CAUTION : For continued safety, replace safety critical components
only with manufacturer's recommended parts (refer to parts list).
Indicates safety critical components. To reduce the risk of electric
shock, leakage-current or resistance measurements shall be carried
out (exposed parts are acceptably insulated from the supply circuit)
before the appliance is returned to the customer.
•DC voltages are as measured with a high impedance voltmeter.
Values may vary slightly due to variations between individual
instruments or/and units.

CAUTION : For continued
safety, replace safety critical
components only with
manufacturer's recommended
parts (refer to parts list).
Indicates safety critical com-
ponents. To reduce the risk of
electric shock, leakage-current
or resistance measurements
shall be carried out (exposed
parts are acceptably insulated
from the supply circuit) before
the appliance is returned to the
customer.
•DC voltages are as measured
with a high impedance volt-
meter. Values may vary
slightly due to variations be-
tween individual instruments
or/and units.
