External Input:
The E1103 can be connected to User electrodes, using connector J2.
The values of C1-C10 (sample capacitors) may require changing.
External Output:
The output of the QT1103-ISG can be accessed using J3. The tracks at LK1-4 can be cut to
disconnect the QT1103-ISG from U3, which is the IC used to used to drive the LEDs on the
E1103 Main Board.
If set to 'On': When touching multiple keys, only the LED associated with the key with the
strongest signal is lit.
If set to 'Off': When touching multiple keys, all associated LEDs will be lit.
