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.
