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.
