CAUTION: For continued safety, replace safety critical com-
ponents only with manufacturer's recommended parts (refer
to parts list).
h j
continued protection against risk of fire, replace only with
same type and rating fuse(s). To reduce the risk of electric
f b
shock, leakage-current or resistance measurements shall be
carried out (exposed parts are acceptably insulated from the
6 3 1 5 1 5 0 8 9
k 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
e c
instruments used or on the product.
