Health and Safety Information 125
• 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.
Children and Cell Phones
The scientific evidence does not show a danger to any users of cell phones from RF
exposure, including children and teenagers. The steps adults can take to reduce RF
exposure apply to children and teenagers as well.
