Maintenance

Clean the windows periodically for continued correct operation of the reader. Dust, 
dirt, etc. on the windows may alter the reading performance.

Repeat the operation frequently in particularly dirty environments.

Use soft material and alcohol to clean the windows and avoid any abrasive 
substances.

Clean the window of the VB12 when the scanner is turned off or, at 
least, when the laser beam is deactivated.
