Service Information
Product
RR 430 CD
Possible complaint:
The contacts (7-5) of switch SW 201B become charred so that they do no longer
contact.
Reason:
The switching contact provides the voltage for both the CD servo system and the
audio power amplifier.
Cure:
Connect the emitter of Q 201 directly to the voltage supply. The switch is only
used for controlling the base current which is much lower than the emitter current.
Fig. 1 (see page 2)

Possible complaint:
Cassette compartment door jams or does not open.
Reason:
1.When applying too much pressure when closing the cassette compartment
door, the door may get jammed at the lower edge of the cabinet front below the
display window.
2.Due to the tolerable differences in the length of the Play button lever it may
happen that the lever slips out of its guide thus blocking the eject mechanism.
All other functions work correctly.
Cure:
To 1: Modification of the cabinet front.
To 2: Lengthened Play button lever by putting a metal clip on it.
Introduction in the factory:
1 and 2: at the end of August/99
Workshop:
To 1: Replace the cabinet front if necessary.
To 2:1. Open the cabinet on the back.
2. Undo the screws of the tape deck.
3. Take the tape deck out.
4. Put the metal clip on the Play button lever.
