We call this error the "sensor error" and it occurs when the scanner cannot communicate with the yellow selector pin, most often because of a loose connection. Below are some things that you can try when the error occurs:

• Remove the scanner from the machine like when replacing batteries. Ensure that the white plug is well attached, and that no cables that are broken.

Does the above not, contact Beefit Support at: support@benefittech.dk, type "error" in the subject field.
