Quick Installation Guide
FCC 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.
To assure continued compliance, any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. (Example - use only shielded interface cables when connecting to computer or peripheral devices).
This device has been tested and meets the FCC RF exposure guidelines. The maximum SAR value reported is 0.88w/kg
Channel
The Wireless Channel sets the radio frequency used for communication.
Access Points use a fixed Channel. You can select the Channel used. This allows you to choose a Channel which provides the least interference and best performance. In the USA and Canada, 11 channel are available. If using multiple Access Points, it is better if adjacent Access Points use different Channels to reduce interference.
In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an Access Point. If more than one Access Point can be used, the one with the strongest signal is used. (This can only happen within an ESS.)
If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the same Channel. However, most Wireless stations will still scan all Channels to see if there is an existing "Ad-hoc" group they can join.
About This Guide
This Quick Installation Guide describes the basic installation of the CB801A/AS. It covers the following topics:
n Before You Begin n Installing the Wireless Configuration Util ity n Installing the PC Card Driver
For complete instructions on using the PC Card, see the CB801A/AS Wireless 54Mbps 11g PC Card User Guide on the Installation CD.
Before You Begin
Before installing the PC Card, perform the following checks:
n Check the package contents n Verify that your computer meets the system requirements
Check the Package Contents
Before starting with the installation, verify that your PC Card package includes the following items:

You can install the PC Card on any computer running Microsoft® Windows® XP, Windows 2000, Windows 98 SE, or Windows Me. Your computer must also have, at least, the following:
n PCMCIA card slot n 400 MHz processor or higher n 128 MB of RAM n CD-ROM drive
Installing the Wireless Configuration Utility
Your Wireless PC Card includes a configuration utility that you can use to manage your PC Card.
Windows XP Service Pack 2 has a built-in service called Wireless Zero Configuration (WZC) that can also be used to manage your wireless connections. If you intend to use WZC to manage your PC Card, you do not have to install the configuration utility.
To install the wireless configuration utility:
1. With the computer on and Windows running, insert the Installation CD into the CD-ROM drive. The CB801A/AS Wireless Utility Installation wizard automatically starts. If the installation wizard does not start automatically, click Start > Run, and then type d:\setup.exe (where d: is the drive letter assigned to your CD-ROM drive).
2. Follow the instructions on the wizard to install the wireless configuration utility. If a message appears, informing you that the driver has not passed the Windows Logo testing, click Continue Anyway to complete the installation.
3. When the message “InstallShield Wizard Complete” appears, click Finish to complete installing the wireless configuration utility.
Installing the PC Card Driver
1. Insert the PC Card into your computer’s PCMCIA card slot.
2. Click Install the software automatically (Recommended), and then click Next.
n If a message appears, informing you that the driver has not passed
the Windows Logo testing, click Continue Anyway to continue with the installation.
n If the wizard does not automatically detect the driver for the PC
Card and prompts its the location, click Browse, and then select the appropriate Windows driver on the Installation CD. The PC Card drivers on in the \Driver folder on the CB801A/AS Installation CD. Click Open, and then OK to continue.
Windows installs the driver for the PC Card.
3. When the message “Completing the Found New Hardware Wizard” appears, click Finish to complete the driver installation.
