to parts list). indicates safety critical components. For
continued protection against risk of fire, replace only with
A
same type and rating fuse(s). To reduce the risk of electric
shock, leakage-current or resistance measurements shall

The DC voltage is an actual reading measured with a high
impedance type voltmeter. The measurement value may
X25-
CN4
vary depending on the measuring instruments used or on
the product. Refer to the voltage during PLAY unless other-
2/3
wise specified; The value shown in ( ) is the voltage mea-
sured at the moment of STOP.
