Do hands-free kits for wireless phones reduce
risks from exposure to RF emissions?
Since there are no known risks from exposure to RF emissions 
from wireless phones, there is no reason to believe that hands-
free kits reduce risks. Hands-free kits can be used with wireless 
phones for convenience and comfort. These systems reduce the 
absorption of RF energy in the head because the phone, which is 
the source of the RF emissions, will not be placed against the 
head. On the other hand, if the phone is mounted against the 
waist or other part of the body during use, then that part of the 
body will absorb more RF energy. Wireless phones marketed in 
the U.S. are required to meet safety requirements regardless of 
whether they are used against the head or against the body. 
Either configuration should result in compliance with the safety 
limit.
Do wireless phone accessories that claim to shield
the head from RF radiation work?
Since there are no known risks from exposure to RF emissions 
from wireless phones, there is no reason to believe that 
accessories that claim to shield the head from those emissions 
reduce risks. Some products that claim to shield the user from 
RF absorption use special phone cases, while others involve 
nothing more than a metallic accessory attached to the phone. 
Studies have shown that these products generally do not work as 
advertised. Unlike "hand-free" kits, these so-called "shields" 
may interfere with proper operation of the phone. The phone may 
be forced to boost its power to compensate, leading to an 
increase in RF absorption. In February 2002, the Federal trade 
Commission (FTC) charged two companies that sold devices that 
claimed to protect wireless phone users from radiation with 
making false and unsubstantiated claims. 
According to FTC, these defendants lacked a reasonable basis to 
substantiate their claim.
What about wireless phone interference with
medical equipment?
Radio frequency 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
