CAUTION : For continued safety, replace safety critical compo-
nents 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.
