audio channels.
These are used by the satellite programme pro-
viders in different ways: for mono, stereo and
multi-channel sound of TV broadcasts and for radio
broadcasts.

For the satellite channels shown in the enclosed
programme list, the frequencies of the TV audio
channels are already preprogrammed.

ge an audio option is explained in the chapter 
”Changing Programme Position Settings”.
