Wii game play with the Wii Remote can involve rapid or vigorous motion. Please use the wrist strap to prevent losing your grip on the Wii Remote and causing damage to the Wii Remote and surrounding objects, or injury to other people.
Give yourself plenty of room! You will probably move around while using the Wii Remote, so be careful that all areas that you might move into are clear. Make sure that furniture, objects and people are out of the play area so you don’t accidentally bump into them while playing. Also, as indicated in the Wii Operations Manual, it is recommended to stay at least 1 metre (3 feet) from the television.
