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 indi-
vidual instruments or/and units.
