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.
