Operating the HomeLinkR Transmitter Press and release the appropriate button on the HomeLink Transmitter. The indicator light comes on while the signal is being transmitted. If the hand-held transmitter appears to program the HomeLink Transmitter but does not open your garage door, and if the garage door opener was manufactured after 1996, the garage door opener may have a "rolling code" system. A rolling code system changes the code of the garage door opener every time you open or close the garage door. 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. "Rolling Code" Programming (If Equipped) If you have not previously programmed the hand-held transmitter to the HomeLink Transmitter, see "Programming the HomeLinkR 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. 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. 2-64
