Additional info: There are at least four versions of this receiver known to me: The M, W, K and
Asian versions. The K (USA) and Asian versions feature a video output jack
for TV reception. Also, the Asian version has a "TV.MO" button instead of the
"BEEP" button. The TV.MO function is not documented in the english manual.
