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

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,
