Apple Inc said there might be a possible defect in its iPod nano battery cells. The defect is related to fire incidents when the media player overheats.
More recently, Japan’s trade ministry said iPod nanos with known overheating incidents were sold in Japan between September 2005 and September 2006.
No one was injured in the three reported fire incidents.
Apple was not available for comment.
However, Apple has reported two other incidents where consumers had suffered minor burns after their media player overheated.
Officials have assigned a product safety group to inspect the incidents in cooperation with Apple.
“We are not in the position to speculate on the outcome of the investigation. But after several incidents like these, it would be appropriate for Apple to take some measures to raise the public’s awareness,” the trade ministry said.
iPod Nano has been updated twice since its launch. The gadget is the highest-selling media player in history.
