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.
