SAFETY

The available scientific evidence does not show that any health problems are associated with using wireless

phones. There is no proof, however, that wireless phones are absolutely safe. Wireless phones emit low levels

of radiofrequency energy (RF) in the microwave range while being used. They also emit very low levels of RF

when in the standby mode. Whereas high levels of RF can produce health effects (by heating tissue), exposure

to low level RF that does not produce heating effects causes no known adverse health effects. Many studies of

low level RF exposures have not found any biological effects. Some studies have suggested that some biological

effects may occur, but such findings have not been confirmed by additional research. In some cases, other

researchers have had difficulty in reproducing those studies, or in determining the reasons for inconsistent

results.

3 . What is FDA's role concerning the safety of wireless phones?

Under the law, FDA does not review the safety of radiation-emitting consumer products such as wireless phones

before they can be sold, as it does with new drugs or medical devices. However, the agency has authority to

take action if wireless phones are shown to emit radiofrequency energy (RF) at a level that is hazardous to the

user. In such a case, FDA could require the manufacturers of wireless phones to notify users of the health

hazard and to repair, replace or recall the phones so that the hazard no longer exists.

Although the existing scientific data do not justify FDA regulatory actions, FDA has urged the wireless phone

industry to take a number of steps, including the following:

• 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

FDA belongs to an interagency working group of the federal agencies that have responsibility for different

aspects of RF safety to ensure coordinated efforts at the federal level. The following agencies belong to this

working group:

• National Institute for Occupational Safety and Health

• Environmental Protection Agency

• Federal Communications Commission

measurements differ among phone models, depending upon available accessories and FCC requirements).

While there may be differences between the SAR levels of various phones and at various positions, they all

meet the government requirement for safe exposure.

The FCC has granted an Equipment Authorization for this model phone with all reported SAR levels evaluated

as in compliance with the FCC RF exposure guidelines. SAR information on this model phone is on file with the

FCC and can be found under the Display Grant section of http://www.fcc.gov/oet/fccid

after searching on O6Y-

PCS1400.

Additional information on Specific Absorption Rates (SAR) can be found on the Cellular Telecommunications &

Internet Association (CTIA) web-site at http://www.phonefacts.net

In the United States and Canada, the SAR limit for mobile phones used by the public is 1.6 watts/kg (W/kg)

averaged over one gram of tissue. The standard incorporates a substantial margin of safety to give

additional protection for the public and to account for any variations in measurements.

Information on Wireless Phones

1. What kinds of phones are the subject of this update?

The term “wireless phone” refers here to handheld wireless phones with built-in antennas, often called “cell,”

“mobile,” or “PCS” phones. These types of wireless phones can expose the user to measurable radiofrequency

energy (RF) because of the short distance between the phone and the user’s head. These RF exposures are

limited by Federal Communications Commission safety guidelines that were developed with the advice of 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, and thus produce RF exposures well within the FCC's

compliance limits.
