• Calibration
If the touchscreen isn’t working accurate, it must be calibrated.
The calibration must be done by a stylus which is meant for use with
touchscreens.
The cross shown in the diplay needs to be touched three times in a row to
calibrate the touchscreen correctly.
To make an accurate calibration, it should be touched exactly at the center
position of the cross.
ATTENTION
Don’t use any sharp object to tap the touchscreen. Don’t use a pen, but only use
your fingertips or stylus especially meant for use with touchscreens. The use of
sharp objects can cause permanent damage to the touchscreen.
