Nokia Lumia 822: Safety and Warranty
If you must conduct extended conversations by wireless phone every
day, you could place more distance between your body and the source
of the RF, since the exposure level drops off dramatically with distance.
For example, you could use a headset and carry the wireless phone
away from your body or use a wireless phone connected to a remote
antenna.
Again, the scientifi c data do not demonstrate that wireless phones are
harmful. But if you are concerned about the RF exposure from these
products, you can use measures like those described above to reduce
your RF exposure from wireless phone use.
What about children using wireless phones?
The scientifi c evidence does not show a danger to users of wireless
phones, including children and teenagers. If you want to take steps to
lower exposure to radio frequency energy (RF), the measures described
above would apply to children and teenagers using wireless phones.
Reducing the time of wireless phone use and increasing the distance
between the user and the RF source will reduce RF exposure.
Some groups sponsored by other national governments have advised
that children be discouraged from using wireless phones at all. For
example, the government in the United Kingdom distributed leafl ets
containing such a recommendation in December 2000. They noted that
no evidence exists that using a wireless phone causes brain tumors or
other ill eff ects. Their recommendation to limit wireless phone use by
children was strictly precautionary; it was not based on scientifi c evi-
dence that any health hazard exists.
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 re-
duce risks. Hands-free kits can be used with wireless phones for conve-
nience 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
Chapter 18
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 mar-
keted in the U.S. are required to meet safety requirements regardless
of whether they are used against the head or against the body. Either
confi guration 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 prod-
ucts 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 gener-
ally do not work as advertised. Unlike "handfree" 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 wire-
less phone users from radiation with making false and unsubstantiated
claims. According to FTC, these defendants lacked a reasonable basis to
substantiate their claim.
How does the FCC Audit Cell Phone RF?
After FCC grants permission for a particular cellular telephone to be
marketed, FCC will occasionally conduct "post-grant" testing to deter-
mine whether production versions of the phone are being produced
to conform with FCC regulatory requirements. The manufacturer of a
cell phone that does not meet FCC's regulatory requirements may be
required to remove the cell phone from use and to refund the purchase
price or provide a replacement phone, and may be subject to civil or
criminal penalties. In addition, if the cell phone presents a risk of injury
to the user, FDA may also take regulatory action. The most important
post-grant test, from a consumer's perspective, is testing of the RF
emissions of the phone. FCC measures the Specifi c Absorption Rate
(SAR) of the phone, following a very rigorous testing protocol. As is true
