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.
