I liked the product. I would use their sevices again.

I Recently purchased yet another Service Manual from Owner-Manuals.com, this time for a Sony EVS700ES/UB Videocassette Recorder. The Manual was available for upload within two hours and is an Extremely Good copy, as some of this I was able to enlarge to get even better detail.
Once Again, Very happy with the result!

A good and useful manual. With these, We was abled to isolate and pin point the component that was causing the problem. The total time spent in troubleshooting is very much reduced.

SAFETY PRECAUTIONS
The following precautions should be observed when servicing. 1. Since many parts in the unit have special safety-related characteristics, always use genuine Hitachi�s replacement parts. Especially critical parts in the power circuit block should not be replaced with other makers. Critical parts are marked with _ in the circuit diagram and printed wiring board. 2. Before returning a repaired unit to the customer, the service technician must thoroughly test the unit to ascertain that it is completely safe to operate without danger of electrical shock.
