People who use pacemakers should avoid a physical contact with the magnetic aerial and should not handle it themselves. Keep the magnetic aerial away from the storage media such as disks, credit cards; otherwise, their data will be collapsed. The aerial should be attached so firmly that it cannot be detached in the event of a collision or sudden braking. *2 The windows with screen aerial, windscreen heating or thermally insulated screens will interfere with GPS reception, and will degrade the reliability of the Navigation System.
