CAUTION: For continued safety, replace safety critical
components only with manufacturer's recommended
parts (refer to parts list). indicates safety critical com-
ponents. 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

before the appliance is returned to the customer.
The DC voltage is an actual reading measured
with a high impedance type voltmeter. The mea-

CAUTION: For continued safety, replace safety critical components only with manufacturer's recom-
mended 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 mea-
surement value may vary depending on the measuring
instruments used or on the product.
