12.1.2 Touchscreen Calibration Loss
Touch screens are factory calibrated. Calibration is stored in a Flash memory. If user faces any of the
following problems:
- Any press inside defined object boundary results in three short beeps.
- Undefined area performs a task of some other defined object.
User will have to calibrate the touch screen of the unit. Steps for calibrating the touch screen for NT3S
models are as below:
1. At power ON, press the center of the NT3S screen for more than 2 to 3 seconds.
2. A cross is shown at the bottom left corner. This cross remains on the screen for
approximately 6 seconds. If center of the cross is not pressed in this time, NT3S
resumes normal operation. Touch the center of the cross with a pointed object (stylus
recommended).
3. You will get a next screen showing a cross at the top right of the screen. Again this
cross remains on the screen for approximately 6 seconds. If center of the cross is not
pressed in this time, NT3S resumes normal operation. Touch the center of the cross
with a pointed object (stylus recommended). The screen has now been calibrated.
4. Unit will be restarted. Normal function of the NT3S can now resume.
