CAUTION: For continued safe-
ty, replace safety critical com-
ponents only with manufactur-
er's recommended parts (refer
to parts list).
critical components. For con-
tinued protection against risk
of fi re, replace only with same
type and rating fuse(s). To re-
duce the risk of electric shock,
leakage-current or resistance
measurements shall be carried
out (exposed parts are accept-
ably 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 measure-
ment value may vary depending
on the measuring instruments
used or on the product.
