Touchscreen Guidelines
Use the finger or the included stylus on the display. Using a sharp or metallic object
other than your finger or stylus may cause scratches and damage the display,
thereby causing errors.
Use a soft cloth to remove dirt on the display. The touchscreen surface has a special
protective coating that prevents dirt from sticking to it. Not using a soft cloth may
cause damage to the special protective coating on the touchscreen surface.
Turn off DCU 220 power when cleaning the display. Cleaning the display with the
power on may cause improper operation.
Do not use excessive force on the display. Avoid placing objects on top of the display as
this may cause the glass to break thereby damaging the display.
Using the touchscreen during low temperature (less than 5
o
C) may cause a slower
response time, this is normal. A normal response time may be restored upon
returning to room temperature.
When there is noticeable discrepancy in the operation of the touchscreen function
(wrong location on intended operation or improper display resolution), refer to the
Windows online Help for instructions on recalibrating the touchscreen display.
