What Does The Beep Mean?
When you hear 1 beep (short high tone) it means data has been decoded
successfully. If any other beeps are heard, contact the technical person in charge
of scanning.
Maintenance
A dirty exit window may affect scanning accuracy. Clean the window with a tissue
moistened with ammonia/water. Do not spray water or other cleaning liquids
directly into the window.
