CAUTION: For continued safety, replace safety
critical components only with manufacturer's
recommended parts (refer to parts list). indi-
cates safety critical components. For continued
protection against risk of fire, replace only with
same type and rating fuse(s). To reduce the
risk of electric shock, leakage-current or resis-
tance measurements shall be carried out
(exposed parts are acceptably insulated from
the supply circuit) before the appliance is
returned to the customer.
The DC voltage is an actual reading measured
with a high impedance type voltmeter with a
cassette loaded at playback mode. The mea-
surement value may vary depending on the
measuring instruments used or on the product.
Bias circuit DC voltage is measured while in
the record mode.
