Press the “services” button on your remote control.
Move the highlighter down to “system setup” and press “OK” or simply press 4 on the remote.
Move the highlighter down to “languages and subtitles” and press “OK”, or press 3 on the remote.
Now you can turn audio description/subtitles on; insert a short beep so that when you’re channel-hopping and you land on a channel that is currently transmitting a programme with description you’ll hear the beep; highlight all programmes flagged as having description in white on the on-screen Electronic Programme Guide.
Once you’ve set everything to your liking, you will need to move the highlighter to “Save settings” then press “OK”.
This service is only available on SKY.
