Installing Drivers 4 • Click Next to install a driver for the USB adapter. • Select Agree and click Next to continue the process after reviewing the license agreement. • A window will appear prompting the insertion of the Wireless Adapter. Plug the included cable into the Nfiniti AirStation Wireless USB Adapter and your PC’s USB port. Installing Drivers 5 • When the ‘Found New Hardware Wizard’ launches, click Next to run the wizard. • If the ‘Digital Signature Not Found’ page opens, click Yes. • When the Wireless USB Adapter is successfully installed, click Finish. Restart your computer if prompted. Installing Wireless Drivers  Connecting Wireless Clients to your Network Buffalo supports three different methods for connecting your wireless client device to your network. If your AP supports it, use the simple, utterly secure AOSS to connect. Install the Client Manager from your AirNavigator CD (page 7) and turn to page 10. You may also use the Client Manager software from your AirNavigator CD to configure your network manually. See page 15 for more on Client Manager. If you’re running Windows XP on your PC, you may use its built-in Zero Configuration tool to connect to your router/AP. See page 20 for more on Zero Configuration.  Client Manager can be used to survey and connect to available access points, configure WPA/WEP encryption, and create connection profiles. Note: When Client Manager is installed, Windows XP Wireless Zero Configuration is automatically disabled. Installing Client Manager Insert the AirNavigator CD into the CD- ROM drive of you computer. If the Air Navigator Setup Wizard does not launch automatically, launch it manually by clicking Start and then Run. Enter D:\ Setup.exe in the dialog box that appears. Click OK. Select Install Wireless Client Manager. Client Manager  Client Manager • Once the Client Manager Installer launches, click Next. • Press Agree to accept the license agreement and continue installation.  Client Manager • Click OK when Client Manager installation is complete. • Press Exit Setup to exit AirNavigator. • Client Manager is now installed and running. Right-click on its icon (the black antenna) to use it. 10 The AOSS button for this wireless client is in its Client Manager software. Start Client Manager by right clicking on the black antenna icon in your System Tray, or by launching the Client Manager from your Start Menu: Programs >> Buffalo >>AirStation Utility >> Client Manager. AOSS (AirStation One-Touch Secure System) is a simple, one-touch setup for connecting wireless clients to an access point while enforcing the most secure possible connection encryption type. Users no longer need to worry about choosing the proper security protocols, IP addresses, or SSID. AOSS determines the optimal connection and configures itself in seconds. If your router doesn’t support AOSS, turn to page 6 to configure your connection manually with Client Manager or Wireless Zero Config. Using AOSS 11 • From the Status Screen, select the Profiles tab. • Click the blue AOSS button on the Client Manager’s screen. The AOSS wizard will appear. • Now, press the AOSS button on the Access Point. Hold it down until the AOSS LED begins to flash. Using AOSS 12 Once AOSS is complete (about 30 seconds), the connection is archived as a profile for later use. To minimize Client Manager to the system tray, click the ‘X’ in the top right corner. Notes: AOSS will scan for an AOSS partner for about two minutes. If it times out before finding one, just press the AOSS buttons again. Output power is reduced to 25% of normal during AOSS for security reasons. If you’re having trouble making an AOSS connection, temporarily move the devices closer together. AOSS will automatically use the highest level of security available for all currently connected wireless devices. If you have trouble connecting with AOSS, temporarily disable all personal firewalls on your PC, such as ZoneAlarm or Microsoft Personal Firewall. These programs may be re- enabled after AOSS has finished. Using AOSS 1 You may use Client Manager to configure your wireless network. Client Manager consists of the Status page, the Survey page, and the Profiles page. You can access each page by clicking the corresponding button on Client Manager. In addition to these pages, several dialog boxes are also available. You can access the Edit Profile dialog box, New Profile dialog box, IP Configuration dialog box, or WEP Configuration dialog box using the Client Manager pages. You may also initiate AOSS. Status Page Click Status to open this page. By default, this page is displayed when you start Client Manager. Details of connection status are displayed. This page only displays connection information; no changes to settings are made here. This page includes the following components: • Adapter Name – Displays the part number of the wireless adaptor that is being used. Client Manager Configuration 14 Client Manager Configuration • Network Type - Displays whether network is in Ad-Hoc or Infrastructure mode. • Rate – The speed of communication between wireless devices. If the Client Manager is not connected to a remote wireless device (access point or another client), no rate will be displayed. • Channel – The channel that the two wireless clients are using for communication. If the Client Manager is not connected to a remote wireless device, no channel will be displayed. Channels 1-11 may be used. • Security – The type of encryption in use. If the Client Manager is not connected to a remote wireless device…

FCC ID: FDI-04600073-0 Report No.:RF951219L14 Operational Description This device is a 2.4GHz 54Mbps HighPower USB2.0 WirelessLAN Adapter, which operates in the 2.4GHz frequency spectrum with throughput of up to 54Mbps which OFDM technique will be applied. If the signal to noise radio is too poor which could not support 54Mbps, the 11Mbps data rate with CCK technique will be applied. The transmitter of the EUT is powered by host equipment. The antenna is Panel antenna without antenna connector. The other instruction, please have a look at the users manual.

FCC ID: FDI-04600073-0 Report No: SA951219L14 1 RF EXPOSURE REPORT REPORT NO.: SA951219L14 MODEL NO.: WLI-U2-G54HG ACCORDING: FCC Guidelines for Human Exposure IEEE C95.1 APPLICANT: Buffalo Inc. ADDRESS: 4-15, Shibata Hondori, Minami-ku, Nagoya 457-8520, Japan ISSUED BY: Advance Data Technology Corporation LAB ADDRESS: No. 47, 14th Ling, Chia Pau Tsuen, Lin Kou Hsiang 244, Taipei Hsien, Taiwan, R.O.C. TEST LOCATION: No. 19, Hwa Ya 2nd Rd., Wen Hwa Tsuen, Kwei Shan Hsiang, Taoyuan Hsien 333, Taiwan, R.O.C. FCC ID: FDI-04600073-0 Report No: SA951219L14 2 RF EXPOSURE MEASUREMENT (MOBILE DEVICE) 1. INTRODUCTION In this document, we try to prove the safety of radiation harmfulness to the human body for our product. The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. The Gain of the antenna used in this product is measured in a Fully Anechoic Chamber (FAC) calibrated for antenna measurement in ADT, and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis transmission formula is a far field assumption, the calculated result of that is an over-prediction for near field power density. We will take that as the worst case to specify the safety range. 2. RF EXPOSURE LIMIT According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in 1.1307(b) LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) FREQUENCY RANGE (MHz) ELECTRIC FIELD STRENGTH (V/m) MAGNETIC FIELD STRENGTH (A/m) POWER DENSITY (mW/cm 2 ) AVERAGE TIME (minutes) (A)LIMITS FOR OCCUPATIONAL / CONTROL EXPOSURES 300-1500 ... ...

FRIIS FORMULA Friis transmission formula : Pd = (Pout*G) / (4*pi*r 2 ) where Pd = power density in mW/cm 2 Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = distance between observation point and center of the radiator in cm If we know the maximum Gain of the antenna and the total power input to the antenna, through the calculation, we will know the MPE value at distance r. Ref.: David K. Cheng, Field and Wave Electromagnetics, Second Edition, Page 640, Eq. (11-133). 4. EUT OPERATING CONDITION The software provided by Manufacturer enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. 5. CLASSIFICATION The antenna of this product, under normal use condition, is at least 20cm away from the body of the user. Warning statement to the user for keeping at least 20cm or more separation distance with the antenna should be included in users manual. So, this device is classified as Mobile Device.
