CAUTION: For continued safety,
replace safety critical compo-
nents only with manufacturer's
recommended parts (refer to
parts list). indicates safety
critical components. For contin-
ued protection against risk of
fire, replace only with same type
and rating fuse(s). To reduce the
risk of electric shock, leakage-
current or resistance measure-
ments 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 measurement value
may vary depending on the
measuring instruments used or
on the product. Bias circuit DC
voltage is measured while in the
record mode.
