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 elec-
tric 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 sig-
nal input. The measurement value may vary
depending on the measuring instruments used or
on the product.
