reduce the risk of electric shock, leakage-current or
resistance measurements shall be carried out (exposed

before the appliance is returned to the customer.
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 RECORD-
ABLE MD PLAY unless otherwise specified; The value
shown in ( ) is the voltage measured at the moment of
STOP. The voltage followed by (REC) refers to the
value during MD RECORDING.
