upon moving. Shortcircuit of the terminal may damage the battery and cause an 
explosion.
General Notice
• Using a damaged battery or placing a battery in your mouth or animal's mouth may 
cause serious injury including a fire or explosion.
• Do not place items containing magnetic components such as a credit card, phone 
card, bank book, or subway ticket near your phone. The magnetism of the phone 
may damage the data stored in the magnetic strip.

Health Consumer Update on Mobile Phones:
1. Do wireless phones pose a health hazard?
The available scientific evidence does not show that any health problems are associated 
with using wireless phones. There is no proof, however, that wireless...

• Support needed research into possible biological effects of RF of the type emitted 
by wireless phones;
• Design wireless phones in a way that minimizes any RF exposure to the user that is 
not necessary for device function; and
• Cooperate in providing users of wireless phones with the best possible information 
on possible effects of wireless phone use on human health.
The FDA belongs to an interagency working group of the federal agencies that have 
responsibility for different aspects of...

These RF exposures are limited by FCC safety guidelines that were developed with 
the advice of the FDA and other federal health and safety agencies. When the phone 
is located at greater distances from the user, the exposure to RF is drastically lower 
because a person's RF exposure decreases rapidly with increasing distance from 
the source. The so-called “cordless phones,”which have a base unit connected to 
the telephone wiring in a house, typically operate at far lower power levels,...

5. What research is needed to decide whether RF exposure from wireless 
phones poses a health risk?
A combination of laboratory studies and epidemiological studies of people actually 
using wireless phones would provide some of the data that are needed. Lifetime animal 
exposure studies could be completed in a few years. However, very large numbers of 
animals would be needed to provide reliable proof of a cancer promoting effect if one 
exists. Epidemiological studies can provide data that is...

research will include both laboratory studies and studies of wireless phone users. The 
CRADA will also include a broad assessment of additional research needs in the context 
of the latest research developments around the world.
7. How can I find out how much Radio Frequency energy exposure I can get by 
using my wireless phone?
All phones sold in the United States must comply with Federal Communications 
Commission (FCC) guidelines that limit Radio Frequency (RF) energy exposures. The 
FCC...

of measurements made at different laboratories on the same phone. SAR is the 
measurement of the amount of energy absorbed in tissue, either by the whole body 
or a small part of the body. It is measured in watts/kg (or milliwatts/g) of matter. This 
measurement is used to determine whether a wireless phone complies with safety 
guidelines.
9. What steps can I take to reduce my exposure to Radio Frequency energy from 
my wireless phone?
If there is a risk from these products — and at this point...

that no evidence exists that using a wireless phone causes brain tumors or other ill 
effects. Their recommendation to limit wireless phone use by children was strictly 
precautionary; it was not based on scientific evidence that any health hazard exists.
11. What about wireless phone interference with medical equipment?
Radio Frequency (RF) energy from wireless phones can interact with some electronic 
devices. For this reason, the FDA helped develop a detailed test method to measure 
Electro...

  Driving
Check the laws and regulations on the use of wireless phones in the areas where you 
drive and always obey them. Also, if using your phone while driving, please observe the 
following:
• Give full attention to driving – driving safely is your first responsibility;
• Use hands-free operation, if available;
• Pull off the road and park before making or answering a call if driving conditions or 
the law require it.

4  Suspend conversations during hazardous driving conditions or situations. Let the 
person you are speaking with know you are driving; if necessary, suspend the call 
in heavy traffi c or hazardous weather conditions. Rain, sleet, snow, and ice can 
be hazardous, but so is heavy traffi c. As a driver, your fi rst responsibility is to pay 
attention to the road.
