Device-related safety information Safety Effects of the magnetic field on devices B A A.3 Products and magnetizable data carriers (for example, storage disks, magnetic tapes, diskettes, credit cards) and precision devices (for example, watches, pagers, hearing aids) may be damaged by the magnetic field. A.3 Safety distances A.3 This table shows the effects of the magnetic fringe field on devices located in the vicinity of the magnet and the safety distances required. Observe the minimum distances to be maintained from the center of the magnet’s X, Y, and Z axes.
