How do I reset the gyroscope in Presenter?

When the Status light flashes Green/Red for 5 seconds, this indicates that the Gyro needs calibration. Turn Presenter off and, holding the Previous Slide key, turn it back on. The Status Light will slowly flash Green/Red for 10 seconds while Presenter is calibrating, then turn solid Green for 3 seconds, indicating a successful recalibration of Presenter’s gyroscope.
