CAUTION: For continued safety, replace safety criti-
cal components only with manufacturer's recom-
mended 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 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.
