CAUTION: For continued safety, replace safety critical components only with manu-
facturer's recommended parts (refer to parts list). A 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
measurements shall be carried out (exposed parts are acceptably insulated 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 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 made.
