electric shock, leakage-current or resistance measurements shall be
carried out (exposed parts are acceptably insulated from the supply cir-
cuit) 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 condi-
tions 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 mode.
