43<p>
44Adjusts the play radius and sensitivity for the accelerometer. Larger play radius can reduce the fluctuation of values when the Wii Remote is not moving, lower sensitivity - when the controller is moving. Movement within the play radius is not eliminated completely; however, as you approach the limit of the play radius, the amount of movement becomes extremely small. If the play radius is set to 0 and sensitivity to 1, the values obtained from the device are used without modification.
45</p>
46<p>
47The default values for play radius and sensitivity are 0 and 1, respectively. The play radius and sensitivity keep their default values on the Wii Menu as well. Set these values to their defaults in order to match Wii Menu behavior.
