CAUTION:
For continued safety, replace safety
critical components only with manufacturer's rec-
ommended parts (refer to parts list).
indicates
safety critical components. For continued protec-
tion against risk of fire, replace only with same type
and rating fuse(s). To reduce the risk of electric
shock, leakage-current or resistance measure-
ments 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 depend-
ing on the measuring instruments used or on the
product.
