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.
