Compact Disc Recorder
SERVICING
For servicing CDR79x the set has to be divided into two parts:
1. Except for the CD-R/W module all workshops can repair the set on component level.
The Switched Mode Power Supply unit will be exchanged completely in case of a failure.
2.The CD-R/W module can only be repaired on component level with the help of ComPair.
With this tool diagnosing of the set can be done in an interactive way. In this tool also the adjustment procedure has
been implemented. The adjustment is absolutely necessary in case the CDR-Main Board and/or CD drive (CDR Loader)
is disconnected from the matched production combination.
Only designated workshops can perform these repairs!
Please send the complete set to the designated workshop.
