For continued protection against risk of fire,replace only with same type and rating fuse(s). To reduce the risk ofelectric shock, leakage-current or resistance measurements shall becarried 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 impedancetype voltmeter as the AM/FM signal generator is specified to the condi-tions as shown in the list below. The measurement value may varydepending on the measuring instruments used or on the product. Thevalue shown in ( ) is actual reading measured in the AM mode.
