Servicing
For servicing CDR570, the set can be divided into two parts.
1. The display board 1002 and the I/O board 1004 have to be repaired
at component level. The power supply unit 1003 is available as a
spare part, but can also be repaired at component level.
2. The CDR module (containing the CDR loader 81, CDR main board
1001 and loader bracket 82, 83) will be exchanged completely in
case of failure. This complete CDR module is available as spare
part. Defective modules have to be returned for central repair.
Also available: Circuit Description "The Basics of Compact Disc
Recordable/Rewritable". Service code number 4822 725 25242.
