6. MAINTENANCE
To maintain reading precision above the prescribed level, keep the Scanner Window clean. To clean the Top Window,
use a soft cloth. Remove the Top Window as shown in the figure below, and wipe the Top Window softly using a dry
soft cloth. When the Top Window is badly soiled, use a cloth after moistening it with water and wringing water from
it. Then wipe the Top Window again using a dry cloth. Clean the Under Window in the same manner. Be careful not
to damage the Under Window, since it is made of acrylic and easily damaged.
