Is it safe to use the G1 if I have a pacemaker or other implanted medical device?

You should consult your doctor or the medical device manufacturer before using the G1, as the product and its charging case contain magnetic materials and components that emit radio waves, which could affect the operation of medical devices such as pacemakers, other implantable devices, hearing aids, or insulin pumps. If you notice any interference with your medical device while using the G1, turn off the electronic functionalities immediately. (Page 6)
