11. What about wireless phone interference with medical equipment?
Radio Frequency (RF) energy from wireless phones can interact with some electronic devices.
For this reason, the FDA helped develop a detailed test method to measure Electro Magnetic
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.

Driving

Check the laws and regulations on the use of wireless phones in the areas where you drive and always
obey them. Also, if using your phone while driving, please observe the following:
Give full attention to driving -- driving safely is your first responsibility;
Use hands-free operation, if available;
Pull off the road and park before making or answering a call if driving conditions or the law require
it.
