Universal radio frequency remote
control
Applies to vehicles: with Homelink® universal radio frequency remote cont ro l
How it works
The HomeLink® universal remote control can be
programmed with the hand held transmitters of the equip ­
ment you want to activate from inside your car.
The Homelink® system is capable of operating up to three different
remote contro lled devices from inside your vehicle using the
Homelink ® universa l radio frequency remote control.
The system lear ns t he rad io frequency codes of handheld transmit ­
ters used to operate garage doors, estate gates, home or outdoor
l ighting systems, and other devices 1
l.
The original handhe ld transmitters allocated to the remote
control led devices maintain their ab ility to activate these devices
and can be sti ll be used .
The Homelink® system has a nonvolati le memory, so that all
program ming will be retained after the vehicle battery has
completely discharged or been disconnected .
Before y ou can use the Homelink® universa l remote cont rol to
operate radio -frequency remote controlled devices, you wi ll first
need to program the Ho melink® transmitter.
ll Fo r the sake of readabil ity, a ga rage door opene r is always referred to in this
descr iption.
