This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired operation.
Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio
or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
Your USB WIFI 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 USB WIFIs 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 USB WIFI 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 WIFI while operating can be well below the maximum value. This is because the USB WIFI 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 USB WIFI 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 model USB WIFI when tested for use at the ear is 0.931 W/Kg, While there may be differences between the
SAR levels of various USB WIFI and at various positions, they all meet the
government requirement for safe exposure. The FCC has granted an Equipment Authorization for this model USB WIFI with all reported SAR levels evaluated as in compliance with the FCC RF
exposure guidelines. SAR information on this model USB WIFI 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:YWTWF3CXT2CXT
Additional information on Specific Absorption Rates (SAR) can be found on the Cellular Telecommunications Industry Asso-ciation (CTIA) web-site at http://www.wow-com.com. * In the United States
and Canada, the SAR limit for mobile USB WIFI used by the public is 1.6 watts/kg (W/kg) averaged over one gram of tissue. The standard incorporates a sub-stantial margin of safety to give additional
protection for the public and to account for any variations in measurements.
