Servicehinweise

CD-Laufwerk
Beim Ausbau des CD-Laufwerks muß nach Abziehen der Steck-
verbindungen eine Büroklammer über die Kontakte der Steck-
verbindung 1 (siehe Ausbau) gesteckt werden, um eine Zerstörung
der Laserdiode durch statische Aufladung zu vermeiden.
Wiedergabe bei abgenommenen Gehäuseoberteil
Bei abgenommenen Gehäuseoberteil muß der Schalter 1430 kurzge-
schlossen werde, damit das Gerät arbeitet. Achtung: Bei Betrieb mit
geöffnetem Gehäuse, Laservorschriften (siehe Service Manual
"Sicherheit") beachten.

Service Hints

CD Mechanism
When removing the CD mechanism a paper clip must be attached at
the flexprint contacts 1 (see Disassembly Instructions) to avoid distroying
the laser diode by electrostatic charges.
Playback with removed Cabinet Top
With removed cabinet top switch 1430 must be shorted so that it is
possible to operate the set. Attention: Take care of the Laser Safety
Instructions (see Service Manual "Safety") when operating the
set with opened cabinet.
