CAUTION:
For continued safety, replace safety
critical components only with manufacturer’s
recommended parts (refer to parts list). indi-
cates safety critical components. For continued
protection against risk of
fi
re, 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.
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 measuring instruments used
or on the product.
