3. When the HomeLink indicator light begins to blink slowly (this may take up to 30 seconds), hold the hand-held transmitter about 1 to 3 inches (3 to 8 cm) away from HomeLink and then press and hold the transmit button on the hand-held transmitter. Continue to hold both buttons until the indicator light on HomeLink begins to flash rapidly (this may take up to 90 seconds). If you have trouble programming HomeLink, make sure that you have followed the directions exactly as described and that the battery in the hand-held transmitter is not weak. If you still cannot program it, move the hand-held transmitter to the left or right or forward or backward or flip it upside down. HomeLink may not work with older garage door openers that do not meet current Federal Consumer Safety Standards. If you cannot program the transmitter after repeated attempts, refer to "Training a Garage Door Opener with Rolling Codes" later in this section or contact the manufacturer of HomeLink at 1-800-355-3515, or on the internet at www.homelink.com. Be sure to keep the original hand-held transmitter in case you need to erase and reprogram HomeLink. Operating the HomeLink Transmitter Press and hold the appropriate button on HomeLink for at least half of a second. The indicator light will come on while the signal is being transmitted. Training a Garage Door Opener with a "Rolling Code" Feature (If Equipped) If you have not previously programmed the hand-held transmitter to HomeLink, 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 HomeLink. 1. Find the "Learn" or "Smart" button on the garage door opener motor head unit. The exact location and color will vary by garage door opener brand. If you have difficulty finding the "Learn" or "Smart" button, refer to your garage door opener owner's manual or contact the manufacturer of HomeLink at 1-800-355-3515, or on the internet at www.homelink.com. Because of the steps involved, it may be helpful to have another person assist in programming the transmitter. 2-76
