Electromagnetic Interference And Compatibility - Avaya 3641 Safety Information Manual

Electromagnetic Interference and Compatibility

Nearly every electronic device is susceptible to electromagnetic inter-
ference (EMI) if inadequately shielded, designed, or otherwise config-
ured for electromagnetic compatibility.
Facilities
To avoid electromagnetic interference and/or compatibility conflicts, turn off your hand-
set in any facility where posted notices instruct you to do so. Hospitals or health care
facilities may be using equipment that is sensitive to external RF energy.
Pacemakers
The Health Industry Manufacturers Association recommends that a minimum separation
of 6 inches (15 cm) be maintained between a handheld, wireless-radio product and a
pacemaker. These recommendations are consistent with the independent research by,
and recommendations of, Wireless 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 interfer-
ence is taking place.
Hearing Aids
Some digital wireless handsets may interfere with some hearing aids. The Phone
Settings option—Use Hearing Aid—is designed to improve the audio for
hearing aid users. If interference persists, 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.
