Appendix 109
PACEMAKERS
The Health Industry Manufacturers Association recommends that a minimum separation of six (6”) inches be
maintained between a handheld wireless phone and a pacemaker to avoid potential interference with the
pacemaker. These recommendations are consistent with the independent research by and recommendations
of Wireless Technology Research.
Never come closer than six (6) inches to a person with a heart pacemaker implant when using your device.
Doing so could result in interference with the function of the pacemaker.
Persons with pacemakers:
• Should ALWAYS keep the phone more than six inches from their pacemaker when the phone is
turned ON.
• Should not carry the phone in a breast pocket.
• Should use the ear opposite the pacemaker to minimize the potential for interference.
Note: This is not necessary if the smartphone is not held to the ear.
• If you have any reason to suspect that interference is taking place, turn the phone OFF immediately.
HEARING AIDS
Some digital wireless phones may interfere with some hearing aids. In the event of such interference, you may
want to consult your service provider, or call the customer service line to discuss alternatives.
For more regulatory information about hearing devices, see “FCC Hearing-Aid Compatibility (HAC)
Regulations for Wireless Devices”.
OTHER MEDICAL DEVICES
If you use any other personal medical device, consult the manufacturer of your device to determine if it
is adequately shielded from external RF energy. Your physician may be able to assist you in obtaining this
information.
HOSPITALS AND HEALTH CARE FACILITIES
Turn your device OFF in health care facilities when any regulations posted in these areas instruct you to do so.
Hospitals or health care facilities may be using equipment that could be sensitive to external RF energy.
ELECTRONIC DEVICES IN VEHICLES
RF signals may affect improperly installed or inadequately shielded electronic systems in motor vehicles.
Check with the manufacturer or its representative regarding your vehicle. You should also consult the
manufacturer of any equipment that has been added to your vehicle.
POSTED FACILITIES
Turn your device OFF where posted notices so require.
Turn Off Your Device Before Flying
AIRCRAFT
FCC regulations prohibit using the transmitting and phone functions of your device while in the air. In
addition, most airline regulations prohibit the on-board use of portable PCs (and all other portable electronic
devices that could potentially emit stray RF energy), particularly during take-offs and landings, to prevent any
possible interference with the reception of signals by airborne electronic navigational devices.
Turn your device OFF before boarding an aircraft. Always request and obtain prior consent and approval of an
authorized airline representative before using your device aboard an aircraft. Always follow the instructions of
