CAUTION: For continued safety, replace safety critical compo-
nents 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-cur-
rent 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 mea-
surement 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.
