CAUTION:
For contin-
ued safety, replace safe-
ty critical components
only with manufacturer's
recommended parts
(refer to parts list).
indicates safety critical
components. For contin-
ued protection against
risk of fire, replace only
with same type and rat-
ing 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 mea-
suring instruments used
or on the product.
