RF energy from wireless phones can interact with some
electronic devices. For this reason, 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
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. FDA
has tested hearing aids for interference from handheld
wireless phones and helped develop a voluntary
standard sponsored by the 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.
FDA continues to monitor the use of wireless phones for
possible interactions with other medical devices. Should
harmful interference be found to occur, FDA will conduct
testing to assess the interference and work to resolve
the problem.
If you must conduct extended conversations using your
Pocket PC phone every day, you could place more
distance between your body and the device, since the
exposure level drops off dramatically with distance. It is
also advisable to carry your Pocket PC phone away from
your body.
Again, the scientific data do not demonstrate that
wireless phones are harmful. But if you are concerned
about the RF exposure from these products, you can
use measures like those described above to reduce your
RF exposure from using your Pocket PC phone.

The scientific evidence does not show a danger to users
of wireless phones, including children and teenagers. If
you want to take steps to lower exposure to RF energy,
the measures described above would apply to children
and teenagers using your Pocket PC phone. Reducing
the time of using the phone function and increasing the
distance between the user and the Pocket PC phone. will
reduce RF exposure.
Some groups sponsored by other national governments
have advised that children be discouraged from using
wireless phones at all. For example, the government in
the United Kingdom distributed leaflets containing such
a recommendation in December 2000. They noted that
no evidence exists that using a wireless phone causes
brain tumors or other ill effects.Their recommendation to
limit wireless phone use by children was strictly
precautionary; it was not based on scientific evidence
that any health hazard exists.
