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.
