Radio Frequency Exposure
THIS MODEL DEVICE MEETS THE GOVERNMENT’S REQUIREMENTS
FOR EXPOSURE TO RADIO WAVES.
Your wireless device is a radio transmitter and receiver. It is designed and manufactured
not to exceed the emission limits for exposure to radiofrequency (RF) energy set by the
Federal Communications Commission of the U.S. Government and also the limits set by
the Council of the European Union. 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 standards include a
substantial safety margin designed to assure the safety of all persons, regardless of age
and health.
The exposure standard for wireless mobile devices employs a unit of measurement
known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is
1.6W/kg.

Tests for SAR are conducted using standard operating positions specified
by the FCC 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 device model is available for sale to the public, it must be tested and certified
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.

In the United States and Canada, the SAR limit for mobile devices used by the
public is 1.6 watts/kg (W/kg) averaged over one gram of tissue. The EU SAR limit for
the general public is currently 2 W/kg averaged over 10 grams of body tissue. These
standards incorporate a substantial margin of safety to give additional protection for the
public and to account for any variations in measurements.
