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 prod-
uct. Refer to the voltage during RECORDABLE MD PLAY
unless otherwise specified; The value shown in ( ) is the volt-
age measured at the moment of STOP. The voltage followed
by (REC) refers to the value during MD RECORDING.
