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 as the AM/FM signal generator is specified to the condi-
tions as shown in the list below. The measurement value may vary
depending on the measuring instruments used or on the product. The
value shown in ( ) is actual reading measured in the AM mode.
The DC voltage is an actual reading measured with a high impedance
type voltmeter. The measurement value may vary depending on the
measuring instruments used or on the product. Refer to the voltage
during PLAY unless otherwise specified; The value shown in ( ) is the
voltage measured at the moment of STOP.

The DC voltage is an actual reading measured with a high impedance
type voltmeter with a cassette loaded at playback mode. The measure-
ment value may vary depending on the measuring instruments used or
on the product. Bias circuit DC voltage is measured while in the record
mode.
