a radio must be in accordance with applicable regulations per airline crew instruc-
tions.
Medical Devices – Pacemakers, Defibrillators or other Implanted Medical
Devices
Persons with pacemakers, Implantable cardioverter defibrill-
ators (ICDs) or other active implantable medical devices
(AIMD) should:
• Consult with their physicians regarding the potential risk of interference from
radio frequency transmitters, such as portable radios (poorly shielded medical
devices may be more susceptible to interference).
• Turn the radio OFF immediately if there is any reason to suspect that interference
is taking place.
• Do not carry the radio in a chest pocket or near the implantation site, and carry or
use the radio on the opposite side of their body from the implantable device to
minimize the potential for interference.
Hearing Aids
Some digital wireless radios 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 RF energy. Your physician
may be able to assist you in obtaining this information.
