CAUTION : For continued safety,
replace safety critical compo-
nents 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.
