Features transmitter button B on the garage door remote control. If indicator lamp : goes out after approximately 20 seconds and has not flashed rapidly: X 399 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 a "break" (or interruption) of the transmission signals a few seconds after broadcasting. Therefore, these signals may not last long enough for the integrated remote control to recognize the signal during programming. Comparable with Canadian law, some U.S. garage door openers also have a built-in "interruption". 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 Problems when programming If you have problems when programming the integrated remote control, please note the following: RCheck 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 devices that operate at frequencies between 280 and 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 programming, hold garage door remote control A at varying distances and angles from the transmitter button which you are programming. Try different angles at a distance of 2 to 12 inches (5 to 30 cm) or the same angle at different distances. RIf there is another garage door remote control for the same device, perform the programming steps again using the remote control. Before performing these steps, Z Loading, stowing and features Release transmitter buttons ;, = or ? on the integrated remote control and transmitter button B on the garage door remote control.

When doing so, vary the distance between the garage door's remote control and the transmitter buttons in the rear-view mirror. 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 saved. 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).
