If the TV set and the video recorder are only connected with an
aerial cable - rather than with an additional scart cable - it may
happen that in certain reception locations the modulator fre-
quency of the video recorder is occupied by a TV channel. As
soon as the video recorder is switched on, the reception quality
of the TV picture deteriorates.The following steps will show you
how to overcome this problem.

image on this frequency

the remote control and the
