Hitachi CX-200 - Specifications; Maintenance

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 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.

* Specifications are subject to change without notice for
performance improvement.
Check that exposed parts are acceptably insulated from
the supply circuit before returning the instrument repaired
to the customer.
¢ Checking method
INSTRUMENT
(Exposed part)
Measure the resistance value between the both poles of
attachment cup (Power supply plug) and the exposed
parts (Parts such as Knob, Cover, etc. where the cus-
tomer is easy to touch.) and check that the resistance
value is 500 kohms or more.
MAINTENANCE
M@ Clean cabinet and panels when dirty
Clean off dirt on the surfaces with a dry cloth. Never
use thinners, benzene or alcohol since these will
damage the surface finish.
Insulation tester (DC 500V)
