yellowblue If you have trouble programming the Universal Transmitter, make sure that you have followed the directions exactly as described. The Universal Transmitter may not work with older garage door openers that do not meet current Federal Consumer Safety Standards. If you cannot program the transmitter after repeated attempts, refer to "Rolling Code Programming" later in this section or contact the Universal Transmitter manufacturer at 1-800-355-3515. Be sure to keep the original hand-held transmitter in case you need to erase and reprogram the Universal Transmitter. Note to Canadian Owners: During programming, the hand-held transmitter may automatically stop transmitting after one or two seconds. In this case, you should press and re-press the button on the hand-held transmitter every two seconds without ever releasing the button on the Universal Transmitter. Release both buttons when the indicator light on the Universal Transmitter begins to flash rapidly. Operating the Universal Transmitter Press and release the appropriate button on the Universal Transmitter. The indicator light comes on while the signal is being transmitted. If the hand-held transmitter appears to program the Universal Transmitter but does not open your garage door, and if the garage door opener was manufactured after 1996, the garage door opener may have a "rolling code" system. A rolling code system changes the code of the garage door opener every time you open or close the garage door. To determine if you have this system, press the button on the Universal Transmitter that you have programmed already. If the indicator light on the Universal Transmitter flashes rapidly for two seconds and then turns solid, the garage door opener has a rolling code system. In a rolling code system, the garage door motor head unit must be trained to the Universal Transmitter. 2-58
