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.
