Handset Administration
Electromagnetic Interference and Compatibility
Facilities
To avoid electromagnetic interference and/or compatibility conflicts, turn
off your handset in any facility where posted notices instruct you to do so.
Hospitals or health care facilities may be using equipment that is sensi-
tive to external RF energy.
Pacemakers
The Health Industry Manufacturers Association recommends that a mini-
mum separation of 6 inches (15 cm) be maintained between a handheld,
wireless-radio product and a pacemaker. These recommendations are con-
sistent with the independent research by, and recommendations of, Wire-
less Technology Research. Persons with pacemakers should:
• ALWAYS keep the handset more than 6 inches (15 cm) from their
pacemaker when the handset is turned ON.
• Not carry the handset in a breast pocket.
• Use the ear opposite the pacemaker to minimize the potential for
interference.
• Turn the handset OFF immediately if you have any reason to suspect
that interference is taking place.
Hearing Aids
Some digital wireless handsets may interfere with some hearing aids. In
the event of such interference, you may want to consult your hearing-aid
manufacturer to discuss alternatives.
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.
Nearly every electronic device is susceptible to electro-
magnetic interference (EMI) if inadequately shielded,
designed, or otherwise configured for electromagnetic
compatibility.
