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 mode.
