safety critical components. For contin-
ued 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 insulat-
ed 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 depend-
ing on the measuring instruments used
or on the product.
