MEDICAL DEVICES Operation of radio transmitting equipment, including wireless phones, may interfere with inadequately shielded medical devices' function. Consult a physician or the medical device's manufacturer to determine if it is adequately shielded from external radio energy. IMPLANTED MEDICAL DEVICES To avoid potential interference, manufacturers of implanted medical devices recommend a minimum separation of 15.3 centimeters (6 inches) between a wireless device and the medical device. Persons who have such devices should: • Always keep the wireless device more than 15.3 centimeters (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. • Switch 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. © 2020 HMD Global Oy.
