6.2Preprogrammation 6.2.1 General
On MAC broadcasting services the two numbers of the digital sound channels which are set when you select "normal" or "favoured" are preprogrammed instead of the two audio fre- quencies.
This is why the audio column of the table reads
dig n# f#
(# meaning one of the numbers from 1 to 8).
