SAR Data

Specific Absorption Rate Data

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 
when tested for use at the ear is 1.13 W/kg, and when worn on the 
body, as described in this user guide, is 0.86 W/kg. The SAR value for 
this product in its data transmission mode (body-worn use) is 
0.81 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 
requirements for safe exposure. Please note that improvements to this 
product model could cause differences in the SAR value for later 
products; in all cases, products are designed to be within the guidelines.
