Gate Operator and Canadian Programming Canadian radio-frequency laws require transmitter signals to time out or quit after several seconds of transmission. This may not be long enough for Universal Home Remote to pick up the signal during programming. Similarly, some U.S. gate operators are manufactured to time out in the same manner. If you live in Canada, or you are having difficulty programming a gate operator or garage door opener by using the "Programming Universal Home Remote" procedures, regardless of where you live, replace Step 3 under "Programming Universal Home Remote" with the following: Continue to press and hold the Universal Home Remote button while you press and release every two seconds (cycle) the hand-held transmitter button until the frequency signal has been successfully accepted by the Universal Home Remote. The Universal Home Remote indicator light will flash slowly at first and then rapidly. Proceed with Step 4 under "Programming Universal Home Remote" to complete. Using Universal Home Remote Press and hold the appropriate Universal Home Remote button for at least half of a second. The indicator light will come on while the signal is being transmitted. Erasing Universal Home Remote Buttons To erase programming from the three Universal Home Remote buttons do the following: 1. Press and hold down the two outside buttons until the indicator light begins to flash, after 20 seconds. Do not hold the two outside buttons for longer than 30 seconds. 2. Release both buttons. The Universal Home Remote is now in the training (learning) mode and can be programmed at any time beginning with Step 2 under "Programming Universal Home Remote" shown earlier in this section. Individual buttons cannot be erased, but they can be reprogrammed. See "Reprogramming a Single Universal Home Remote Button" following this section. 181
