This is a good quality scan of the Operation & Maintenance (Service) Manual for the PAL version of this high-band broadcast umatic, BVU-800P
All schematics and lineup procedures appear to be included in this one manual AFAICT.
The file size is just over 113 MB which gives an idea of the quality and number of pages.
All of the schematics, which contain some fairly small print, are easily readable when you zoom into the page.

;
Perfect copy of the service manual. you can enlarge every page, and it comes up
with all details.

KMC-35/36
CIRCUIT DESCRIPTION
Hot Microphone Function
In the Hot microphone state, only microphones whose PTT switch is pressed can send modulation signals in the environment in which several microphones are connected to the transceiver in parallel. In the Normal microphone state, if the PTT switch on one of the microphones is pressed, modulation signals are sent from all microphones.
â� Circuit description
Hot microphone operation can be performed by cutting the jumper (JP1). If the jumper is not cut (Normal microphone state), bias voltage is always applied to the microphone element (Q3 is always ON) and if the microphone mute of the transceiver to which the KMC-35/36 is connected is released, modulation signals can be sent even when the microphone PTT switch is not pressed. If the jumper is cut (Hot microphone state), bias voltage is applied to the microphone element only when the PTT switch is pressed (Q3 turns ON only when the PTT SW is pressed), and modulation signals cannot be sent when the microphone PTT switch is not pressed.
