parts list).
ponents. 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 resis-
tance measurements shall be carried out
(exposed parts are acceptably insulated
from the supply circuit) before the appli-
ance is returned to the customer.
The DC voltage is an actual reading mea-
sured with a high impedance type volt-
meter with no signal input. The measure-
ment value may vary depending on the
measuring instruments used or on the
