CAUTION : For continued
safety, replace safety criti-
cal components only with
manufacturer’s recom-
mended parts (refer to
parts list).
Indicates safety critical
components. 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 circuit) be-
fore the appliance is re-
turned to the customer.
•
DC voltages are as
measured with a high
impedance voltmeter.
Values may vary slightly
due to variations be-
tween individual instru-
ments or/and units.
