Wiedergabe bei abgenommenen GehÅ useoberteil Bei abgenommenen GehÅ useoberteil mu§ der Schalter 1430 kurzge- schlossen werde, damit das GerÅ t arbeitet. Achtung: Bei Betrieb mit geÅ¡ffnetem GehÅ use, 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.
