4.2.4 Digital reception quality
If you receive digital TV broadcasting (DVB) from your
own antenna (DVB-T) or use the TV tuner to receive digital
cable channels (DVB-C), you can verify the quality and
signal strength of a channel.
If the reception is poor, you can reposition your antenna
to try to improve the reception. For best results, contact a
specialised antenna installer.
