To determine if you have this system, press the button on the HomeLink Transmitter that you have programmed already. If the indicator light on the HomeLink Transmitter flashes rapidly for two seconds and then turns solid, the garage door opener has a rolling code system. In a rolling code system, the garage door motor head unit must be trained to the HomeLink Transmitter. 1. Find the training button on the garage door opener motor head unit. The exact location and color of the button may vary by garage door opener brand. If you have difficulty finding the training button, refer to your garage door opener owner's manual. Because of the steps involved, it may be helpful to have another person available to assist in programming the transmitter. 2. Press the training button on the garage door opener motor head unit. Following this step, you have 30 seconds to start Step 3. 3. Return to the HomeLink Transmitter in your vehicle and firmly press and release the HomeLink Transmitter button you have already programmed for two to three seconds. Press and release the button again (you may need to do this step up to three times) to make sure that the HomeLink Transmitter has been trained to the garage door opener motor head unit. Check that the training was successful. "Rolling Code" Programming (If Equipped) If you have not previously programmed the hand-held transmitter to the HomeLink Transmitter, see "Programming the HomeLink Transmitter" listed previously. If you have completed this programming already, you now need to train the garage door opener motor head unit to recognize the HomeLink Transmitter. Refer to your garage door opener owner's manual for the proper transmitter training procedure for your garage door opener brand. 2-60
