Safety Requirements
ARRIS Wideband Cable Modems comply with the applicable requirements for per-
formance, construction, labeling, and information when used as outlined below:
CAUTION
Risk of shock
Mains voltages inside this unit. No user serviceable parts inside. Refer
service to qualified personnel only!
CAUTION
Risk of damage
To prevent overheating your Wideband Cable Modem, do not block the
ventilation holes on the unit.
Do not locate the equipment within 6 feet (1.9m) of a flame or ignition source (e.g.
heat registers, space heaters, fireplaces, etc.).

swimming pool, etc.), to avoid risk of electrocution.
• Avoid using and/or connecting the equipment during an electrical storm, to
avoid risk of electrocution.
• Use only power supply and power cord included with the equipment.
• Equipment should be installed near the power outlet and should be easily
accessible.
• The shield of the coaxial cable must be connected to earth (grounded) at the
entrance to the building in accordance with applicable national electrical in-
stallation codes. In the U.S., this is required by NFPA 70 (National Electrical
Code) Article 820. In the European Union and in certain other countries,
CATV installation equipotential bonding requirements are specified in IEC

If the equipment is to be installed in an area serviced by an IT power line
network, as is found in many areas of Norway, special attention should be
given that the installation is in accordance with IEC 60728-11, in particular
Annex B and Figure B.4.
• In areas of high surge events or poor grounding situations and areas prone
to lightning strikes, additional surge protection may be required (i.e.
PF11VNT3 from American Power Conversion) on the AC, RF, and Ethernet
lines.
• When the Wideband Cable Modem is connected to a local computer through
USB or Ethernet cables, the computer must be properly grounded to the
building/residence AC ground network. All plug-in cards within the computer
must be properly installed and grounded to the computer frame per the
manufacturer’s specifications.
• Do not use spray cleaners or aerosols on the Wideband Cable Modem.
• Clean the Wideband Cable Modem only with a dry cloth.

Items You Need
If you are installing the Wideband Cable Modem yourself, make sure you have the
following items on hand before continuing:
•Wideband Cable Modem package: see What’s in the Box? for a list of
items in the package.
•Coaxial cable (coax): as shown in the image to the left, this is a thin cable
with a connector on each end. It is the same kind of wire used to connect to
your television for cable TV. You can buy coax from any electronics retailer
and many discount stores; make sure it has connectors on both ends. There
are two types of connectors, slip-on and screw-on; the screw-on connectors
are best for use with your Wideband Cable Modem. The coax should be long
enough to reach from your Wideband Cable Modem to the nearest cable out-
let.
•Splitter (optional): provides an extra cable connection by splitting a sin-
gle outlet into two. You may need a splitter if you have a TV already con-
nected to the cable outlet that you want to use. You can buy a splitter from
any electronics retailer and most discount stores; you may also need a short
piece of coax cable (with connectors); use it to connect the splitter to the
cable outlet and then connect the Wideband Cable Modem and TV to the
splitter.
Note: A splitter effectively cuts the signal in half and sends each half to its
two outputs. Using several splitters in a line may deteriorate the quality of
your television and/or internet connection.
•Information packet: your cable company should furnish you with a packet
containing information about your service and how to set it up. Read this in-
formation carefully and contact your cable company if you have any ques-
tions.

System Requirements
The Touchstone Wideband Cable Modem operates with most computers. The fol-
lowing describes requirements for each operating system; see the documentation
for your system for details on enabling and configuring networking.
To use the Wideband Cable Modem, you need DOCSIS 3.0 high-speed Internet serv-
ice from your cable company.
Recommended Hardware
The following hardware configuration is the minimum recommended. Computers
not meeting this configuration can still work with the WBM750, but may not be able
to make maximum use of WBM750 throughput.
CPU: P4, 3G z or faster
RAM: 1GB or greater
ard drive: 7200 RPM or faster
Ethernet: Gig-E (1000BaseT)
Windows
Ethernet connection: Windows 98, Windows 98 SE (Second Edition), Windows ME,
Windows 2000, Windows XP, or Windows Vista
USB connection (if equipped): Windows 2000, Windows XP, or Windows Vista
Note: For best results, Windows XP should be configured with a TCP receive
window size of 256KB (the XP default is 64 KB). The TCP Optimizer pro-
gram, available from speedguide.net, can be used to make this change.
MacOS
Ethernet connection only: MacOS X
inux/other Unix
Ethernet connection only: ardware drivers, TCP/IP, and D CP must be enabled in
the kernel

Ethernet or USB?
There are two ways to connect your computer (or other equipment) to the Wide-
band Cable Modem. The following will help you decide which is best for you:
Ethernet
Ethernet is a standard method of connecting two or more devices into a Local Area
Network (LAN). Use the Ethernet connection if your computer has built-in Ethernet
hardware, does not use Windows, or you want to share the Wideband Cable Modem
connection with several computers.
Note: To connect two or more computers to the Ethernet port, you will need a
hub or broadband router (available at computer retailers).
The Wideband Cable Modem package comes with a 6-foot (1.9m) Ethernet cable
(the connectors look like wide telephone connectors); you can purchase a longer
cable if necessary at a computer retailer. If you are connecting the Wideband Cable
Modem directly to a computer, or to an Ethernet hub or broadband router with a
cross-over switch, ask for Category 5 (CAT5) straight-through cable. If you are con-
necting the Wideband Cable Modem to an Ethernet hub or broadband router with-
out a crossover switch, ask for a Category 5 crossover cable.
USB
USB (Universal Serial Bus) is meant for connecting a variety of accessories, such as
keyboards, mice, printers, and communications devices (including Wideband Cable
Modems) to a single computer. Use the USB connection if you have only one com-
puter, and the computer is using a Windows operating system (Windows 2000 or
later), and has no built-in Ethernet hardware. Wideband Cable Modems with USB
ports include a 5-foot (1.6m) USB cable.
Both
If you have two or more computers, you can connect one computer to the Wide-
band Cable Modem’s USB port and one or more other computers to the Ethernet
port. To connect two or more computers to the Ethernet port, you will need a hub
or broadband router (available at computer retailers).
For more information about connecting two or more computers, contact your cable
service provider.

What About Security?
aving a high-speed, always-on connection to the Internet requires a certain
amount of responsibility to other Internet users—including the need to maintain a
reasonably secure system. While no system is 100% secure, you can use the fol-
lowing tips to enhance your system’s security:
• Keep your operating system updated with the latest security patches. Run
the system update utility at least weekly.
• Keep your email program updated with the latest security patches. In addi-
tion, avoid opening email containing attachments, or opening files sent
through chat rooms, whenever possible.
• Install a virus checker and keep it updated.
• Avoid providing web or file-sharing services over your Wideband Cable
Modem. Besides certain vulnerability problems, most cable companies pro-
hibit running servers on consumer-level accounts and may suspend your ac-
count for violating your terms of service.
• Use the cable company’s mail servers for sending email.
• Avoid using proxy software unless you are certain that it is not open for
abuse by other Internet users (some are shipped open by default). Crimi-
nals can take advantage of open proxies to hide their identity when break-
ing into other computers or sending spam. If you have an open proxy, your
cable company may suspend your account to protect the rest of the net-
work.
• If you connect your Wideband Cable Modem to a wireless LAN, make sure
you enable security and encryption on the wireless hub (for the same rea-
sons that you should run only secured proxies). Consult the documentation
and technical support of the wireless equipment provider for help.
