6.3.1 The MODE key
Automatic source selection can be overruled by using the MODE key. Each time the MODE key is
pressed, the next source is selected in the order:
Radio -> CD-changer -> Cassette -> External.
Cassette mode can be selected only if a tape is present in the cassette deck.
External mode can be selected only if a connector is present in the external audio jack.
6.3.2 CD-changer mode
The presence of a CD-changer is asserted during the power-on phase of the radio. The CD-changer can
only be selected if the CD-changer was present during power-on. The CD-changer mode can only be
selected with the MODE key.
