When the device is switched to Acuity Speech mode it shows the Start screen. In this screen there’s a full page live view of the tableau. The yellow marker indicates the scan area. The device scans documents up to A4 or US letter size. When the document is placed at a slight angle or if the text is 90° rotated, the software will correct this. OCR quality might vary due to ambient light, paper and print quality. Don’t fully rely on processed text alone. Check critical documents (i.e. doctor prescriptions) in Original view or Acuity Basic mode.
