CAUTION : For continued safety, replace safety critical compo-
nents 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 voltme-
ter. Values may vary slightly due to variations between indi-
vidual instruments or/and units.
