SAFETY NOTICE
Device Grounding: 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

INSTALLING THE MODEM
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.
