If the AEC input signal has excessive electrical noise superimposed on the signal, it is suggested that
jumpers JW1 to JW4 as appropriate be temporarily installed. If this improves the signal to noise ratio, the
jumper(s) should be left in. Excessive signal to noise ratio generally shows up as inconsistent AEC exposure
times at low mAs values.
It is the responsibility of the installer to determine the need for these jumper(s).
