The DC voltage is an actual reading measured with a high
3
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 (

continued protection against risk of
fire, replace only with same type and
rating fuse(s). To reduce the risk of
electric shock, leakage-current or
resistance measurements shall be
carried out (exposed parts are
acceptably insulated from the supply
circuit) before the appliance is
returned to the customer.
