ical 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 insu-
lated 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 prod-
uct.
