Safety Requirements
ARRIS Telephony Modems comply with the applicable requirements for
performance, construction, labeling, and information when used as
outlined below
:
• The Telephony Modem is designed to be connected directly to
a telephone.
• Connecting the Telephony Modem to the home's existing tele-
phone wiring should only be performed by a professional in-
staller.
• Do not use product near water (i.e. wet basement, bathtub,
sink or near a swimming pool, etc.), to avoid risk of electrocu-
tion.
• Avoid using and/or connecting the equipment during an electri-
cal storm, to avoid risk of electrocution.
• Do not locate the equipment within 6 feet (1.9 m) of a flame or
ignition source, to avoid damage or injury from battery explo-
sion (i.e. heat registers, space heaters, fireplaces, etc.).
• Use only power supply and power cord included with the equip-
ment.
• Equipment should be installed near the power outlet and should
be easily accessible. The coax drop cable’s shield must be
grounded at the building/residence either close to the point of
entrance or at the point of attachment. It should be grounded
as close as practical to the building/residence AC ground to
minimize grounding connector length and thereby limit the po-
tential voltage differences between the cable TV coax cable and
other grounding systems. Refer to the individual country’s Na-
tional Electric Code for further details.
• In areas of high surge events or poor grounding situations and
areas prone to lightning strikes, additional surge protection
may be required (i.e. PF11VNT3 from American Power Conver-
sion) on the AC, RF, Ethernet and Phone lines.
• When the Telephony Modem is connected to a local computer
through USB or Ethernet cables, the computer must be proper-
ly grounded to the building/residence AC ground network. All
plug-in cards within the computer must be properly installed
and grounded to the computer frame per the manufacturer’s
specifications.
CAUTION
Connecting the Telephony Modem to the home's
existing telephone wiring should only be performed
by a professional installer. Physical connections to
the previous telephone provider must be removed
and the wiring must be checked; there must not be
any voltages. Cancellation of telephone service is
not adequate. Failure to do so may result in loss of
service and/or permanent damage to the Telephony
Modem.
