Glossary ................................................................... 17 INFORMATION TO USER Federal Communication Commission Interference Statement 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 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. REGULATION INFORMATION The WLAN 11n USB Client Adapter must be installed and used in strict accordance with the manufacturer’s instructions. This device complies with the following radio frequency and safety standards. 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. (2) This device must accept any interference received, including interference that may cause undesired operation. FCC RF Radiation Exposure Statement: This Transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body. Your device contains a low power transmitter. When device is transmitted it sends out Radio Frequency (RF) signal. Use only with supplied antenna. Unauthorized antenna, modification, or attachments could damage the transmitter and may violate FCC regulations. You are cautioned that changes or modifications not expressly approved by the part responsible for compliance could void the user’s authority to operate the equipment. Europe- R&TTE Compliance Statement Hereby, the company who declares that this equipment complies with the essential requirements and other relevant provisions of DIRECTIVE 1999/5/CE OF THE EUROPEAN PARLIAMENT AND THE COUNCIL of March 9, 1999 on radio equipment and telecommunication terminal Equipment and the mutual recognition of their conformity (R&TTE). CE Declaration of Conformity For the following equipment: WLAN 11n USB Client Adapter (Product Name) WLAN 11n USB Client Adapter (Model Designation) is herewith confirmed to comply with the requirements set out in the Council (European parliament) Directive on the Approximation of the Laws of the Member States relating to Electromagnetic Compatibility of Radio and Telecom device (1999/5/EC). For the evaluation regarding this Directive, the following standards were applied: EN 300 328 V1.7.1 EN 301 489-1 V1.8.1 ; EN 301 489-17 V2.1.1 EN 60950-1:2006+A11:2009 This equipment is marked with the symbol and can be used throughout the European community. Marking by the symbol indicates that usage restrictions apply. France - 2.4GHz for Metropolitan France: In all Metropolitan départements, wireless LAN frequencies can be used under the following conditions, either for public or private use: · Indoor use: maximum power (EIRP*) of 100 mW for the entire 2400-2483.5 MHz frequency band · Outdoor use: maximum power (EIRP*) of 100 mW for the 2400-2454 MHz band and with maximum power (EIRP*) of 10 mW for the 2454-2483 MHz band Caution: Exposure to Radio Frequency Radiation. To comply with RF exposure compliance requirements, for mobile configurations, a separation distance of at least 20 cm must be maintained between the antenna of this device and all persons. This device is intended for use as check in the following European Community countries: Austria Belgium Czech Republic Cyprus Denmark Estonia France Finland Germany Greece Hungary Ireland Italy Iceland Luxemburg Latvia Lithuania Malta Norway Netherlands Portugal Poland Spain Sweden Slovakia Slovenia United Kingdom The channel identifiers, channel center frequencies, and regulatory domains of each 22-MHz-wide channel are shown in following Table.

1. MAXIMUM PERMISSIBLE EXPOSURE (MPE) 1.1 Standard Applicable According to §1.1307(b)(1) and KDB 447498 D01 General RF Exposure Guidance v05r02, system operating under the provisions of this section shall be operating in a manner that the public is not exposed to radio frequency energy level in excess limit for maximum permissible exposure. (a) Limits for Occupational / Controlled Exposure Frequency range (MHz) Electric Field Strength (E) (V/m) Magnetic Field Strength (H) (A/m) Power Density (S) (mW/cm 2 ) Averaging Times | E | 2 , | H | 2 or S (minutes) 0.3-3.0 614 1.63 (100)* 6 3.0-30 1842/f 4.89/f (900/f)* 6 30-300 61.4 0.163 1.0 6 300-1500 / / F/300 6 1500-100000 / / 5 6 (b) Limits for General Population / Uncontrolled Exposure Frequency range (MHz) Electric Field Strength (E) (V/m) Magnetic Field Strength (H) (A/m) Power Density (S) (mW/cm 2 ) Averaging Times | E | 2 , | H | 2 or S (minutes) 0.3-1.34 614 1.63 (100)* 30 1.34-30 824/f 2.19/f (180/f)* 30 30-300 27.5 0.073 0.2 30 300-1500 / / F/1500 30 1500-100000 / / 1 30 Note: f = frequency in MHz: * = Plane-wave equivalents power density 1.2 MPE Calculation Method S = (30*P*G) / (377*R 2 ) S = power density (in appropriate units, e.g., mw/cm 2 ) P = power input to the antenna (in appropriate units, e.g., mw) G = power gain of the antenna in the direction of interest relative to an isotropic radiator, the power gain factor is normally numeric gain. R = distance to the center of radiation of the antenna (in appropriate units, e.g., cm) 1.3 MPE Calculation Result Wifi: Since the maximum eirp power is used as the output power to antenna, so the Gain of the antenna can be assumed as 0dBi. Maximum peak output power: 17.89 (dBm) Maximum peak output power at antenna input terminal: 61.52(mW) Prediction distance: >20(cm) Prediction frequency: 2412 (MHz) Antenna gain (typical): 0 (dBi) Antenna gain (typical): 1 (numeric) The worst case is power density at prediction frequency at 20cm: 0.012(mw/cm 2 ) MPE limit for general population exposure at prediction frequency: 1 (mw/cm 2 ) 0.012 (mw/cm 2 ) < 1 (mw/cm 2 ) Result: Pass
