CAUTION: For continued safety,
replace safety critical compo-
nents only with manufacturer's
recommended parts (refer to

parts list).

indicates safety criti-
cal 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 carried out (exposed
parts are acceptably insulated
from the supply circuit) before the
appliance is returned to the cus-
tomer.
The DC voltage is an actual read-
ing measured with a high imped-
ance type voltmeter with no sig-
nal input. The measurement
value may vary depending on the
measuring instruments used or
on the product.
