The cursor's movement could become unstable in the following cases:

• If the Wii Remote's batteries have been replaced whilst playing a game.
• If the Wii MotionPlus accessory has been disconnected and reconnected whilst playing a game.
• If the temperature (room temperature) has changed. For example, if the Wii Remote was carried from a cold room into a warm room.

If this problem is observed during play, perform the Wii MotionPlus corrective procedure by placing the Wii Remote (with Wii MotionPlus connected) face down on a flat surface, such as a table, and waiting for a few seconds before resuming play.
