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...

Final check after repair
Final check after repair The �nal check after repair, describes the activities that are needed to ensure the product will be returned in perfect condition to the customer. The contents is: AC leakage test. Check product information. Restore the setup and check connections, picture and sound. Final cleaning of the product. PIN-code setting.
AC leakage test
The scope of the test is, to check the antenna terminals and other exposed metal parts for AC leakage. 1. 2. 3. 4. Remove the line cable from the AC source (the wall outlet). Place a jumper across the two AC plugs prongs. Use a multi-meter, set for measurements in the ohm-area. Place one lead from the multi-meter on the AC plug and place the other lead on each of the exposed metal parts, that is antenna connections and other exposed metal parts on the rear panel of the product. The resistance during these measurements must be of 1 Mega Ohm or more. If resistance is below 1 Mega Ohm, this indicates an abnormal situation and corrective actions must be taken.

Insulation test Each set must be insulation tested after having been dismantled. Make the test when the set has been reassembled and is ready to be returned to the customer. Flashovers must not occur during the testing procedure! Make the insulation test as follows: Short-circuit the two pins of the mains plug and connect them to one of the terminals of the insulation tester. Connect the other terminal to ground on the aerial socket. NOTE! To avoid damaging the set it is essential that both terminals of the insulation tester have good contact. Slowly turn the voltage control of the insulation tester until a voltage of 1.5 kV and max. 10mA is obtained. Maintain that voltage for one second, then slowly turn it down again. Insulation test at the customer Remove the mains cable from the wall outlet. Place a jumper across the two AC plug prongs. Use a multi-meter, set for measurements in the Ohm-area. Place one lead from the multi-meter on the AC plug and place the other lead on ground at the Power Link plug. The resistance during this measurement must be of 1 Mega Ohm or more. Resistance measured below 1 Mega Ohm indicates an abnormal situation and corrective action must be taken.
