CAUTION: For continued safety,
replace safety critical components only
with manufacturer's recommended
parts (refer to parts list).
indicates
safety critical components. For contin-
ued 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
instruments used or on the product.
Refer to the voltage during PLAY with
DASC OFF(at the normal speed)
unless otherwise specified; The value
shown in ( ) is the voltage measured
at the moment of STOP.
