MORE INFORMATION ABOUT YOUR VCR
VCR DIGITAL DISPLAY
NOTE: 
SELECTING THE OUTPUT FROM THE VCR
If your VCR is connected to your TV with a scart lead, when you start to play a video tape the 
VCR will automatically switch its output so that playback picture is shown on the TV.
In this case ‘VCR’ will appear on the VCR display.
You can manually override this by pressing 
[TV/VCR]
 on the remote control. Now the TV 
broadcast channel will be seen on the TV screen and ‘VCR’ will disappear from the VCR 
display.
Pressing 
[TV/VCR]
 again will return the TV picture to the playback picture.
Some models do not have all the features shown, therefore, they will not appear on the 
display.
