door open­
er model manufactured before April 1, 1982.
- A garage door opener which cannot de­
tect an object, signaling the door to stop
and reverse does not meet current feder­
al safety standards. Using a garage door
opener without these features increases
risk of serious injury or death.
- For safety reasons never release the
parking brake or start the engine while
anyone is standing in front of the vehicle .
- A garage door or an estate gate may
sometimes be set in motion when the
Homelink ® 121
Homelink ® remote control is being pro­
grammed.
If the device is repeatedly ac­
tivated, this can overstrain motor and
damage its electrical components - an
overheated motor is a fire hazard!
- To avoid possible injuries or property
damage, please always make absolutely
certain that no persons or objects are lo­
cated in the range of motion of any
equ ipment being operated.
