Care and Maintenance
Dust or dirt accumulating on the clear plate of the code scanning window will affect reading performance.
If you use the scanner in dusty areas, periodically check the clear plate and clean it if dusty.
- To clean the plate, first blow the dust away with an airbrush. Then wipe the plate gently with a soft item such as a cotton
swab.
- If sand or hard particles have accumulated, never rub the plate; doing so will scratch or damage it. Blow the particles away
with an airbrush or a soft brush.
■ Proper Care of the Scanner Body
Wipe any dirt from the scanner body with a dry, soft cloth.
CAUTION
- Never use substances such as benzine or alcohol, as this may cause the housing to be marred or paint to peel off.
- If excessively dirty, wipe with a soft cloth that has been soaked in soapy water (always use neutral detergent) and
wrung out thoroughly.
- Elastomer used in the housing may swell upon contact with oil or chemicals; exercise caution as the degree of
swelling will vary greatly depending on the type and amount.
