WLAN Card User Manual Version: 0.1 2 FCC Class B Radio Frequency Interference Statement Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of 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: 1. Reorient or relocate the receiving antenna. 2. Increase the separation between the equipment and receiver. 3. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. 4. Consult the dealer or an experienced radio/television technician for help. The user should not modify or change this equipment without written approval from Fi Win, Inc. Modification could void authority to use this equipment. Notice 1: Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. Notice 2: To comply with the FCC RF exposure compliance requirements, the antenna(s) used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter . No change to the antenna or the device is permitted. Any change to the antenna or the device could result in the device exceeding the RF exposure requirements and void user’ s authority to operate the device. THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES. OPERATIONS 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 INTERFEERENCE THAT MAY CAUSE UNDESRIED OPERATION 3 Table of Contents 1.

Introduction WLAN Management Utility supports the following: 802.11b WLAN Configuration Windows 98SE / ME / 2000 (In Windows XP, we use its default WLAN Utility) PCMCIA / USB / Mini-PCI Bus Interface 2. Installation 2.1 Overview To establish your wireless network connection, the following steps should be executed. 1. Install the software using the installation CD. 2. Insert the Wireless LAN card. This product is designed for Windows 98SE, Millennium, 2000, and XP. The installation procedure for each platform is similar. Please follow the installation wizard that provided by your system install the software. 5 2.1.1 WLAN Driver/Utility Installation 1. Insert the installation CD into your CD-ROM drive. The setup program will start automatically. 6 2. Click “Next” to go to next screen. 3. Select the destination folder. To install to the default folder as shown below, click “Next” to go to the next screen. 7 4. During installation, Driver and Utility files will be copied to your system directory. 5. Select “No” and then click “Finish” to complete the installation (It is recommended to select “Yes” for Windows 98). 8 6. The shortcut will appear on your desktop. By click this icon, you can run the Utility program. You will also find a shortcut “WLAN Manager” at Start\Programs\Startup Menu as shown below: 9 7. After click the shortcut, an inverse red pyramid-like icon will appear on the bottom right of the screen. Right click that icon and select open, the WLAN Utility will pop-up on the screen. 10 2.1.2 Install the WLAN card The WLAN driver and utilities are included on the accompanying installation CD. Please follow the installation procedures in Section 2.2. (Your WLAN card will not work properly if the driver and utilities are not installed correctly). Make sure that there is an empty WLAN slot (for example PCMCIA, USB, mini-PCI) for WLAN card. Insert the WLAN Card and the installation will start automatically. When the WLAN card setup task is completed, you can run the WLAN Utility. 11 2.2 Utility Startup Configuration Details WLAN Card has its own management software. Users can control all functions provided by the application named WLAN Utility. The Utility icon will appear on the workin…

Please refer to attached test report. The authorization letter is also revised because there are two models WU28 and WU18. The difference between them is that WU18 is only 802.11 wireless LAN card but WU28 contains wireless LAN and add-in Flash Memory. They use the same schematics and layout. The user manual is revised. The RF exposure statement to declare the separation distance that end user should maintain during the operation was added. Please check. For your question 3, those frequencies you mentioned are receiving local oscillation frequencies. The levels were too low to be measured. The remarks were added on the test report. As to the test procedure in section 4.2(A), because only handheld or body worn device needs to be investigated with three axis, the procedure was corrected. Please check. regards, S. S.
