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.
