There can be a number of reasons for this:

• a particular program running
• a particular physical position
• some objects reflect the light back to the sensor
• some objects are in the sensor's scanning field

Try to re-position, remove objects and/or close certain programs.

Unplug/plug-in the sensor for recalibration. If this does not help creating a ticket.

Please contact Neonode Support team for further information.
