Is it safe to use the AM11 near a pacemaker or defibrillator?
Both the machine and the remote control contain magnets, which may affect pacemakers and defibrillators. If you or someone in your household has such a device, avoid placing the remote control in a pocket or near to the device. Credit cards and electronic storage media should also be kept away from the remote control and the top of the machine. (Page 2)
