MAINTENANCE
REPLACEABLE PROTECTIVE OUTER WINDOW
The 7820 bar code scanner includes a replaceable protective outer window,
which protects the flat-screen window from scratches when used in harsh
scanning environments.
DAILY MAINTENANCE
Smudges and dirt on the unit's window can interfere with the unit's performance.
If the window requires cleaning, use only a mild glass cleaner containing no
ammonia. When cleaning the window, spray the cleaner onto a lint free, non-
abrasive cleaning cloth then gently wipe the window clean.
If the unit's case requires cleaning, use a mild cleaning agent that does not
contain strong oxidizing chemicals. Strong cleaning agents may discolor or
damage the unit's exterior.
