4-Point Calibration
During calibration, a cross with a circle is gradually displayed in each corner of the monitor. For proper cali-
bration it is necessary to press and hold the center of the symbol until the blue color disappears. In this way
you ensure the setting of the exact value for pressing a point on the display.

Clear and Calibrate
With this command all currently set parameters for the touch panel are deleted and a 4-point calibration is
subsequently performed.
Linearization
This is calibration of 9 or 25 points which are uniformly arranged on the touch panel. By performing lineariza-
tion you achieve higher exactness and linearity of the touch panel. The procedure for linearization is similar
to that of 4-point calibration.
