After connecting the receiver that worked properly first. After several minutes, but no audio or video could be seen and lit in the display field "ASK" to, a code that is not listed in the manual and probably intended to mean that one customer service or similar Contact should. These things I have not done though, but the fact that this unrecoverable error occurs by laymen as early as 1 day, coaxed me only 2 stars (operating until the error was user-friendly and satisfying).
