The purchased manual is an high-quality scan of the original JVC paper-based Service Manual. The Service Manual includes the Owner´s Manual, so you do not have to buy both of them.
 ;
It paid to find this Service Manual, couldn't find it anywhere else. Exactly what I wanted. Received within 24 hours.
;
Complete manual with clear schematic diagrams and printed circuit board layouts of two variants of the headset and the transmitter an old and a new version.
Also shows how the headset and the transmitter is opened and how transmitter and receivers can be adjusted and where to measure.
I had no problems to repair the headset using this service manual.
;
Excellent printing quality. A complete and very useful manual with all details.
;
This is a great site. I placed my order and by the next am it was available for download. Had some problems with some missing copy on some pages. Once I brought the error to the OMC's attention, the issue was resolved. I'll come back again.
