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 may go 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.

Remove all packaging material before applying power to the product.
Do not place this apparatus on a bed, sofa, rug, or similar surface.
Do not place this apparatus on an unstable surface.
Do not install this apparatus in an enclosure, such as a bookcase or rack, unless the installation
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.
Do not block ventilation openings.
Protect from Exposure to Moisture and Foreign Objects
WARNING: Avoid electric shock and fire hazard! Do not expose this product to
liquids, rain, or moisture. Do not expose this product to dripping or splashing liquids,
rain, or moisture. Objects filled with liquids, such as vases, should not be placed on

FCC Part 68
The Federal Communications Commission (FCC) of the United States restricts specific uses of
modems, and places registration responsibilities on both the manufacturer and the individual
user.
1The modem may not be connected to a party line or to a coin-operated telephone.
2Notification to the telephone company is no longer required prior to connecting
registered equipment, but upon request from the telephone company, the user shall tell
the telephone company which line the equipment is connected to as well as the
registration number and ringer equivalence number of the registered protective circuitry.
FCC information is printed on a label on the bottom of the modem.
IC (Industry Canada) Notice
Notice: The Industry Canada (formerly Canadian Department of Communications) label
identifies certified equipment. This certification means that the equipment meets certain
telecommunications network protective, operational, and safety requirements. The
department does not guarantee the equipment will operate to the user's satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to
the facilities of the local telecommunications company. The equipment must also be installed
using an acceptable method of connection. In some cases, the company's inside wiring
associated with a single-line individual service may be extended by means of a certified
connector assembly (telephone extension cord). The customer should be aware that
compliance with the above conditions may not prevent degradation of service in some
situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance
facility designated by the supplier. Any repairs or alterations made by the user may give the
telecommunications company cause to request the user to disconnect the equipment. Users
should ensure for their own protection that the electrical ground connections of the power
utility, telephone lines and internal metallic water pipe system, if present, are connected
together. This precaution may be particularly important in rural areas.
CAUTION:
Users should not attempt to make such connections themselves, but should
contact the appropriate electric inspection authority, or electrician, as
appropriate.

Where Is the Best Location for My DOCSIS Residential Gateway?
Where Is the Best Location for My DOCSIS Residential
Gateway?
The ideal location for your residential gateway 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 residential gateway. Read this
user guide thoroughly before you decide where to place your residential gateway.
Consider these recommendations:
Choose a location close to your computer if you will also use the residential
gateway for high-speed Internet service.
Choose a location that is near an existing RF coaxial connection to eliminate the
need for an additional RF coaxial outlet.
Choose a location for the residential gateway that is adjacent to your telephone
equipment if you are using only one or two pieces of telephone equipment.
Note: If you are using the residential gateway to provide service to several
telephones, a professional installer can connect the residential gateway to your
existing home telephone wiring. To minimize changes to the home telephone
wiring, you may want to locate the residential gateway near an existing
telephone outlet.
Choose a location that is relatively protected from accidental disturbance or
harm, such as a closet, basement, or other protected area.
Choose a location so that there is plenty of room to guide the cables away from
the modem without straining or crimping them.
Airflow around the residential gateway should not be restricted.
Read this user guide thoroughly before installing the residential gateway.

How Do I Mount the Modem on a Wall? (Optional)
How Do I Mount the Modem on a Wall? (Optional)
You can mount the residential gateway on a wall using two wall anchors, two
screws, and the mounting slots located on the unit. The modem can be mounted
vertically or horizontally.
Before You Begin
Before you begin, choose an appropriate mounting place. The wall can be made of
cement, wood, or drywall. The mounting location should be free of obstructions on
all sides, and the cables should be able to easily reach the residential gateway
without strain. Leave sufficient clearance between the bottom of the residential
gateway and any flooring or shelving underneath to allow access to cabling. In
addition, leave enough slack in all cables so that the residential gateway can be
removed for any required maintenance without disconnecting the cables. Also,
verify that you have the following items:
Two wall anchors for #8 x 1-inch screws
Two #8 x 1-inch pan head sheet metal screws
Drill with a 3/16-in. wood or masonry bit, as appropriate for the wall
composition
A copy of the wall-mounting illustrations shown on the following pages

Location and Dimensions of the Wall-Mounting Slots
The following illustration shows the location and dimensions of the wall-mounting
slots on the bottom of the modem. Use the information on this page as a guide for
mounting your modem to the wall.
Mounting the Residential Gateway on a Wall
1Using a drill with a 3/16-inch bit, drill two holes at the same height and 4 inches
apart.
Note: The preceding graphic illustrates the location of the mounting holes on the
back of the residential gateway.
2Are you mounting the residential gateway into a drywall or concrete surface
where a wooden stud is available?
If yes, go to step 3.
If no, drive the anchor bolts into the wall, and install the mounting screws
into the anchor bolts; leave a gap of about 1/4-inch between the screw head
and the wall. Then, go to step 4.
3Install the mounting screws into the wall; leave a gap of about 1/4-inch between
the screw head and the wall. Then, go to step 4.
4Verify that no cables or wires are connected to the residential gateway.

5Lift the residential gateway into position. Slip the large end of both mounting
slots (located in the back of the residential gateway) over the mounting screws,
and then slide the residential gateway down until the narrow end of the keyhole
slot contacts the screw shaft.
Important: Verify that the mounting screws securely support the residential
gateway before you release the unit.
