Motorola MC9190 Screen Calibration
If the mouse pointer (stylus) does not match the screen location on your Motorola MC9190, then you need to recalibrate the screen. Press the Blue key (it is just under the power button) and then the ESC key. This will bring up the recalibration screen. Follow the prompts and be sure to press ENTER at the end.
Note: you can press the ESC button at any time to skip the screen calibration process.
