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 imped-

ance voltmeter. Values may vary slightly due to
variations between individual instruments or/and
units.
