What safety warnings apply to the BITE magnet accessory on the Phantom 2?

The included mounting accessory contains a Neodymium magnet that could affect the functioning of pacemakers and implanted heart defibrillators — users of such devices should keep sufficient distance from the magnet. The magnet may also permanently lose part of its adhesive force if exposed to temperatures above 175°F (80°C). Additionally, the strong magnetic field can damage TVs, laptops, computer hard drives, credit and ATM cards, mechanical watches, hearing aids, and speakers. (Page 9)
