Repeat the press/hold/release sequence a second time, and depending on the brand of the garage door opener, or other rolling code device, repeat this sequence a third time to complete the programming. The Universal Home Remote should now activate your rolling-code equipped device. To program the remaining two Universal Home Remote buttons, begin with Step 2 of "Programming Universal Home Remote." You do not want to repeat Step 1, as this will erase all previous programming from the Universal Home Remote buttons. 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.

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. 2-54
