CAUTION : For continued safety, replace safety critical components onlywith 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 (exposedparts are acceptably insulated from the supply circuit) before the applianceis 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/andunits.
