CAUTION: For continued safety, replace safety critical com-
ponents 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 resistance measurements shall be
carried out (exposed parts are acceptably insulated from the
supply circuit) before the appliance is returned to the cus-
tomer.
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.
