Cleaning
Exterior surfaces and scan windows exposed to spills, smudges or
debris require periodic cleaning to ensure best performance during
scanning.
Use a soft, dry cloth to clean the product. If the product is very
soiled, clean it with a soft cloth moistened with a diluted non-ag-
gressive cleaning solution or diluted ethyl alcohol.
CAUTION
Do not use abrasive or aggressive cleansing
agents or abrasive pads to clean scan windows
or plastics.
Do not spray or pour liquids directly onto the
unit.
