Optimising the modulator

In some reception locations it is possible that a TV channel will be sent on the same or similar frequency as the video recorder.

Result: As soon as the video recorder is switched on, the reception quality for this or several other TV channels will decreased.

The following steps will show you how to change the pre-set 'transmission' (modulator) frequency on the video recorder.

What is a modulator?

This electronic component in the video recorder allows the device to transmit audio and video signals via the aerial cable. These signals can be received TV set just like TV channels.

What is an modulator frequency?

This frequency or channel indicates the frequency or channel on which the audio or video signal is transmitted.

4Select line 'OPTIMIZE FREQUENCY' using P ;q or P =r . Enter the new modulator frequency with the number buttons 0-9 .

Can the modulator frequency be changed automatically?
