A label on this product indicates the correct power source for this product. Operate this product only
from an electrical outlet with the voltage and frequency indicated on the product label. If you are
uncertain of the type of power supply to your home or business, consult your service provider or your
local power company.
The AC inlet on the unit must remain accessible and operable at all times.
Ground the Product
WARNING: Avoid electric shock and fire hazard! Do not defeat the safety purpose of
the polarized or grounding-type plug. A polarized plug has two blades with one wider
than the other. A grounding-type plug has two blades and a third grounding prong.
The wide blade or the third prong is provided for your safety. If the provided plug
does not fit into your outlet, consult an electrician for replacement of the obsolete
outlet.
If this product connects to coaxial cable wiring, be sure the cable system is grounded (earthed). Grounding provides
some protection against voltage surges and built-up static charges.
Protect the Product from Lightning
For added protection, unplug this apparatus during lightning storms or when unused for long periods
of time. In addition to disconnecting the AC power from the wall outlet, disconnect the signal inputs.
Verify the Power Source from the On/Off Power Light
When the on/off power light is not illuminated, the apparatus may still be connected to the power
source. The light goes out when the apparatus is turned off, regardless of whether it is still plugged into
an AC power source.
Eliminate AC Mains Overloads
WARNING: Avoid electric shock and fire hazard! Do not overload AC mains, outlets,
extension cords, or integral convenience receptacles. For products that require battery
power or other power sources to operate them, refer to the operating instructions for
those products.

This product may contain a rechargeable Lithium-Ion battery to provide stand-by operation in the
event of an AC power failure. Heed the following warning and see the instructions later in this guide
for handling, replacing, and disposing of the battery.
WARNING: There is danger of explosion if the battery is mishandled or incorrectly
replaced. Replace only with the same type of battery. Do not disassemble it or attempt
to recharge it outside the system. Do not crush, puncture, dispose of in fire, short the
external contacts, or expose to water or other liquids. Dispose of the battery in
accordance with local regulations and instructions from your service provider.

provides proper ventilation.
Do not place entertainment devices (such as VCRs or DVDs), lamps, books, vases with liquids, or
other objects on top of this product.
Protect from Exposure to Moisture and Foreign Objects
Do not use this apparatus near water.
WARNING: Avoid electric shock and fire hazard! Do not expose this product to
liquids, rain, or moisture.
WARNING: Avoid electric shock and fire hazard! Unplug this product before cleaning.
Clean only with a dry cloth. Do not use a liquid cleaner or an aerosol cleaner. Do not
use a magnetic/static cleaning device (dust remover) to clean this product.
WARNING: Avoid electric shock and fire hazard! Never push objects through the
openings in this product. Foreign objects can cause electrical shorts that can result in
electric shock or fire.

IMPORTANT SAFETY INSTRUCTIONS
Accessories Warning
WARNING: Avoid electric shock and fire hazard! Only use attachments/accessories
specified by your service provider or the manufacturer.
Service Warnings
WARNING: Avoid electric shock! Do not open the cover of this product. Opening or
removing the cover may expose you to dangerous voltages. If you open the cover, your
warranty will be void. This product contains no user-serviceable parts. Refer all
servicing to qualified service personnel.
Servicing is required when the apparatus has been damaged in any way, such as a power-supply cord
or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has
been exposed to rain or moisture, does not operate normally, or has been dropped.
Check Product Safety
Upon completion of any service or repairs to this product, the service technician must perform safety
checks to determine that this product is in proper operating condition.
Protect the Product When Moving It
Always disconnect the power source when moving the apparatus or connecting or disconnecting
cables.
WARNING: Avoid personal injury and damage to this product! Use only with the cart,
stand, tripod, bracket, or table specified by the manufacturer or sold with the
apparatus. When a cart is used, use caution when moving the cart / apparatus
combination to avoid injury from tip-over.

the cable modem. AC power must be available to recharge the optional battery.
2 DS (Downstream) – Indicates the status of the connection for receiving data.
Illuminates during normal operation
3 US (Upstream) – Indicates the status of the connection for sending data.
Illuminates during normal operation
4 ONLINE – Illuminates solid green when the cable modem is registered on the
network and fully operational. This indicator blinks to indicate one of the
following conditions:
The cable modem is booting up and not ready for data
The cable modem is scanning the network and attempting to register
The cable modem has lost registration on the network and will continue
blinking until it registers again

Front Panel Description
Notes:
After the cable modem is successfully registered on the network, the POWER
(LED 1), DS (LED 2), US (LED 3), and ONLINE (LED 4) LEDs illuminate
continuously to indicate that the cable mode is active and fully operational
LEDs may behave differently when the cable modem is running on battery
power (without AC power-optional model only). Most LEDs are disabled if
the unit is operating on battery power. In this mode, the POWER LED blinks
to indicate that the unit is operating under battery power but AC power has
failed

Where Is the Best Location for My Cable Modem?
Where Is the Best Location for My Cable Modem?
The ideal location for your cable modem is where it has access to outlets and other
devices. Think about the layout of your home or office, and consult with your
service provider to select the best location for your cable modem. Read this user's
guide thoroughly before you decide where to place your cable modem.
Consider these recommendations:
Position your PC and cable modem so that they are located near an AC power
outlet.
Position your PC and cable modem so that they are located near an existing cable
input connection to eliminate the need for an additional cable outlet. There
should be plenty of room to guide the cables away from the modem and the PC
without straining or crimping them.
Airflow around the cable modem should not be restricted.
Choose a location that protects the cable modem from accidental disturbance or
harm.

How Do I Set Up My High-Speed Internet Access Account?
How Do I Set Up My High-Speed Internet Access Account?
Before you can use your cable modem, you need to have a high-speed Internet
access account. If you do not have a high-speed Internet access account, you need to
set up an account with your local service provider. Choose one of the two options in
this section.
I Do Not Have a High-Speed Internet Access Account
If you do not have a high-speed Internet access account, your service provider will
set up your account and become your Internet Service Provider (ISP). Internet access
enables you to send and receive e-mail, access the World Wide Web, and receive
other Internet services.
You will need to give your service provider the following information:
The serial number of the modem
The Media Access Control (MAC) address of the modem
These numbers appear on a bar code label located on the cable modem. The serial
number consists of a series of alphanumeric characters preceded by S/N. The MAC
address consists of a series of alphanumeric characters preceded by CM MAC. The
following illustration shows a sample bar code label.
Write down these numbers in the space provided here.
Serial Number _______________________
MAC Address ________________________
I Already Have an Existing High-Speed Internet Access Account
If you have an existing high-speed Internet access account, you must give your
service provider the serial number and the MAC address of the cable modem. Refer
to the serial number and MAC address information listed previously in this section.
Note: You may not be able to continue to use your existing e-mail account with your
cable modem. Contact your service provider for more information.
