indicates 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 measure-
ments 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 mea-
sured with a high impedance type voltmeter
with no signal input. The measurement
value may vary depending on the measur-
ing instruments used or on the product.
