Optimizing the modulator

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.

What is a modulator?

 

The purpose of this electronic assembly inside your

 

video recorder is to pass on the picture and sound

 

information read in from the video tape via an aerial

 

cable like a TV signal to the TV set.The modulator fre-

 

quency determines the frequency range in which these

TIP

signals are transmitted.

1Switch the video recorder on and make sure there is no cassette in the video recorder

2Press simultaneously the STOP button h on

the remote control and the STOP/EJECT ? button on the front of the video recorder until the modulator frequency of the set appears in the display (e.g.:“M583” for 583 MHz)

3The video recorder will now transmit a test image on this frequency

4Use =P- or ;P+ to select the option “OPTIMIZE FREQUENCY” and enter a new frequency with the number buttons 0-9

Which modulator frequency should I enter?

You can also make the video recorder search automatically for an appropriate frequency. To do so,

simply hold down the button P. As soon as a free

frequency has been found,it will be shown in the display. PROBLEM

5Tune the programme number of your TV set allocated for video use to the new modulator frequency until you see the test image sharply and in colour
