PowerSourceWarning
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.
EliminateAC MainsOverloads
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.

IMPORTANT SAFETY INSTRUCTIONS
viii 78-4011351-01 Rev B
Prevent Power Cord Damage
Protect the power cord from being walked on or pinched, particularly at plugs, convenience
receptacles, and the point where the cord exits from the apparatus.
Handling Optional, Rechargeable Battery
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.
Provide Ventilation and Select a Location
Do not block any ventilation openings. Install in accordance with the manufacturer's instructions.
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 near any heat sources such as radiators, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.
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.
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
78-4011351-01 Rev B ix
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.

FCCPart68
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.
