(refer to parts list).
indicates safety
critical components. For continued pro-
tection against risk of fire, replace only
with same type and rating fuse(s). To
reduce the risk of electric shock, leak-
age-current or resistance measurements
shall be carried out (exposed parts are
acceptably insulated from the supply cir-
cuit) 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 mea-
surement value may
vary depending on the
measuring instruments
used or on the product.
