Changes and modifications to this system by other than an authorized service facility could void authorization to use this equipment. Be sure that people and objects are clear of the garage door or gate operator you are programming. When programming a garage door, it is advised to park outside of the garage. It is recommended that a new battery be installed in your hand-held transmitter for quicker and more accurate transmission of the radio frequency. Programming the HomeLink Transmitter Do not use the HomeLink@ Transmitter with any garage door opener that does not have the "stopand reverse" feature. This includes any garage door openermodel manufactured before April 1, 1982. Your vehicle's engine should be turned off while programming the transmitter. Follow these steps to program up to three channels: 1. Press and hold down the two outside buttons, releasing only when the indicator light begins to flash, after 20 seconds. Do not hold down the buttons for longer than 30 seconds and do not repeat this step to program a second and/or third transmitter to the remaining two HomeLink@buttons. 2. Position the end of your hand-held transmitter about 1 to 3 inches (3 to 8 cm) away from the HomeLink@ buttons while keeping the indicator light in view. 3. Simultaneously press and hold both the desired button on HomeLink@ and the hand-held transmitter button. Do not release the buttons until Step 4 has been completed. Some entry gates and garage door openers may require you to substitute Step 3 with the procedure noted in "Gate Operator and Canadian Programming" later in this section. 2-45 Keep the original transmitter for use in other vehicles as well as for future HomeLink@ programming. It is also recommended that upon the sale of the vehicle, the programmed HomeLink@buttons should be erased for security purposes. Refer to "Erasing HomeLink@ Buttons" or, for assistance, contact HomeLink@ the on internet at: www.homelink.com or by calling 1-800-355-351 5.
