Specific Absorption Rate (SAR)
THIS USB STICK MEETS THE GOVERNMENT'S REQUIREMENTS FOR EXPOSURE TO RADIO WAVES.
Your wireless device 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 devices employs a unit of measurement known as the Specific Absorption Rate, or
SAR. The SAR limit set by the FCC is 1.6 W/kg.
* Tests for SAR are conducted 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 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 device 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 USB
Stick when tested for use when worn on the body, as described in this user guide, is 1.518 W/Kg.
(Body-worn measurements differ among device models, depending upon available accessories and
FCC requirements). While there may be differences between the SAR levels of various devices and at
various positions, they all meet the government's requirement for safe exposure. The FCC has
granted an Equipment Authorization for this USB Stick with all reported SAR levels evaluated as in
compliance with the FCC RF exposure guidelines. SAR information on this USB Stick 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 FCC ID: QISE181.Additional information on Specific Absorption Rates (SAR) can be

* In the United States and Canada, the SAR limit for mobile devices used by the public is 1.6
watts/kg (W/kg) averaged over one gram of tissue. The standard incorporates a substantial margin
