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 unless other-
wise specified; The value shown in ( ) is the voltage mea-
sured at the moment of STOP.
CAUTION:
For continued safety, replace safety critical com-
ponents only with manufacturer'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
customer.
