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.
