4. The indicator light will flash slowly and then rapidly after HomeLink successfully receives the frequency signal from the hand held transmitter. Release both buttons. 5. Press and hold the just-trained HomeLink button and observe the indicator light. If the indicator light stays on constantly, programming is complete and your device should activate when the HomeLink button is pressed and released. To program the remaining two HomeLink buttons, begin with Step two under "Programming HomeLink". Do not repeat Step 1 as this will erase all of the programmed channels. If the indicator light blinks rapidly for two seconds and then turns to a constant light, continue with Steps 6-8 following to complete the programming of a rolling code equipped device (most commonly a garage door opener). 6. At the garage door opener receiver (motor-head unit) in the garage, locate the "Learn" or "Smart" button. This can be usually found where the hanging antenna wire is attached to the motor-head unit. 7. Firmly press and release the "Learn" or "Smart" button. The name and color of the button may vary by manufacturer. You will have 30 seconds to start Step 8. 8. Return to the vehicle and firmly press, hold for two seconds, and release the programmed HomeLink button. Repeat the press/hold/release sequence a second time, and depending on the brand of the garage door opener (or other rolling code device), repeat this sequence a third time to complete the programming. HomeLink should now activate your rolling code equipped device. To program the remaining two HomeLink buttons, begin with Step 2 of "Programming HomeLink". Do not repeat Step 1. 2-73
