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.

The DC voltage is an actual reading measured with a high
impedance type voltmeter 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
instruments 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 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
voltmeter with no signal input. The
measurement value may vary
depending on the measuring
instruments used or on the product.
