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.
