The purchased manual is an scan of the original Panasonic paper-based Service Manual. Unfortunately the contrast is not perfect, but I am satisfied anyway!
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.
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.
