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.

• 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 systems 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.

• 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.

• 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.

• 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 cable modem 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 cable modem when disconnecting or reconnecting the Ethernet cable from the cable modem or

user's computer.

• It is recommended that the customer install an AC surge protector in the AC outlet to which this device is connected. 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.

• Do not use this product near water: for example, near a bathtub, washbowl, kitchen sink, or laundry tub, in a wet basement, or near a swimming pool.

• 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 due to lightning and power

surges.
