226 Features several attempts. You should test every position for at least 20 seconds before trying another position. X Loading, stowing and features Keep transmitter button B on garage door remote control A pressed until indicator lamp : starts to flash rapidly. The programming has been successful if indicator lamp : flashes rapidly. X Release transmitter buttons ;, = or ? on the integrated remote control or transmitter button on the garage door remote control B. If indicator lamp : goes out after approximately 20 seconds and has not flashed rapidly: X Release transmitter buttons ;, = or ? on the integrated remote control or transmitter button on the garage door remote control B. X Repeat the procedure for the other transmitter buttons. When doing so, vary the distance between the garage door's remote control and the transmitter buttons in the rear-view mirror. some U.S. gate operators are designed to "time-out" in the same manner. If you live in Canada or have difficulties programming the garage door opener (regardless of where you live) when using the programming steps (see above), proceed as follows: X Press transmitter button (;, = or ?) and hold it down during the following steps until the setup has been completed successfully. X At the same time, press transmitter button B of the garage door remote control for two seconds, then release it for two seconds, then press it again for two seconds. X Repeat this sequence on transmitter button B of the garage door remote control until the frequency signal has been learned. X If the setup procedure is successful, indicator lamp : flashes once slowly and goes out after a few seconds. X Continue with the other programming steps (see above). Problems when programming If you have problems when programming the integrated remote control, please note the following: Rcheck i If the garage door system works with a rolling code, you must synchronize the remote control integrated into the rearview mirror with the garage door system receiver after programming. You will find further information in the garage door opening system's operating instructions, e.g. the sections on "Synchronizing the transmitter" or "Registering a new transmitter". You can also call the hotline mentioned above. Notes on programming the remote control Canadian radio frequency laws require transmitter signals to "time-out" (or quit) after several seconds of transmission. This may not be long enough for the integrated signal transmitter to pick up the signal during programming. Similar to this Canadian law, the transmitter frequency of garage door remote control A (which can usually be found on the rear of the remote control). The integrated remote control is compatible with equipment that operates in the frequency range 280 to 390 MHz. Rreplace the batteries in garage door remote control A. This increases the likelihood of garage door remote control A sending a strong and precise signal to the integrated remote control on the rear-view mirror. RWhen aiming the garage door remote control at the transmitter buttons on the rear-view mirror, hold garage door remote control A at differing distances and angles
