Self-Calibration (Accupoint Mouse)
It is normal for the mouse cursor to occasionally drift for 5 to 10seconds. It will stop on its own when the calibration is complete. The Accupoint periodically performs this function on its own. This is normal! Wait until the movement stops, allow the Accupoint to run it's re-calibration process(usually 5 to 10 seconds).

NOTE: Fighting the cursor movement only prolongs the process.  Possible Hardware Problem (All Mice) If the mouse cursor drifts persistently for as long as a minute or two,and then resists your efforts to reposition it then you may have a hardware issue requiring service.  

Caution: Allowing your finger to rest on the Accupoint button may cause the mouse to begin the recalibration process.
