4RF EXPOSURE INFORMATION (SAR)
This device meets the government's requirements for exposure to
radio waves. This device 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 device 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
device 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 device while
operating can be well below the maximum value. This is because the
device 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. SAR compliance has been established in the host product(s)
(laptop computers), tested at 5mm separation distance and tested
