Radio Frequency (RF) Signals
THIS MODEL 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 the emission limits for exposure to 
radiofrequency (RF) energy set by the Federal Communications 
Commission of the U.S. Government.  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 phones 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 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 antenna, 
the lower the power output. 
Before a phone 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. The highest SAR value for 
this model phone when tested for use at the ear is 0.86 W/Kg and when 
worn on the body, as described in this users guide, is 0.68 W/Kg
.
