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. The measurement value
may vary depending on the measuring instruments used
or on the product. Refer to the voltage during
RECORDABLE 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.
