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.
