Driver Controls
The 2nd or 3rd press from step 3 will activate the door. The HomeLink
Universal Transceiver has now been trained to the receiver. The
remaining two buttons may now be programmed if this has not
previously been done.
Erasing HomeLink buttons
Individual buttons cannot be erased,
however, to erase the three
programmed buttons:
1. Hold down the two outside
buttons until the red light begins to
flash after 20 seconds.
2. Release both buttons.
Reprogramming a single HomeLink button
To program a device to HomeLink using a HomeLink button previously
trained, follow these steps:
1. Press and hold the desired HomeLink button. Do NOT release until
step 4 has been completed.
2. When the indicator light begins to flash slowly (after 20 seconds),
position the hand-held transmitter 5–14 cm (2 to 5 inches) away from
the HomeLink surface.
3. Press and hold the hand-held transmitter button.
4. The HomeLink indicator light will flash, first slowly and then rapidly.
When the indicator light begins to flash rapidly, release both buttons.
The previous device has now been erased and the new device can be
activated by pushing the HomeLink button that has just been
programmed.
Canadian Programming
During programming, your hand-held transmitter may automatically stop
transmitting after two seconds which may not be long enough to
program the HomeLink Universal Transceiver.
