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
frequency of the video recorder is occupied by a TV channel.
Result: 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.
