Preventing damage to health and accidents

adapters. Always remove the earphones
slowly and carefully from your ears.

cardiac pacemakers, implanted defibril-
lators (ICDs) and other implants. Always
maintain a distance of at least 3.94"/10 cm
between the product component containing
the magnet and the cardiac pacemaker, im-
planted defibrillator, or other implant.

aging parts out of reach of children and
