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.

11. What about wireless phone interference with medical equipment?

Radiofrequency energy (RF) 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 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 accompanied

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.
