GRUNDIG Service1 - 3 Allgemeiner Teil / General Section KM 12 Servicehinweis Bei Ausbau des CD-Laufwerks mu§ vor Ab- ziehen der Steckverbindungen eine Schutz- lštstelle auf der Leiterplatte der Lasereinheit angebracht werden, um eine Zerstšrung der Laserdiode durch statische Aufladung zu vermeiden. Beim Einbau einer neuen Lasereinheit mu§ nach Einstecken der Steckverbindungen die werkseitig angebrachte Schutzlštstelle ent- fernt werden. Service Hint Before detaching the plug-in connections when removing the CD drive mechanism a protective solder joint must be provided on the circuit board of the laser pick-up to avoid the laser diode being destroyed by static charges. When fitting a new laser pick-up the protec- tive solder joint provided in the factory must be removed before inserting the plug-in con- nections.
