Useful features Rolling code programming To train a garage door opener (or other rolling code devices) with the rolling code feature, follow these instructions after completing the "Programming" portion (steps 1 through 6) of this text. For your convenience and to complete the procedure faster, you might want to have someone assist you. X Step 8: Locate the "training" button on the garage door opener motor head unit. Gate operator/Canadian programming Canadian radio-frequency laws require transmitter signals to "time-out" (or quit) after several seconds of transmission which may not be long enough for the integrated signal transmitter to pick up the signal during programming. Similar to this Canadian law, some U.S. gate operators are designed to "time-out" in the same manner. If you live in Canada or if you are having difficulties programming a gate operator (regardless of where you live) by using the programming procedures, replace step 4 with the following: X Step 4: Press and hold the signal transmitter button (;, = or ?). Do not release this button until it has been successfully trained. X While still holding down the signal transmitter button (;, = or ?), "cycle" your hand-held remote control button B as follows: Press and hold button B for 2 seconds, then release it for 2 seconds, and again press and hold it for 2 seconds. Repeat this sequence on the hand-held remote control until the frequency signal has been learned. Upon successful training, indicator lamp : will flash slowly and then rapidly after several seconds. X Proceed with programming step 5 and step 6 to complete. 221 i Exact location and color of the button may vary by garage door opener brand. Depending on manufacturer, the "training" button may also be referred to as "learn" or "smart" button. If there is difficulty locating the transmitting button, refer to the garage door opener Operator's Manual. X Step 9: Press the "training" button on the garage door opener motor head unit. The "training light" is activated. You have 30 seconds to initiate the following two steps. X Step 10: Return to the vehicle and firmly press, hold for 2 seconds and release the programmed signal transmitter button (;, = or ?). X Step 11: Press, hold for 2 seconds and release same signal transmitter button a second time to complete the training process. i Some garage door openers (or other rolling code equipped devices) may require you to press, hold for 2 seconds and release the same signal transmitter button a third time to complete the training process. X Step 12: Confirm the garage door operation by pressing the programmed signal transmitter button (;, = or ?). X Step 13: To program the remaining two signal transmitter buttons, repeat the steps above starting with step 3. i Upon completion of programming the integrated remote control, make sure you retain the hand-held remote control that came with the garage door opener, gate operator or other device. You may need it for use in other vehicles, for future programming of an integrated remote control, or simply for continued use as a hand-held remote control to operate the respective device in other situations.
