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.
This device 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.
FCC Caution:
• Any Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
• The antenna(s) used for this transmitter must not be co-located or operating in conjunction with
any other antenna or transmitter.
• The country code selection is for non-US model only and is not available to all US model. Per FCC
regulation, all WiFi product marketed in US must fixed to US operation channels only.
RF 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.
