The magnetic field of STORY has been tested safe under normal usage. At a distance of 23 cm / 9inches, the magnetic field is rated at 3 milligauss or .003 gauss. This is well below the cited sources of 10 gauss that could prevent a pace-maker from functioning properly or 5,000 gauss commonly used in MRI machines.
We are not medical professionals and do not have the specific data of the magnetic susceptibility of every medical device on the market. We recommend you contact your physician to find the rating of your specific medial device. At a safety precaution, we recommend persons with pacemakers, cochlear implants or ICD implantable cardioverter defibrillators (ICDs) to operate or be in range of further than 10 inches or 23cm from the device.
