Safety
Guidelines
11.What
about
wireless
phone
interference
with
medical
equipment?
Radio
frequency
energy
(RF)
from
wireless
phones
can
interact
with
some
electronic
devices.
For
this
reason,
the
FDA
helped
develop
a
detailed
test
method
to
measure
electromagnetic
interference
(EMI)
of
implanted
cardiac
pacemakers
and
defibrillators
from
wireless
telephones.
This
test
method
is
now
part
of
a
standard
sponsored
by
the
Association
for
the
Advancement
of
Medical
instrumentation
(AAMI).
The
final
draft,
a
joint
effort
by
the
FDA,
medical
device
manufacturers,
and
many
other
groups,
was
completed
in
late
2000.
This
standard
will
allow
manufacturers
to
ensure
that
cardiac
pacemakers
and
defibrillators
are
safe
from
wireless
phone
EMI.
The
FDA
has
tested
hearing
aids
for
interference
from
handheld
wireless
phones
and
helped
develop
a
voluntary
standard
sponsored
by
the
Institute
of
Electrical
and
Electronic
Engineers
(IEEE).
This
standard
specifies
test
methods
and
performance
requirements
for
hearing
aids
and
wireless
phones
so
that
no
interference
occurs
when
a
person
uses
a
'compatible'
phone
and
a
'compatible'
hearing
aid
at
the
same
time.
This
standard
was
approved
by
the
IEEE
in
2000.
The
FDA
continues
to
monitor
the
use
of
wireless
phones
for
possible
interactions
with
other
medical
devices.
Should
harmful
interference
be
found
to
occur,
the
FDA
will
conduct
testing
to
assess
the
interference
and
work
to
resolve
the
problem.
