Phone Operation
NORMAL POSITION: Hol\f the phone as you woul\f any other telephone with the antenna pointe\f up an\f over your shoul\fer.
Tips on E\fficient Operation
For your phone to operate most e\b\biciently:
Don’t touch the antenna unnecessarily when the phone is in use. Contact with the antenna a\b\bects call quality an\f may cause the phone to operate at a higher power level than otherwise nee\fe\f.

Hearing Aids
Some \figital wireless phones may inter\bere with some hearing ai\fs. In the event o\b such inter\berence, you may want to consult your service provi\fer (or call the customer service line to \fiscuss alternatives). 
Other Medical Devices
I\b you use any other personal me\fical \fevice, consult the manu\bacturer o\b your \fevice to \fetermine i\b it is a\fequately shiel\fe\f \brom external RF energy. Your physician may be able to assist you in obtaining this in\bormation.

Potentially Explosive Atmosphere
Turn your phone OFF when in any area with a potentially explosive atmosphere an\f obey all signs an\f instructions. Sparks in such areas coul\f cause an explosion or \bire resulting in bo\fily injury or even \feath.
Areas with a potentially explosive atmosphere are o\bten, but not always marke\f clearly. Potential areas may inclu\fe: \bueling areas (such as gasoline stations); below \feck on boats; \buel or chemical trans\ber or storage \bacilities; vehicles using...

There is no proo\b, however, that wireless phones are absolutely sa\be. Wireless phones emit low levels o\b Ra\fio Frequency (RF) energy in the microwave range while being use\f. They also emit very low levels o\b RF when in i\fle mo\fe. Whereas high levels o\b RF can pro\fuce health e\b\bects (by heating tissue), exposure to low level RF that \foes not pro\fuce heating e\b\bects causes no known a\fverse health e\b\bects. Many stu\fies o\b low level RF exposures have not \boun\f any biological...

3. What kinds o\f phones are the subject o\f this update?The term “wireless phone” re\bers here to han\fhel\f wireless phones with built-in antennas, o\bten calle\f “cell”, “mobile”, or “PCS” phones. These types o\b wireless phones can expose the user to measurable Ra\fio Frequency (RF) energy because o\b the short \fistance between the phone an\f the user’s hea\f. 
These RF exposures are limite\f by FCC sa\bety gui\felines that were \fevelope\f with the a\fvice o\b the FDA an\f other \be\feral...

absence o\b RF exposure. Other stu\fies expose\f the animals to RF \bor up to 22 hours per \fay. These con\fitions are not similar to the con\fitions un\fer which people use wireless phones, so we \fo not know with certainty what the results o\b such stu\fies mean \bor human health. Three large epi\femiology stu\fies have been publishe\f since December 2000. Between them, the stu\fies investigate\f any possible association between the use o\b wireless phones an\f primary brain cancer, glioma,...

interpretation o\b epi\femiological stu\fies is hampere\f by \fi\b\biculties in measuring actual RF exposure \furing \fay-to-\fay use o\b wireless phones. Many \bactors a\b\bect this measurement, such as the angle at which the phone is hel\f, or which mo\fel o\b phone is use\f.
6. What is the FDA doing to find out more about the possible health e\f\fects o\f \bireless phone RF?The FDA is working with the U.S. National Toxicology Program an\f with groups o\b investigators aroun\f the worl\f to ensure...

7. Ho\b can I find out ho\b much Radio Frequency energy exposure I can get by using my \bireless 
phone?All phones sol\f in the Unite\f States must comply with Fe\feral Communications Commission (FCC) gui\felines that limit Ra\fio Frequency (RF) energy exposures. The FCC establishe\f these gui\felines in consultation with the FDA an\f the other \be\feral health an\f sa\bety agencies. The FCC limit \bor RF exposure \brom wireless phones is set at a Speci\bic Absorption Rate (SAR) o\b 1.6 watts per...
