• n 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, Ethernet and
Phone lines.
• When the Cable Modem is connected to a local computer through 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 spec-
ifications.
• Ensure proper ventillation. Position the Cable Modem so that air flows freely
around it and the ventillation holes on the unit are not blocked.
• Do not mount the Cable Modem on surfaces that are sensitive to heat and/or
which may be damaged by the heat generated by the modem, its power
supply, or other accessories.

(FCC) rules. These requirements are intended 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 ac-
cordance with the instructions, may cause harmful interference to radio communi-
cations. However, there is no guarantee that interference will not occur in a
particular installation. f 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 fol-
lowing measures:
• Reorient or relocate the receiving antenna.
• ncrease the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which

Items You Need
f you are installing the Cable Modem yourself, make sure you have the following
items on hand before continuing:
•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. t 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 Cable Modem. The coax should be long enough
to reach from your Cable Modem to the nearest cable outlet.
Note: For best performance, use high-quality RG-6 type coax cable and mini-
mize or eliminate splitters between the cable jack and the Cable Modem.
•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 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.
•Wall-mount hardware (optional): if you want to wall-mount your Cable
Modem, you need to obtain two drywall anchors or wood screws. See the
Wall-Mount Template and nstructions for more details.
•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.
