Touch screen calibration
The touch screen is already calibrated. The calibration data is stored in the
flash memory of the NQ-Series. Touch screen calibration is necessary if the
user encounters the following problems:
• Any press inside a defined object boundary does not result in the expected
action.
• An undefined area performs a task of some other defined object.
To calibrate the touch screen proceed as follows.
For accurate calibration use a stylus or wooden pencil.
• Press the centre of the touch screen for more than 2 seconds during
power-up.
• A cross is displayed at the bottom in the left corner. This cross remains on
the touch screen for approximately 4 seconds. If the centre of the cross is
not pressed at this moment, the NQ-Series resumes to normal operation.
Touch the centre of the cross with a pointed object (stylus). Keep pressing
until the NQ-Series reports
valid point
.
• The next screen is displayed with a cross at the top right corner of the
touch screen. This cross remains on the touch screen for approximately 4
seconds. If the centre of the cross is not pressed at this moment, the NQ-
Series resumes to normal operation. Touch the centre of the cross with a
pointed object (stylus). Keep pressing until the NQ-Series reports
valid
point
.
• A successfull calibration always results in a message
