Radio Frequency (RF) Energy
Thi s m odel phone meets the government’s r equirements for expo sure to radio waves. This phone is designed and manufactured not to exceed the emission limits for exposure to radio frequency (RF) energy set by the Federal Communications Comm issio n of the U.S. Gove rnment: The exposure standard for wireless USB modem employs a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit set by the FC C is
1.6W/kg. *Tests for SAR are conducted using standard operating positions accepted 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 certi fied 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 level s so as to use on ly the poser requ ired to rea ch the networ k. In general , the closer you are to a wireless base station antenna, the lower the power output. The hi gh est SA R val u e for the USB modem as reported to the FCC when tested for use at body is 1.18 W/kg. Whil e there may b e diff erences b etween the S AR level s of vari ous phones and at various positions, they all meet the government requirement. The FCC has granted an Equipment Authorization for this model phone with all reported SAR levels evaluated as in compliance with the FCC RF exposure guidelines.
