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.
