CAUTION: For continued safety, replace safety
critical components only with manufacturer's rec-
ommended 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 insu-

The DC voltage is an actual reading measured with
a high impedance type voltmeter as the AM/FM sig-
nal 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.
