Chapter 3: Installation 3-15
Summary
If there is a Touch Screen calibration issue during or after installation,
take the following actions in the order listed:
1. Recalibrate.
2. If recalibration is unsuccessful after two attempts, then run the
Noise check to change the frequency.
3. If you are still unable to calibrate, change the touch screen glass.
4. The final step is to replace the Touch Controller Board. If this
corrects the problem, then the old glass is probably OK to reuse.
