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. 

1. 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.
