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.
