The BlackBerry smartphone 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 (FCC) of the U.S. Government, Industry Canada of the

Canadian Government (IC), and recommended by The Council of the

European Union when used as directed in the previous section. These limits

are part of comprehensive guidelines and establish permitted levels of RF

energy for the general population. The guidelines are based on standards

that were developed by independent scientific organizations through

periodic and thorough evaluation of scientific studies.

The exposure standard for wireless devices employs a unit of measurement

known as the Specific Absorption Rate, or SAR. The SAR limit set by the

FCC/IC is 1.6W/kg*. The SAR limit recommended by The Council of the

European Union is 2.0W/kg**. Tests for SAR are conducted using standard

operating positions specified by the FCC/IC with the device transmitting at

its highest certified power level in all tested frequency bands. Although the

SAR is determined at the highest certified power level, the actual SAR level

of the device while operating can be well below the maximum value. This is

because the device is designed to operate at multiple power levels so as to

use only the power required to reach the network. In general, the closer

you are to a wireless base station antenna, the lower the power output.

Before a wireless device model is available for sale to the public, it must be

tested and certified to the FCC, IC, and The Council of the European Union

that it does not exceed the limit established by the government-adopted

requirement for safe exposure under the recommendations of the

International Commission on Non-Ionizing Radiation Protection (ICNIRP).

The tests are performed in positions and locations (for example, at the ear

and worn on the body) as required by the FCC, IC, and The Council of the

European Union for each model.
