The remote control was purchased as a replacement for a TV / video combination. The device over the Internet just worked. Unfortunately did not work even after the manual Teach two keys. A call to the hotline took some nerve (10 minutes on hold but fortunately for free). While the lady on the other end could not help immediately, but promised to report the problem to the second instance and to antwortetn within a week via e-mail. The answer came after 4 days and the remote control works.
