CAUTION:
For continued safety, replace
safety critical components only with manufac-
turer'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 cus-
tomer.
The DC voltage is an actual reading mea-
sured 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 volt-
age measured at the moment of STOP. The
voltage followed by (REC) refers to the value
during MD RECORDING.
