Reducing picture disturbance - optimizing
the modulator
You may experience picture disturbance if you have not used
a scart cable to connect your video recorder and TV. This is
because another TV station in your reception area may
already be using UHF-channel CH35 or 583MHz. When the
video recorder is switched on, the picture quality of some TV
channels that you receive on the TV will be poor.
You may optimize the picture quality by changing the
modulator frequency (591MHz or UHF channel 36).
1
Switch on the TV set and select the programme number
for the video recorder playback (see your TV operating
manual).
2
Make sure that there is no cassette in the video recorder.
3
First press and continue to hold the
remote control, and then press and hold the
on the video recorder. Hold both in for several seconds
until, for example, 'M583' appears on the video recorder
display.
The video recorder will transmit a test picture on
UHF-channel 35(or frequency 583Mhz).
