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-cur-
rent or resistance measurements
shall be carried out (exposed parts

are acceptably insulated from the
Digitron not display
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 instru-
ments used or on the product.
