Maintenance
Periodic cleaning of the scan window is the only maintenance required. A dirty window may
affect scanning ability.
• Do not allow any abrasive material to touch the scanner.
• Remove any dirt particles with a soft, lint-free cloth lightly dampened with water.
• Gently wipe the window using a lens tissue moistened with ammonia/water.
• Do not spray water or other cleaning liquids directly onto the scanner or window.
• If the scan window becomes scratched, broken or contaminated with heavy dust, replace
with a new window, which is available as an orderable accessory.
NOTE: Typical performance at 73° F (23°C) on
high quality bar codes in normal room light.
