Health and safety information
Radio Frequency (RF) Energy
This USB MODEM
meets the government’s requirements for exposure to radio waves.
This USB MODEM 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 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 accepted by the FCC with the USB MODEM 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
USB MODEM while operating can be well below the maximum value. This is because the USB MODEM 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.
