DC voltages are as measured with a high
impedance voltmeter. Values may vary
slightly due to variations between
individual instruments or/and units.

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 retuned to the customer.
