Health and safety information
Radio Frequency (RF) Energy
This model phone meets the government’s requirements for exposure 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
Commission of the U.S. Government:
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 FCC 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 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 poser required to reach the network. In general, the
closer you are to a wireless base station antenna, the lower the power output.
The highest SAR value for the USB modem as reported to the FCC when tested for
use at body is
1.18
W/kg.
While there may be differences between the SAR levels of various 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.
SAR information on this model phone is on file with the FCC and can be found under
the Display Grant section of http://www.fcc.gov/oet/fccid after searching on
various positions, they all meet the government requirement.
