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
handsfree 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.
12.2.6 Driving safety tips
Wireless phones give people the ability to communicate
almost anywhere, anytime. But an important responsibility
accompanies those benefits, one that every wireless phone
user must uphold. When driving a car, driving is your first
responsibility.
