SAR Data
This model wireless phone meets the 
government’s requirements for exposure to radio 
waves.
Your wireless phone is a radio transmitter and receiver. It is 
designed and manufactured not to exceed limits for exposure to 
radio frequency (RF) energy set by the Federal Communications 
Commission (FCC) of the U.S. Government and by the Canadian 
regulatory authorities. 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 or health.
The exposure standard for wireless mobile phones employs a unit 
of measurement known as the Specific Absorption Rate, or SAR. 
The SAR limit set by the FCC and by the Canadian regulatory 
authorities is 1.6 W/kg.

 Tests for SAR are conducted using 
standard operating positions accepted by the FCC and by Industry 
Canada with the phone 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 phone while operating can be well below the 
maximum value. This is because the phone 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, the lower the power output.
Before a phone model is available for sale to the public in the U.S. 
and Canada, it must be tested and certified to the FCC and Industry 
Canada that it does not exceed the limit established by each 
government for safe exposure. The tests are performed in 
positions and locations (e.g., at the ear and worn on the body) 
reported to the FCC and available for review by Industry Canada. 
The highest SAR value for this model phone (850/1800/1900) 
when tested for use at the ear is 1.40 W/kg, and when worn on the 
body, as described in this user guide, is 1.03 W/kg. (Body-worn 
measurements differ among phone models, depending upon 
available accessories and regulatory requirements).

 The highest 
SAR value for this model phone (900/1800/1900) when tested for 
use at the ear is 0.54 W/kg, and when worn on the body, as 
described in this user guide, is 0.27 W/kg. (Body-worn 
measurements differ among phone models, depending upon 
available accessories and regulatory requirements).

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