In 1999, Burger King recalled 25 million Pokemon balls from kids' meal toys to prevent choking. Four years later, Disney recalls 40,000 "Woody" dolls because children could choke on the buttons. Yamaha joins them on a much smaller scale, recalling TENORI-ONs with select serial numbers because one particular unit failed to work with batteries and actually overheated the batteries.

While this doesn't seem as disastrous and potentially traumatic as choking on Pokemon balls or parts of a Woody, Yamaha wants to ensure that their innovative new product works reliably for everyone.
