The DC voltage is an actual reading measured with a high impedance type volt-
meter as the AM/FM signal generator is specified to the conditions as shown in the
list below. The measurement value may vary depending on the measuring instru-
ments used or on the product. The value shown in ( ) is actual reading measured
in the AM mode.
CAUTION: For continued safety, replace safety critical components only with manu-
facturer's recommended parts (refer to parts list). indicates safety critical compo-
nents. 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 mea-
surements shall be carried out (exposed parts are acceptably insulated from the sup-
ply circuit) before the appliance is returned to the customer.
