3. Using both hands, press the hand-held transmitter button and the desired button on the HomeLink Transmitter. Continue to press both buttons through Step 4. 4. Hold down both buttons until you see the indicator light on the HomeLink Transmitter flash slowly and then rapidly. The rapid flashing indicates that the HomeLink Transmitter has been programmed. Release both buttons once the indicator light starts to flash rapidly. If you have trouble programming the HomeLink Transmitter, make sure that you have followed the directions exactly as described. The HomeLink Transmitter 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 "Rolling Code Programming" later in this section or contact the HomeLink Transmitter manufacturer at 1-800-355-3515. Be sure to keep the original hand-held transmitter in case you need to erase and reprogram the HomeLink Transmitter. Canadian Owners: During programming, the hand-held transmitter may automatically stop transmitting after one or two seconds. In this case, you should press and re-press the button on the hand-held transmitter every two seconds without ever releasing the button on the HomeLink Transmitter. Release both buttons when the indicator light on the HomeLink Transmitter begins to flash rapidly. 2-91
