Cautions for installation
Caution Remarks
Do not install the scanner in a place
that is exposed to direct sunlight or
near a heater.
Do not install it where the temperature
and humidity are high, such as in
greenhouse, or where the
temperature is extremely low, such as
in a refrigerator. The circuits and optical components in
scanner can be damaged in an
environment where the temperature is
extremely high or low, or the humidity
is very high.
Do not install where water may be
splashed. Water entering the scanner could
cause fault.
It is recommended that you firmly
secure the scanner or cable on a table
where the scanner is set up, to
prevent it from falling off the table.
Bundle the surplus cable so that the
scanner does not fall when the cable
gets caught on something. If the scanner falls, its appearance
may be damaged or it may
malfunction.
Do not install near a device that
generates high frequencies. High frequencies could cause the
scanner to malfunction.
Set up the scanner so that no sunlight
or strong light from some lighting
device, etc. enters the scanning
window. If the sunlight or strong light from
some lighting device, etc. enters the
scanning window, reading may be
impossible.
