If the WiFi scanner no longer responds to anything and, for example, only shows a gray screen, the following procedure can be performed.


  1. Press the red button once (do not hold)
  2. Then choose the 'Safe Battery Swap' option
  3. Then remove the battery (with the 2 buttons (left and right) at the bottom of the scanner)
  4. Now simultaneously press the 'scan' button (the yellow 'button' (trigger) with which you scan barcodes) and the red button.
  5. The scanner will now be restarted
  6. The battery can now be pushed back into the scanner.
