SERVICING
For servicing FW-R88, the set can be divided into two parts:
1.Except for the CD-R/W module all workshops can repair the set on component level.
2.The CD-R/W module can also be repaired at component level with the help of
COMPAIR Release 1.6 and higher.
With this tool the diagnosing of the set can be done in an interactive way. In the tool also the adjustment
procedure has been implemented. This is absolutely necessary in case the CDR MainBoard and/or
(CDR Loader) CDM is disconnected from the matched production combination.
Only designated workshops can perform these repairs.
Please send the complete FW-R88 to the designated workshop.

To avoid atmospheric interference all AM-measurements have to be carried out in a Faraday´s cage.
Use a bandpass filter (or at least a high pass filter with 250Hz) to eliminate hum (50Hz, 100Hz).
