CAUTION: For continued safety, replace safety critical components only with manufacturer's recommended
parts (refer to parts list). indicates 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 measurement value may vary depending on the measuring instru-

CAUTION: For continued safety, replace safety critical components only with manufacturer's recommended
parts (refer to parts list). indicates 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
resistance 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 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.

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, leak-
age-current or resistance mea-
surements 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.
