• Use speaker mode or a headset to place more distance
between your head and the cell phone.
Hands-Free Kits
Hands-free kits may include audio or Bluetooth
®
headsets
and various types of body-worn accessories such as
belt-clips and holsters. Combinations of these can be
used to reduce RF energy absorption from cell phones.
Headsets can substantially reduce exposure because the
phone is held away from the head in the user's hand or in
approved body-worn accessories. Cell phones marketed
in the U.S. are required to meet RF exposure compliance
requirements when used against the head and against the
body.
Because there are no known risks from exposure to RF
emissions from cell phones, there is no reason to believe
that hands-free kits reduce risks. Hands-free kits can be
used for convenience and comfort. They are also required
by law in many states if you want to use your phone while
driving.
Cell Phone Accessories that Claim to Shield the
Head from RF Radiation
Because there are no known risks from exposure to RF
emissions from cell phones, there is no reason to believe
that accessories which 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 “hands-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.
