Parts of the device are magnetic. Metallic materials may be attracted to the device. Do not place credit cards or other
magnetic storage media near the device, because information stored on them may be erased.

Medical devices
Operation of radio transmitting equipment, including wireless phones, may interfere with the function of inadequately
protected medical devices. Consult a physician or the manufacturer of the medical device to determine whether they are
adequately shielded from external RF energy. Switch off your device when regulations posted instruct you to do so.
Hospitals or health care facilities may use equipment sensitive to external RF energy.
Implanted medical devices
Manufacturers of medical devices recommend a minimum separation of 15.3 centimetres (6 inches) between a wireless
device and an implanted medical device, such as a pacemaker or implanted cardioverter defibrillator, to avoid potential
interference with the medical device. Persons who have such devices should:
• Always keep the wireless device more than 15.3 centimetres (6 inches) from the medical device.
• Not carry the wireless device in a breast pocket.
• Hold the wireless device to the ear opposite the medical device.
• Turn the wireless device off if there is any reason to suspect that interference is taking place.
• Follow the manufacturer directions for the implanted medical device.
If you have any questions about using your wireless device with an implanted medical device, consult your health care
provider.
Hearing aids
Some digital wireless devices may interfere with some hearing aids.
