Ho do I calibrate the touchscreen?
Ans: The default calibration key is the “Scroll Lock” key on a computer keyboard. The default way to start a calibration is to press the scroll-lock key 6 times. The process is a four-point calibration that is zero drift and therefore should not require additional calibration. Once activating the calibration process place your finger over the tip of the cursor and hold for 7-10 seconds, then lift and repeat over the next three touch points. After the fourth and final release, the screen is calibrated.
