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
BeiabgenommenenGehäuseoberteil muß der Schalter 1430 kurzge-
schlossenwerde,damitdasGerätarbeitet.Achtung:BeiBetriebmit
geöffnetem Gehäuse, Laservorschriften (siehe Service Manual
"Sicherheit") beachten.
Service Hints
CD Mechanism
When removing the CD mechanism a paper clip must be attached at
theflexprintcontacts1(seeDisassemblyInstructions)toavoiddistroying
the laser diode by electrostatic charges.
Playback with removed Cabinet Top
With removed cabinet top switch 1430 must be shorted so that it is
possibletooperate theset.Attention:Take care ofthe LaserSafety
Instructions (see Service Manual "Safety") when operating the
set with opened cabinet.
