Section 14
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
