Garage Door Opener (GDO) - Programming - Universal

Turn the ignition OFF while programming the transmitter. Follow these steps to program up to three channels:
1. If you have previously programmed a transmitter, proceed to step 2. Otherwise, hold down the two outside buttons on the GDO transmitter until the light on the GDO transmitter begins to flash rapidly (approximately 20 seconds). Then release the buttons. This procedure initializes the memory and erases any previous settings for all three channels.
2. Decide which of the three channels you want to program.
3. Hold the end of the hand held transmitter against the front surface of the GDO (less than one inch) so you can still see the light.
4. Using both hands, press the hand-held transmitter button and the desired button on the GDO transmitter. Continue to hold both buttons through step 5.
5. Hold down both buttons until you see the light on the GDO transmitter flash slowly and then rapidly. The rapid flashing, which could take up to 90 seconds, indicates that the GDO transmitter has been programmed. Release both buttons once the light starts to flash rapidly.
