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...
2-4-2. Switch, Indicators, Audio and Communication Circuit Check by an Oscilloscope
1. Connect the pin 7 of CN1 on the AU-254 board to the + terminal of the power supply, and the pins 1 and 2 of CN1 to GND of the power supply. Use the modified RK-8XXX cable to facilitate the check required. (Refer to step1 in 2-4-1. Switch, Indicators and Audio Circuit Check.) 2. Connect the pin 4 of CN1 on the AU-254 board to GND of the power supply. 3. Set a DC out voltage to +15 V, and turn on the power switch. 4. Two seconds later, all response indicators (D1 through D6 on the SW-952 board) flash. 5. Disconnect the pin 4 of CN1 on the AU-254 board from GND of the power supply. 6. With transmitting �55H� code from the pin 3 of IC1 (TxD terminal) on the SW-952 board, all response indicators light. With all response indicators flashing, that is, without lighting, it is abnormal. Check the signals between the pin 1 of IC1, the pin 3 of IC1 and the pin 4 of CN1 on the AU-254 board. 7. (a) Switches and indicators check Perform the same step as step 7(a) in 2-4-1. Switch, Indicators and Audio Circuit Check. (b) Audio circuit check Perform the same step as step 7(b) in 2-4-1. Switch, Indicators and Audio Circuit Check. (c) Communication circuit check Using an oscilloscope, confirm that �55H� code is transmitted to the pin 4 of CN1. With transmitting �55H� code to the pin 4 of CN1, it shows the following waveform on the oscilloscope.

2-4-3. Indicators, Audio and Communication Circuits Check by EA-80 connected to LLC-8000
1. Press the POWER switch on the LLC-8000 to turn the total LLC-8000 system on. (Do not press the ATTEND button on the LLC-8000. Not pressing the ATTEND button does not light the indicator located at the left-above the monitor button on the LLC-8000.) 2. Check switches, indicators and audio circuit by the same steps as steps 3 through 7 in 2-4-1. Switch, Indicators and Audio Circuit Check. 3. Communication circuit check. When the communication is established, the indicator that shows the student unit, EA-80, being checked and located at the left-above the monitor button on the LLC-8000, lights. 4. Press the POWER switch on the LLC-8000 to turn the system off.
