Follow these steps to initiate the Touchscreen Calibration utility for your original TAP or TAP II Controller.
Please note: The process of recalibrating your touchscreen is the same for TAP and TAP II, unless you’re using an original TAP Controller which hasn’t been updated to Software Version 5.0 or higher (in which case you can find instructions at the bottom of this page.
Turn your TAP Controller off and on again 3 times to automatically bring up the touchscreen calibration utility. When rebooting your controller, make sure you wait until the Warning Screen appears each time before restarting again AND you don’t acknowledge the warning banner.
Once the touchscreen calibration utility launches, you can tap and hold the 5 points that are indicated on screen via a yellow crosshair pattern that appears on the screen going clockwise from the upper left corner. You will move sequentially through the points from upper left to upper right to lower right to lower left to center. TAP and hold each point for approximately 5 seconds for best results.

Instructions for Original TAP Controller That Hasn’t Been Updated
If you’re using an original TAP Controller that hasn’t been updated to Software Version 5.0 or higher, we strongly recommend updating your controller software.
However, you can still recalibrate your touchscreen in the meantime. First, tap around your screen until you find an area of the screen that responds. Then, tap and hold that point for ~30 seconds to launch the touchscreen calibration utility, and follow the on-screen prompts.
