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 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.
