Overview
The NDX Local User Interface (LUI) includes 4 capacitive
touch buttons which can be used with the cover installed
or removed. When power is applied to the NDX, the external
buttons can be used to configure, calibrate, test, and monitor
the status of the device.
The LUI touch buttons area for sensing the touch of the finger
may not be exactly on top of the button symbol but more on
the screen area. This applies to the enclosure type NDX2 with
thick aluminum cover.
