SAFETY NOTICE
Device Grounding: The cable distribution system under consideration is a
TNV-1 circuit. The common sides or earthed side of the circuit are connected
to the screen of the coaxial cable through an antenna connector of tuner and
to all accessible parts and circuits (SELV, LCC and accessible metal parts). The
screen of the coaxial cable is intended to be connected to earth in the building
installation.
Install the cable modem to include grounding the coaxial cable to the earth
as close as practical to the building entrance per ANSI/NFPA 70 and the
National Electrical Code (NEC section 820.93, Grounding of the Outer
Conductive Shield of a Coaxial Cable). The device is designed for IT power
systems with phase-to-phase voltage at 120V.
This unit requires a 100-240V, 50-60Hz power adapter. The power adapter
must be keyed for proper polarization and must be fully inserted to contact
the back of the power connector port to ensure snug connection. Use only
the supplied power adapter.
Disconnecting the Device: If the cable modem becomes damaged or
encounters some other abnormality, disconnect the power adapter from the
AC wall outlet immediately.
Temperature and Altitude: Install the device in a location not to exceed the
maximum operating temperature of 104˚F (40˚C). Maximum operating
altitude is 5000 m (16,404 ft.).

Federal Communication Commission Interference Statement
This device complies with Part 15 of the FCC Rules. Operation is subject to
the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed 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 accordance with the
instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a
particular installation. If 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 of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: Any changes or modifications not expressly approved by the
party responsible for compliance could void the user's authority to operate
this equipment.
This transmitter must not be co-located or operating in conjunction with
any other antenna or transmitter.
Operations in the 5.15-5.25GHz band are restricted to indoor usage only.
Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated
with minimum distance 38cm between the radiator & your body.
Note: The country code selection is for non-US model only and is not
available to all US model. Per FCC regulation, all WiFi product marketed in
US must fixed to US operation channels only.
Industry Canada statement:
This device complies with ISED’s licence-exempt RSSs. Operation is subject
to the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
Le présent appareil est conforme aux CNR d’ ISED applicables aux appareils
radio exempts de licence. L’exploitation est autorisée aux deux conditions
suivantes : (1) le dispositif ne doit pas produire de brouillage préjudiciable,
et (2) ce dispositif doit accepter tout brouillage reçu, y compris un brouillage
susceptible de provoquer un fonctionnement indésirable.
Caution :
(i) the device for operation in the band 5150-5250 MHz is only for indoor
use to reduce the potential for harmful interference to co-channel mobile
satellite systems;
(ii) where applicable, antenna type(s), antenna models(s), and worst-case
tilt angle(s) necessary to remain compliant with the e.i.r.p. elevation mask
requirement set forth in section 6.2.2.3 shall be clearly indicated.
Avertissement:
Le guide d’utilisation des dispositifs pour réseaux locaux doit inclure des
instructions précises sur les restrictions susmentionnées, notamment :
(i) les dispositifs fonctionnant dans la bande 5150-5250 MHz sont réservés
uniquement pour une utilisation à l’intérieur afin de réduire les risques de
brouillage préjudiciable aux systèmes de satellites mobiles utilisant les
mêmes canaux;
(ii) lorsqu’il y a lieu, les types d’antennes (s’il y en a plusieurs), les numéros
de modèle de l’antenne et les pires angles d’inclinaison nécessaires pour
rester conforme à l’exigence de la p.i.r.e. applicable au masque d’élévation,
énoncée à la section 6.2.2.3, doivent être clairement indiqués

INSTALLING THE DG4244
1. Connect the coaxial cable (not supplied) to the Cable connector
on the rear panel of the modem and connect the other end to
the cable wall outlet. Do not bend or over tighten the cables, as
this may strain the connector and cause damage. To connect a
modem and a television to the same wall outlet, you must use
a cable line splitter (not included).
2. Connect the Ethernet cable (supplied) to an Ethernet port on
the back panel of the modem and connect the other end to the
Ethernet port of a PC. Use a Category 5e or Category 6 Ethernet
cable with RJ-45 connectors to ensure Gigabit Ethernet speeds
(if the computer supports it).
3. Connect the power adapter (supplied) to the Power port on the
modem. Connect the other end to a power outlet.
