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 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 measur-
ing 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.
