CAUTION : For continued safety, replace safety critical components only with manufacturer's recom-
mended 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.
