Safety and Regulatory Information
Important Safety Instructions
Read This Before You Begin— When using your equipment, basic safety precautions should
always be followed to reduce the risk of fire, electric shock, and injury to persons, including
the following:
Read all of the instructions listed here and/or in the user manual before you operate this
device. Give particular attention to all safety precautions. Retain the instructions for
future reference.
This device must be installed and used in strict accordance with manufacturer’s
instructions, as described in the user documentation that is included with the device.
Chapter 1
Comply with all warning and caution statements in the instructions. Observe all warning
and caution symbols that are affixed to this device.
To prevent fire or shock hazard, do not expose this device to rain or moisture. The device
must not be exposed to dripping or splashing. Do not place objects filled with liquids, such
as vases, on the device.
This device was qualified under test conditions that included the use of the supplied
cables between system components. To ensure regulatory and safety compliance, use
only the provided power and interface cables and install them properly.
Different types of cord sets may be used for connections to the main POWER supply
circuit. Use only a main line cord that complies with all applicable device safety
requirements of the country of use.
Installation of this device must be in accordance with national wiring codes and conform
to local regulations.
Operate this device only from the type of power source indicated on the device’s marking
label. If you are not sure of the type of power supplied to your home, consult your dealer
or local power company.
Do not overload outlets or extension cords, as this can result in a risk of fire or electric
shock. Overloaded AC outlets, extension cords, frayed power cords, damaged or cracked
wire insulation, and broken plugs are dangerous. They may result in a shock or fire hazard.
Route power supply cords so that they are not likely to be walked on or pinched by items
placed upon or against them. Pay particular attention to cords where they are attached to
plugs and convenience receptacles, and examine the point where they exit from the
device.

Place this device in a location that is close enough to an electrical outlet to accommodate
the length of the power cord.
Place the device to allow for easy access when disconnecting the power cord of the device
from the AC wall outlet.
Do not connect the plug into an extension cord, receptacle, or other outlet unless the plug
can be fully inserted with no part of the blades exposed.
Place this device on a stable surface.
Avoid damaging the device with static by touching the coaxial cable when it is attached to
the earth-grounded coaxial cable-TV wall outlet.
Always first touch the coaxial cable connector on the device when disconnecting or
reconnecting the Ethernet cable from the device or user’s PC.
Installation of an AC surge protector in the AC outlet to which this device is connected is
recommended. This is to avoid damaging the device by local lightning strikes and other
electrical surges.
Postpone installation until there is no risk of thunderstorm or lightning activity in the area.
Avoid using a telephone (other than a cordless type) during an electrical storm. There is a
remote risk of electric shock from lightning. For added protection, unplug the device from
the wall outlet and disconnect the cables to avoid damage to this device from lightning
and power surges.

Do not cover the device or block the airflow to the device with any other objects. Keep the
device away from excessive heat and humidity and keep the device free from vibration
and dust.
Wipe the device with a clean, dry cloth. Never use cleaning fluid or similar chemicals. Do
not spray cleaners directly on the device or use forced air to remove dust.
For added protection, unplug the device from the wall outlet and disconnect the cables to
avoid damage to this device during lightning activity or power surges.
CAUTION: To reduce the risk of fire, use only No. 26 AWG or larger (e.g., 24 AWG) UL
Listed or CSA Certified Telecommunication Line Cord, or national equivalent.
Upon completion of any service or repairs to this device, ask the service technician to
perform safety checks to determine that the device is in safe operating condition.
Do not open the device. Do not perform any servicing other than that contained in the
installation and troubleshooting instructions. Refer all servicing to qualified service
personnel.
