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.
