The DC voltage is an actual reading

measured with a high impedance

type voltmeter as the AM/FM signal

generator is specified to the condi-

tions 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.

CAUTION: For continued safety,

replace safety critical components only

ued protection against risk of fire,

replace only with same type and rating
