these minor maintenance tasks:

• Clean the CN50 screen.
Clean the scanner window and CN50 screen as often as needed for the
environment in which you are using the computer. To clean the
CN50, use a solution of ammonia and water.

the excess. Wipe off the scanner window and screen. Do not allow

unit will void the warranty and may cause damage to the internal
components.
