Keep in mind that the application running on NEO can dictate how the LED operates.
Review the documentation provided with your application to determine LED behaviour.
The scanner also overrides LED behaviour. The table below describes what the various LED
colours indicator when a scan is activated – a scanner button is pressed or the scanner trigger
is pulled.
If the unit is attached to an external power supply, the hand-held LED reflects the battery
charge status.

Audio Indicators
The audio receiver provides a variety of sounds when a key is pressed, a keyboard character
is rejected, scan input is accepted or rejected, an operator’s entry does not match in a match
field or the battery is low. To specify how you want your NEO to respond under various con-
ditions, refer to “Volume And Sound Properties” on page 90.
