CAUTION: For continued safety, replace safety criti-
cal components only with manufacturer's recom-
mended 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 insulat-
ed 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 instru-
ments 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 fol-
lowed by (REC) refers to the value during MD
RECORDING.
