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 mea-
surement value may vary depending on the measuring

CAUTION: For continued safety, replace safe-
ty critical components only with manufacturer's
recommended parts (refer to parts list). indi-
cates 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 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.

CAUTION: For continued safety, replace safety critical components only with manufacturer's recommended
parts (refer to parts list). 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 resis-
tance 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 mea-
surement value may vary depending on the measuring
