Super Anleitung. Ordentliche Auflösung. Das ganze noch in Deutsch wäre zu schön. Alle Datenblätter sind sauber Kopiert und alle Leitungswege sind sauber ausgeführt
About the service it's very fast and reliable. About the manual the quality is high enough to read even the tiniest details on the wiring diagrams so you can't ask much more than that, let it alone for a manual of a product from 20 years ago. Thank you, very satisfied.
The downloaded quality was as good as the orignial

WARNING
Check that exposed parts are acceptably insulated from the supply circuit before returning the repaired instrument to the customer.
CHECKING METHOD
Measure the resistance value between the both poles of attachment cup (power supply plug) and the exposed parts (parts such as covers etc. where the customer can easily touch) and check that the resistance value is 500k ohms or more.
SAFETY PRECAUTIONS
The following precautions should be observed when servicing. Since many parts in the unit have special safety related characteristics, always use genuine HITACHI replacement parts. Especially critical parts in the power circuit block should not be replaced with other makers. Critical parts are marked with a ! in the circuit diagram and printed wiring board. 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.
