parts list).
indicates safety critical com-
ponents. 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 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 mea-
surement value may vary depending on
the measuring instruments used or on
the product.
