If scanning was unsuccessful, the user will hear two short beeps, the LEDs will illuminate red,
and the message
Failed reading
will display. If this is the case, the user should point the KDC at
the barcode and press the scan button while trying the following suggestions:
⚫ Modify the angle of the KDC in relation to the barcode, making the angle more wide or
narrow as needed. (Laser Model)
⚫ Modify the distance between the barcode and the KDC, moving closer or further away
as needed.
⚫ Check the option settings defined in the KDC menu section and change options as
needed.
⚫ Check to see that the barcode’s width does not exceed the light beam’s width, and vice
versa.
