Great copy of the manual, has all information required for servicing,
;
I work at an authorized service center and I can tell if a manual is as it should be. This one is. It may be a scan, but a very good one at that. The interesting part for me was the curcuit diagram which was scanned at high quality, making it as good as the original. I will definitely be back as a customer. I need not say this, but I will: the price was the best. Thank you owner-manuals.com .

Thank you very much for this Service Manual, it helped us a lot to repair the M-4318!
...BUT: The parts list is missing and the free parts katalog on web isn't complete, so now we don't know the part numbers of the defect parts :(
We had to build them out of a working machine, and need the numbers to reorder the missing parts now.

1-4. Function of Internal Switch
AT-88 board � S201 (MIC LEVEL 1 0 dBu/-20 dBu) � S301 (MIC LEVEL 2 0 dBu/-20 dBu) Used to set the output level at the MIC OUT CH1/CH2 connector to �0 dBu� or �-20 dBu�. Factory-setting is �0 dBu�. (0 dBu=0.775 Vrms) � S1001 (CCU No.) This switch is mainly used for the CCU number setting. The CCU number of 1 to 96 can be set in binary coded decimal (BCD) using the switches 1 to 8 of S1001. The switches 1 to 4 determine the number of units and 5 to 8 determine the number of tens. For each digit, the number of 0 to f can be assigned. The numbers a to f, however, become invalid. (Example)
