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.

CAUTION: For continued safety,
replace safety critical components only
with manufacturer's recommended parts
(refer to parts list).
indicates safety
critical components. For continued pro-
tection against risk of fire, replace only
with same type and rating fuse(s). To
reduce the risk of electric shock, leak-
age-current or resistance measure-
ments 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
voltmeter with no signal input. The mea-
surement value may vary depending on
the measuring instruments used or on
the product.
