safety critical components. For 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 car-
ried out (exposed parts are acceptably insulated from the supply circuit)
before the appliance is returned to the customer.
The DC voltage is an actual reading measured with a
high impedance type voltmeter with no signal input. The
measurement value may vary depending on the mea-
suring instruments used or on the product.
