Requirements for Installation  
To install and use the Wireless Broadband Router you need a computer equipped with an Ethernet  
port (such as an Ethernet NIC) and a web browser.  
WLAN Ethernet Adapter  
Any computer that uses the Wireless Broadband Router must be able to connect to it through the  
Wireless Ethernet (WLAN) on the Wireless Broadband Router. This connection is a Wireless Ethernet  
(WLAN or WiFi) connection and therefore requires that your computer be equipped with a Wireless  
Ethernet Adapter as well. Many notebook computers are now sold with a Wireless Ethernet Adapter  
already installed. There is also a Wired Ethernet port that is used to connect the WLAN adapter to  
your wired network. This port can be used to configure the Wireless Broadband Router. Most fully  
assembled desktop computers come with an Ethernet NIC adapter as standard equipment. If your  
computer does not have an Ethernet port, you must install an Ethernet NIC adapter before you can  
configure the Wireless Broadband Router. If you must install an adapter, follow the installation  
instructions that come with the Ethernet NIC adapter.  
Operating System  
The Wireless Broadband Router uses an HTML-based web interface for setup and management. The  
web configuration manager may be accessed using any operating system capable of running web  
browser software.  
Web Browser  
Any common web browser can be used to configure the Wireless Broadband Router using the web  
configuration management software. The program is designed to work best with more recently  
released browsers such as Microsoft Internet Explorer® version 6.0, Netscape Navigator® version  
6.2.3, or later versions. The web browser must have JavaScript enabled. JavaScript is enabled by  
default on many browsers. Make sure JavaScript has not been disabled by other software (such as  
virus protection or web user security packages) that may be running on your computer.

Wireless LAN  
A Wireless LAN is a cellular computer network that transmits data using radio signals instead of  
cables. Wireless LAN technology is commonly used for home, small office and large corporate  
networks. Wireless LAN devices have a high degree of mobility and flexibility that allow network to  
be quickly set up or dismantled and allow them to roam freely throughout the network.  
The IEEE 802.11n Wireless LAN standard is an improvement on the IEEE 802.11g standard. The  
802.11n embedded Wireless LAN access point is fully compatible with legacy IEEE 802.11b and IEEE  
802.11g devices.  
Some basic understanding of wireless technology and terminology is useful when you are setting up  
the Wireless Broadband Router or any wireless access point. If you are not familiar with wireless  
networks please take a few minutes to learn the basics.  
For home users who will not incorporate a RADIUS server in their network, the security for the  
Conceptronic C300BRS4A, used in conjunction with other WPA-compatible 802.11 products, will still  
be much stronger than ever before. Utilizing the Pre-Shared Key mode of WPA, the Wireless  
Broadband Router will obtain a new security key every time it connects to the 802.11 network. You  
only need to input your encryption information once in the configuration menu. No longer will you  
have to manually input a new WEP key frequently to ensure security. With the Wireless Broadband  
Router, you will automatically receive a new key every time you connect, vastly increasing the  
safety of your communication.  
The Wireless Broadband Router is an ideal solution for quickly creating and extending a wireless  
local area network (WLAN) in offices or other workplaces, trade shows and special events. The  
802.11n standard is backwards compatible with 802.11b and 802.11g devices.  
The Wireless Broadband Router has the newest, strongest, most advanced security features  
available today. When used with other 802.11n WPA (WiFi Protected Access) compatible products in  
a network with a RADIUS server, the security features include:  
WPA: WiFi Protected Access, which authorizes and identifies users, based on a secret key that  
change automatically at regular intervals. WPA uses TKIP (Temporal Key Integrity Protocol) to  
change the temporal key every 10,000 packets (a packet is a kind of message transmitted over a  
network.) This insures much greater security than the standard WEP security. (By contrast, the  
previous WEP encryption implementation required the keys to be changed manually.)

Radio Transmission  
Wireless LAN devices use electromagnetic waves within a broad, unlicensed range of the radio  
spectrum to transmit and receive radio signals. When a wireless access point is present, it becomes  
a base station for the Wireless LAN nodes in its broadcast range. Wireless LAN nodes transmit digital  
data using FM (frequency modulation) radio signals. Wireless LAN devices generate a carrier wave  
and modulate this signal using various techniques. In this way, digital data can then be  
superimposed onto the carrier signal. This radio signal carries data to Wireless LAN devices within  
range of the transmitting device. The antennae of Wireless LAN devices listen for and receive the  
signal.  
Range  
Range should not be a problem in most homes or small offices. If you experience low or no signal  
strength in some areas, consider positioning the device in a location between the Wireless LAN  
devices maintaining a roughly equal straight-line distance to all devices that need to access the  
Wireless Broadband Router through the wireless interface. Adding more 802.11n access points to  
rooms where the signal is weak can improve signal strength.  
SSID  
Wireless networks use an SSID (Service Set Identifier) to allow wireless devices to roam within the  
range of the network. Wireless devices that wish to communicate with each other must use the  
same SSID. Several Wireless Broadband Routers or access points can be set up using the same SSID so  
that wireless stations can move from one location to another without losing connection to the  
wireless network.  
The Wireless Broadband Router operates in Infrastructure mode. It controls network access on the  
wireless interface in its broadcast area. It will allow access to the wireless network to devices using  
the correct SSID after a negotiation process takes place. The Conceptronic C300BRS4A broadcasts its  
SSID so that any wireless station in range can learn the SSID and ask permission to associate with it.  
Many wireless adapters are able to survey or scan the wireless environment for access points. An  
access point in Infrastructure mode allows wireless devices to survey that network and select an  
access point with which to associate.

802.11n Wireless Broadband Router  
Hardware Installation  
Place the Wireless Broadband Router in a location where it can be easily connected to the wired  
interface (Ethernet link to a broadband modem, for example) as well as function effectively as a  
Wireless LAN access point. Make sure the Wireless Broadband Router is near a suitable power  
source.  
Connect the bundled power supply to the power connection on the back of the C300BRS4A and to a  
free wall power outlet. The Power LED of the C300BRS4A will turn on.  
Wireless LAN Performance and Environment  
Many environmental factors can affect the effective wireless function of the Wireless Broadband  
Router. If this is your first time setting up a wireless network device, read and consider the points  
listed below.  
The Wireless Broadband Router can be placed on a shelf or desktop, ideally you should be able to  
see the LED indicators on the front if you need to view them for troubleshooting.  
The Wireless Broadband Router lets you access your network within range of the device. However,  
walls, ceilings, or other objects that the wireless signals must pass through can limit signal range.  
Typical ranges vary depending on the types of materials and background RF noise in your home or  
business. For maximum range and signal strength, use these basic guidelines:  
1. Keep the number of walls and ceilings to a minimum:  
The signal emitted from Wireless LAN devices can penetrate through ceilings and walls.  
However, each wall or ceiling can reduce the range Wireless LAN devices from 1 to 30M.  
Position your wireless devices so that the number of walls or ceilings obstructing the signal  
path is minimized.  
2. Consider the direct line between access points and workstations:  
A wall that is 0.5 meters thick, at a 45-degree angle appears to be almost 1 meter thick. At a  
2-degree angle, it is over 14 meters thick. Be careful to position access points and client  
adapters so the signal can travel straight through (90º angle) a wall or ceiling for better  
reception.  
3. Building Materials make a difference:  
Buildings constructed using metal framing or doors can reduce effective range of the device. If  
possible, position wireless devices so that their signal can pass through drywall or open  
doorways, avoid positioning them so that their signal must pass through metallic materials.  
Poured concrete walls are reinforced with steel while cinderblock walls may have little or no  
structural steel.  
4. Keep the Wireless Broadband Router away (at least 1-2 meters) from electrical devices:  
Position wireless devices away from electrical devices that generate RF noise such as micro-  
wave ovens, monitors, electric motors, etc.

5. Position antenna for best reception:  
Adjust the antenna position to see if the signal strength improves. Some adapters or access  
points allow the user to judge the strength of the signal. Use this method, if available, to test  
signal strength.  
WAN Connection  
Use a LAN Cable to connect the C300BRS4A to your Broadband Gateway (Cable Modem, DSL Modem,  
Fiber Gateway, etc.)  
The WAN LED on the front side of the C300BRS4A will turn on.  
Note: If the WAN LED on the front side does not turn on, make sure that:  
- The C300BRS4A is powered (the Power LED should burn).  
- The Broadband Gateway is turned on.  
- The LAN cable between both devices is connected correctly.  
LAN / Wireless LAN Connection  
For LAN Cable Users:  
Connect the LAN Cable to 1 of the 4 LAN ports on the back panel of the C300BRS4A and to the  
Network Card in your computer.  
The LAN LED of the used LAN port will turn on, indicating that the computer is connected. (Your  
LAN Connection must be enabled and your computer turned ON).  
For Wireless Users:  
You can connect wireless to the C300BRS4A in 2 different ways:  
-
-
Manually, without encryption.  
Automatically with the WPS feature, with encryption.  
If you have 1 or more clients which do not support WPS, it is advised to manually connect to the  
C300BRS4A, or secure the wireless connection manually before you connect to the C300BRS4A.  
You can secure your connection manually with the configuration wizard, explained in the chapter

WPS Security  
The Conceptronic C300BRS4A supports WPS (Wi-Fi Protected Setup). WPS is a standard for easy and  
secure establishment of a wireless network. With WPS you can setup and protect your wireless  
network in just a few easy steps.  
Note: To use WPS with the C300BRS4A, you need to have Wireless Clients which supports WPS. If  
you have 1 or more Wireless Clients without WPS support, it is advised to secure your  
network manually using the Setup Wizard.  
Note: For more (technical) information about WPS, you can visit the following website:  
The C300BRS4A supports 2 ways to activate and establish a WPS connection:  
-
-
Push Button technology  
Pin Code technology  
WPS – Push Button technology  
The WPS Push Button technology requires a (virtual) button on your Wireless Client to establish a  
connection between the C300BRS4A and your Wireless Client.  
Some Wireless Clients work with a real button to activate the WPS Push Button technology; some  
Wireless Clients use a software-based virtual button.  
Follow the steps below to activate and establish a WPS connection with the Push Button technology:  
A. Press the WPS Button at the front of the C300BRS4A until the WPS LED blinks.  
B. Press the WPS Button at your Wireless Client. This can be a hardware button or a virtual  
button in the software of your Wireless Client.  
The C300BRS4A will activate WPA security over your wireless network and accepts the wireless  
connection of your Wireless Client.  
Note: The C300BRS4A will keep the WPS authentication active for 120 seconds. During this process,  
the WPS LED will blink. If there is no connection in these 120 seconds, the LED will turn off  
and the WPS authentication process is stopped.  
If the WPS feature is not used earlier, the wireless network will still be unencrypted.  
If the authentication of the Wireless Client is succeeded, the WPS LED will burn steady blue for 5  
minutes. After these 5 minutes, the LED will turn off.  
Your Wireless Client is now connected to the C300BRS4A and your network is secured with WPA  
Encryption.  
You can add more Wireless WPS Clients without loosing the connection to previous Wireless WPS  
Clients.  
If you want to add more Wireless WPS clients, repeat step A & B.  
Note: The WPA Key generated by the C300BRS4A is random.

Static IP Address  
When the Router is configured to use Static IP Address assignment for the WAN connection, you  
must manually assign a global IP Address, Subnet Mask and Gateway IP Address used for the WAN  
connection. Follow the instruction below to configure the Router to use Static IP Address assignment  
for the WAN connection.  
To configure a Static IP Address connection, perform the steps listed below. Some of the settings do  
not need to be changed the first time the device is set up, but can be changed later if you choose.

available) Secondary DNS Address as instructed by your ISP. These are the global IP settings  
for the WAN interface. This is the “visible” IP address of your account. Your ISP should have  
provided these IP settings to you.  
3. Some ISPs record the unique MAC address of your computer’s Ethernet adapter when you first  
access their network. This can prevent the Router (which has a different MAC address) from  
being allowed access to the ISPs network (and the Internet). To clone the MAC address of your  
computer’s Ethernet adapter, press the “Clone MAC Address” button or enter the MAC  
Address manually.

use the default settings together with DHCP service to manage the IP settings for their private  
network. The IP address of the Router is the base address used for DHCP. In order to use the Router  
for DHCP on your LAN, the IP address pool used for DHCP must be compatible with the IP address of  
the Router. The IP addresses available in the DHCP IP address pool will change automatically if you  
change the IP address of the Router. See the next section for information on DHCP setup.  
LAN Settings window  
To change the LAN IP Address or Subnet Mask, type in the desired values and click the Apply  
button. Your web browser should automatically be redirected to the new IP address. You will asked  
to login again to the Router’s web manager.  
In addition, the Router can be configured to relay DNS from your ISP or another available service to  
workstations on your LAN. When DNS Relay is Enabled, the Router will accept DNS requests from  
hosts on the LAN and forward them to the ISP (or alternative) DNS servers. Alternatively, you may  
also disable the DNS relay and configure hosts on your LAN to use DNS servers directly. Most users,  
who are using the Router for DHCP service on the LAN and are using DNS servers on the ISP’s  
network, will leave DNS relay enabled.

HOME - DHCP  
The DHCP server is enabled by default for the Router’s Ethernet LAN interface. DHCP service will  
supply IP settings to workstations configured to automatically obtain IP settings that are connected  
to the Router though the Ethernet port. When the Router is used for DHCP it becomes the default  
gateway for DHCP client connected to it. Keep in mind that if you change the IP address of the  
Router the range of IP addresses in the pool used for DHCP on the LAN will also be changed. The IP  
address pool can be up to 253 IP addresses.  
DHCP window  
To display this window, click the DHCP button in left menu. Any active DHCP Clients appear at the  
top of the window in the DHCP Clients List. The IP address and MAC address for active DHCP clients  
are displayed in the list.  
The two options for DHCP service are as follows:  
-
-
You may use the Router as a DHCP server for your LAN.  
You can disable DHCP service and manually configure IP settings for workstations.  
Follow the instructions below according to which of the above DHCP options you want to use. When  
you have configured the DHCP Settings as you want them, click the Apply button to commit the new  
settings.

Use the Router for DHCP  
To use the built-in DHCP server, click to select the DHCP Server option if it is not already selected.  
The IP Address Pool settings can be adjusted. The Starting IP Address is the lowest available IP  
address. If you change the IP address of the Router this will change automatically to be 1 more that  
the IP address of the Router.  
The Ending IP Address is the highest IP address number in the pool. Select the desired Lease Time  
from the drop-down menu. This is the amount of time that a workstation is allowed to reserve an IP  
address in the pool if the workstation is disconnected from the network or powered off.  
Disable the DHCP Server  
To disable DHCP, click the Disabled DHCP Server radio button and then click the Apply button.  
Choosing this option requires that workstations on the local network must be configured manually or  
use another DHCP server to obtain IP settings.  
If you configure IP settings manually, make sure to use IP addresses in the subnet of the Router. You  
will need to use the Router’s IP address as the Default Gateway for the workstation in order to  
provide Internet access.  
Create Static DHCP Server rules  
You can also create static DHCP Server rules to assign the same IP address every time to the same  
network client. To create a static DHCP Server rule, enter the MAC Address of the network client in  
the MAC Address field, or select it from the DHCP Client list if it is connected and press the Clone  
button.  
Enter the IP Address you want to use for the network client. Enter the Hostname for the network  
client and set the Static DHCP to Enabled. Click Apply to save the static DHCP rule.  
Note: If you want to use the Wake-on-LAN feature of the router, make sure you have defined the  
network clients you want to wake in the Static DHCP Server rules.

Menu - Advanced  
The Advanced folder contains main windows for Virtual Server, Special Applications, Firewall Rules,  
DMZ, IP Filters, MAC Filters, URL Blocking, Domain Blocking, Wireless Performance, and Dynamic  
DNS.  
ADVANCED – VIRTUAL SERVER  
Use this window to set up forwarding rules applied to inbound (WAN-to-LAN) traffic. The Virtual  
Server function allows remote users to access services on your LAN such as FTP for file transfers or  
SMTP and POP3 for e-mail. The Wireless Broadband Router will accept remote requests for these  
services at your Global IP Address, using the specified TCP or UDP protocol and port number, and  
then redirect these requests to the server on your LAN with the LAN IP address you specify.  
Remember that the specified Private IP Address must be within the useable range of the subnet  
occupied by the Router.  
UDP/TCP port redirection is used to direct inbound traffic to the specified servers or workstations  
on your private network. Port redirection can also be used to direct potentially hazardous packets  
to a proxy server outside your firewall. For example, you can configure the Router to direct HTTP  
packets to a designated HTTP server in the DMZ. You can define a set of instructions for a specific  
incoming port or for a range of incoming ports. Each set of instructions or rule is indexed and can be  
modified or deleted later as needed.  
Below you will find a list of some common used ports and their corresponding application:

Note: When you are using an application which supports UPnP Port Mapping, the router can be  
automatically configured by the application when needed. In that case, you don’t need to  
setup your port mappings manually.  
Note: When using Virtual Server rules, it is advised to configure the computer(s) with a Fixed IP  
Address instead of a Dynamic IP Address.

ADVANCED - DDNS  
The Router supports DDNS (Dynamic Domain Name Service). The Dynamic DNS service allows a  
dynamic public IP address to be associated with a static host name in any of the many domains,  
allowing access to a specified host from various locations on the Internet. This is enabled to allow  
remote access to a host by clicking a hyperlinked URL in the form hostname.dyndns.org, Many ISPs  
assign public IP addresses using DHCP, and this can make it difficult to locate a specific host on the  
LAN using standard DNS. If for example you are running a public web server or VPN server on your  
LAN, this ensures that the host can be located from the Internet if the public IP address changes.  
DDNS requires that an account be set up with one of the supported DDNS providers.

LICENCE AGREEMENT  
GNU GENERAL PUBLIC LICENSE  
Version 2, June 1991  
Copyright (C) 1989, 1991 Free Software Foundation, Inc.  
Temple Place, Suite 330, Boston, MA 02111-1307 USA  
Everyone is permitted to copy and distribute verbatim copies  
of this license document, but changing it is not allowed.  
Preamble  
The licenses for most software are designed to take away your freedom to share and change it. By  
contrast, the GNU General Public License is intended to guarantee your freedom to share and  
change free software--to make sure the software is free for all its users. This General Public  
License applies to most of the Free Software Foundation's software and to any other program whose  
authors commit to using it. (Some other Free Software Foundation software is covered by the GNU  
Library General Public License instead.) You can apply it to your programs, too.  
When we speak of free software, we are referring to freedom, not price. Our General Public  
Licenses are designed to make sure that you have the freedom to distribute copies of free software  
(and charge for this service if you wish), that you receive source code or can get it if you want it,  
that you can change the software or use pieces of it in new free programs; and that you know you  
can do these things.  
To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or  
to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if  
you distribute copies of the software, or if you modify it.  
For example, if you distribute copies of such a program, whether gratis or for a fee, you must give  
the recipients all the rights that you have. You must make sure that they, too, receive or can get  
the source code. And you must show them these terms so they know their rights.  
We protect your rights with two steps: (1) copyright the software, and (2) offer you this license  
which gives you legal permission to copy, distribute and/or modify the software.  
Also, for each author's protection and ours, we want to make certain that everyone understands  
that there is no warranty for this free software. If the software is modified by someone else and  
passed on, we want its recipients to know that what they have is not the original, so that any  
problems introduced by others will not reflect on the original authors' reputations.  
Finally, any free program is threatened constantly by software patents. We wish to avoid the  
danger that redistributors of a free program will individually obtain patent licenses, in effect  
making the program proprietary. To prevent this, we have made it clear that any patent must be  
licensed for everyone's free use or not licensed at all.  
The precise terms and conditions for copying, distribution and modification follow.  
GNU GENERAL PUBLIC LICENSE  
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION  
0. This License applies to any program or other work which contains a notice placed by the  
copyright holder saying it may be distributed under the terms of this General Public License. The  
"Program", below, refers to any such program or work, and a "work based on the Program" means  
72

LICENCE AGREEMENT  
either the Program or any derivative work under copyright law: that is to say, a work containing the  
Program or a portion of it, either verbatim or with modifications and/or translated into another  
language. (Hereinafter, translation is included without limitation in the term "modification".) Each  
licensee is addressed as "you".  
Activities other than copying, distribution and modification are not covered by this License; they  
are outside its scope. The act of running the Program is not restricted, and the output from the  
Program is covered only if its contents constitute a work based on the Program (independent of  
having been made by running the Program). Whether that is true depends on what the Program  
does.  
1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in  
any medium, provided that you conspicuously and appropriately publish on each copy an  
appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to  
this License and to the absence of any warranty; and give any other recipients of the Program a  
copy of this License along with the Program.  
You may charge a fee for the physical act of transferring a copy, and you may at your option offer  
warranty protection in exchange for a fee.  
2. You may modify your copy or copies of the Program or any portion of it, thus forming a work  
based on the Program, and copy and distribute such modifications or work under the terms of  
Section 1 above, provided that you also meet all of these conditions:  
a) You must cause the modified files to carry prominent notices stating that you changed the files  
and the date of any change.  
b) You must cause any work that you distribute or publish, that in whole or in part contains or is  
derived from the Program or any part thereof, to be licensed as a whole at no charge to all third  
parties under the terms of this License.  
c) If the modified program normally reads commands interactively when run, you must cause it,  
when started running for such interactive use in the most ordinary way, to print or display an  
announcement including an appropriate copyright notice and a notice that there is no warranty (or  
else, saying that you provide a warranty) and that users may redistribute the program under these  
conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself  
is interactive but does not normally print such an announcement, your work based on the Program is  
not required to print an announcement.)  
These requirements apply to the modified work as a whole. If identifiable sections of that work are  
not derived from the Program, and can be reasonably considered independent and separate works in  
themselves, then this License, and its terms, do not apply to those sections when you distribute  
them as separate works. But when you distribute the same sections as part of a whole which is a  
work based on the Program, the distribution of the whole must be on the terms of this License,  
whose permissions for other licensees extend to the entire whole, and thus to each and every part  
regardless of who wrote it.  
Thus, it is not the intent of this section to claim rights or contest your rights to work written  
entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or  
collective works based on the Program.  
In addition, mere aggregation of another work not based on the Program with the Program (or with  
a work based on the Program) on a volume of a storage or distribution medium does not bring the  
other work under the scope of this License.

LICENCE AGREEMENT  
3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code  
or executable form under the terms of Sections 1 and 2 above provided that you also do one of the  
following:  
a) Accompany it with the complete corresponding machine-readable source code, which must be  
distributed under the terms of Sections 1 and 2 above on a medium customarily used for software  
interchange; or,  
b) Accompany it with a written offer, valid for at least three years, to give any third party, for a  
charge no more than your cost of physically performing source distribution, a complete machine-  
readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and  
2 above on a medium customarily used for software interchange; or,  
c) Accompany it with the information you received as to the offer to distribute corresponding  
source code. (This alternative is allowed only for noncommercial distribution and only if you  
received the program in object code or executable form with such an offer, in accord with  
Subsection b above.)  
The source code for a work means the preferred form of the work for making modifications to it.  
For an executable work, complete source code means all the source code for all modules it  
contains, plus any associated interface definition files, plus the scripts used to control compilation  
and installation of the executable. However, as a special exception, the source code distributed  
need not include anything that is normally distributed (in either source or binary form) with the  
major components (compiler, kernel, and so on) of the operating system on which the executable  
runs, unless that component itself accompanies the executable.  
If distribution of executable or object code is made by offering access to copy from a designated  
place, then offering equivalent access to copy the source code from the same place counts as  
distribution of the source code, even though third parties are not compelled to copy the source  
along with the object code.  
4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided  
under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is  
void, and will automatically terminate your rights under this License. However, parties who have  
received copies, or rights, from you under this License will not have their licenses terminated so  
long as such parties remain in full compliance.  
5. You are not required to accept this License, since you have not signed it. However, nothing else  
grants you permission to modify or distribute the Program or its derivative works. These actions are  
prohibited by law if you do not accept this License. Therefore, by modifying or distributing the  
Program (or any work based on the Program), you indicate your acceptance of this License to do so,  
and all its terms and conditions for copying, distributing or modifying the Program or works based  
on it.  
6. Each time you redistribute the Program (or any work based on the Program), the recipient  
automatically receives a license from the original licensor to copy, distribute or modify the Program  
subject to these terms and conditions. You may not impose any further restrictions on the  
recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance  
by third parties to this License.  
7. If, as a consequence of a court judgment or allegation of patent infringement or for any other  
reason (not limited to patent issues), conditions are imposed on you (whether by court order,  
agreement or otherwise) that contradict the conditions of this License, they do not excuse you from  
74

LICENCE AGREEMENT  
the conditions of this License. If you cannot distribute so as to satisfy simultaneously your  
obligations under this License and any other pertinent obligations, then as a consequence you may  
not distribute the Program at all. For example, if a patent license would not permit royalty-free  
redistribution of the Program by all those who receive copies directly or indirectly through you,  
then the only way you could satisfy both it and this License would be to refrain entirely from  
distribution of the Program.  
If any portion of this section is held invalid or unenforceable under any particular circumstance, the  
balance of the section is intended to apply and the section as a whole is intended to apply in other  
circumstances. It is not the purpose of this section to induce you to infringe any patents or other  
property right claims or to contest validity of any such claims; this section has the sole purpose of  
protecting the integrity of the free software distribution system, which is implemented by public  
license practices. Many people have made generous contributions to the wide range of software  
distributed through that system in reliance on consistent application of that system; it is up to the  
author/donor to decide if he or she is willing to distribute software through any other system and a  
licensee cannot impose that choice.  
This section is intended to make thoroughly clear what is believed to be a consequence of the rest  
of this License.  
8. If the distribution and/or use of the Program is restricted in certain countries either by patents  
or by copyrighted interfaces, the original copyright holder who places the Program under this  
License may add an explicit geographical distribution limitation excluding those countries, so that  
distribution is permitted only in or among countries not thus excluded. In such case, this License  
incorporates the limitation as if written in the body of this License.  
9. The Free Software Foundation may publish revised and/or new versions of the General Public  
License from time to time. Such new versions will be similar in spirit to the present version, but  
may differ in detail to address new problems or concerns.  
Each version is given a distinguishing version number. If the Program specifies a version number of  
this License which applies to it and "any later version", you have the option of following the terms  
and conditions either of that version or of any later version published by the Free Software  
Foundation. If the Program does not specify a version number of this License, you may choose any  
version ever published by the Free Software Foundation.  
10. If you wish to incorporate parts of the Program into other free programs whose distribution  
conditions are different, write to the author to ask for permission. For software which is  
copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes  
make exceptions for this. Our decision will be guided by the two goals of preserving the free status  
of all derivatives of our free software and of promoting the sharing and reuse of software generally.  
NO WARRANTY  
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE  
PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN  
WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS"  
WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED  
TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  
THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD  
THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR  
CORRECTION.

LICENCE AGREEMENT  
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY  
COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM  
AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,  
INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE  
PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE  
OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH  
ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE  
POSSIBILITY OF SUCH DAMAGES.  
END OF TERMS AND CONDITIONS  
How to Apply These Terms to Your New Programs  
If you develop a new program, and you want it to be of the greatest possible use to the public, the  
best way to achieve this is to make it free software which everyone can redistribute and change  
under these terms.  
To do so, attach the following notices to the program. It is safest to attach them to the start of  
each source file to most effectively convey the exclusion of warranty; and each file should have at  
least the "copyright" line and a pointer to where the full notice is found.  
, 1 April 1989  
Ty Coon, President of Vice  
This General Public License does not permit incorporating your program into proprietary programs.  
If your program is a subroutine library, you may consider it more useful to permit linking proprietary  
applications with the library. If this is what you want to do, use the GNU Library General Public  
License instead of this License.
