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 prod-
uct. Refer to the voltage during PLAY unless otherwise speci-
fied; The value shown in ( ) is the voltage measured at the
moment of STOP.

CAUTION: For continued safety, replace safety critical components 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 rat-

ing 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.
