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.
