recommended parts (refer to parts list).
indi-
cates 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 insulated from
the supply circuit) before the appliance is
returned to the customer.
R
The DC voltage is an actual reading measured
L
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 oth-
R
erwise specified; The value shown in (
) is
the voltage measured at the moment of STOP.
