Tip
Do not hold the scanner directly over a barcode at 90˚. Scanning light
bounces directly back into the scanner from the barcode label is known as
specular reflection which will create a "dead zone" where decoding is
difficult. Practice a few times to find what range of angles works best.
Maintenance
Cleaning the scan window is the only maintenance required. A dirty
window may affect scanning accuracy.
Wipe the scanner window gently with a lens tissue or other material suitable
for cleaning optical material.
Do not spray water or other cleaning liquids directly onto the window.
