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.

Good quality, all schematics of few of models. There is also short form of user manual and regulation manual.
;
Perfect copy of the service manual. you can enlarge every page, and it comes up
with all details.

It´s very very nice manual with all, what i need. Original in good quality. Very fast business. Very much thanks...
7. The voice of the caller cannot be heard (incoming call).
Can the base and handset be connected? OK The 1kHz 97.5mV sine waveform is applied to TEL-line of the base, can the 1kHz sine waveform from the Q1 collector be fed? OK Check whether there is the 1kHz sine waveform at Pin13 of IC1. OK Check whether there is the 1kHz sine waveform at Pin9 of IC1. OK TX output signal from the base is detected by the liner detector, can the 1kHz 3kHz Dev. sine waveform be fed? OK Check whether there is the 1kHz sine waveform at Pin16 of IC501. OK Check whether there is the 1kHz sine waveform at Pin19 and 20 of IC501. OK Check whether there is the 1kHz sine waveform during for Pin1 and 2 of J501. OK NG NG Check IC501 and Pin17~20 peripheral circuits of IC501. NG Check IC501 and Pin15~16 peripheral circuits of IC501. NG NG Check IC1 and Pin9~11 peripheral circuits of IC1.
