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.
