MAINTENANCE

8.1

Cleaning

Clean the laser beam output window periodically for continued correct operation of 
the reader.

Dust, dirt, etc. on the window may alter the reading performance.

Repeat the operation frequently in particularly dirty environments.

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

Clean the window of the VB14A when the scanner is turned off or, at 
least, when the laser beam is deactivated.
