This model phone meets the governmentÕs 
requirements for exposure to radio waves. 
Your wireless phone is a radio transmitter and receiver. It is 
designed and manufactured not to exceed the emission limits for 
exposure to radio frequency (RF) energy set by the Federal 
Communications Commission of the U.S. Government. These 
limits are part of comprehensive guidelines and establish 
permitted levels of RF energy for the general population. The 
guidelines are based on...

92Before a phone model is available for sale to the public, it must 
be tested and certiÞed to the FCC that it does not exceed the 
limit established by the government-adopted requirement for 
safe exposure. The tests are performed in positions and locations 
(e.g., at the ear and worn on the body) as required by the FCC 
for each model. The highest SAR value for this model phone 
when tested for use at the ear is 1.55 W/kg
2, and when worn on 
the body, as described in this user guide, is 1.41 W/kg.2...

FDA has been receiving inquiries about the safety of mobile 
phones, including cellular phones and PCS phones. The following 
summarizes what is knownÑand what remains unknownÑ
about whether these products can pose a hazard to health, and 
what can be done to minimize any potential risk. This 
information may be used to respond to questions.

What kinds of phones are in question?
Questions have been raised about hand-held mobile phones, the 
kind that have a built-in antenna that is positioned close to the 
users head during normal telephone conversation. These types 
of mobile phones are of concern because of the short distance 
between the phones antennaÑthe primary source of the RFÑ
and the persons head. The exposure to RF from mobile phones 
in which the antenna is located at greater distances from the 
user (on the outside of a car,...

95 First, it is uncertain how to apply the results obtained in rats and 
mice to humans. Second, many of the studies that showed 
increased tumor development used animals that had already 
been treated with cancer-causing chemicals, and other studies 
exposed the animals to the RF virtually continuouslyÑup to 22 
hours per day.
For the past Þve years in the United States, the mobile phone 
industry has supported research into the safety of mobile 
phones. This research has resulted in two Þndings in...

accuracy and repeatability of these results.

2Researchers conducted a large battery of laboratory tests to 
assess the effects of exposure to mobile phone RF on 
genetic material. These included tests for several kinds of 
abnormalities, including mutations, chromosomal 
aberrations, DNA strand breaks, and structural changes in 
the genetic material of blood cells called lymphocytes. None 
of the tests showed any effect of the RF except for the...

97 performed cognitive function tests. There were no changes 
in the subjects ability to recall words, numbers, or pictures, 
or in their spatial memory, but they were able to make 
choices more quickly in one visual test when they were 
exposed to simulated mobile phone signals. This was the 
only change noted among more than 20 variables 
compared.

98each year. At that rate, assuming 80 million users of mobile 
phones (a number increasing at a rate of about 1 million per 
month), about 4800 cases of brain cancer would be expected 
each year among those 80 million people, whether or not they 
used their phones. Thus it is not possible to tell whether any 
individuals cancer arose because of the phone, or whether it 
would have happened anyway. A key question is whether the 
risk of getting a particular form of cancer is greater among 
people who use...

99 industry to take a number of steps to assure public safety. The 
agency has recommended that the industry:
¥ support needed research into possible biological effects of 
RF of the type emitted by mobile phones
¥ design mobile phones in a way that minimizes any RF 
exposure to the user that is not necessary for device 
function
¥ cooperate in providing mobile phone users with the best 
possible information on what is known about possible 
effects of mobile phone use on human health
At the same time,...

100factor in how much exposure a person receives. Those persons 
who spend long periods of time on their hand-held mobile 
phones could consider holding lengthy conversations on 
conventional phones and reserving the hand-held models for 
shorter conversations or for situations when other types of 
phones are not available.
People who must conduct extended conversations in their cars 
every day could switch to a type of mobile phone that places 
more distance between their bodies and the source of the...
