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 electrical 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.

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.
It is recommended that the customer install an electrical surge protector in the electrical
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

FCC STATEMENTS
FCC Interference Statement
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 environment. 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 device off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the device 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.
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.
FCC CAUTION: Any changes or modifications not expressly approved by Motorola for
compliance could void the user’s authority to operate the equipment.
FCC Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. To comply with the FCC RF exposure compliance requirements, the separation
distance between the antenna and any person’s body (including hands, wrists, feet and
ankles) must be at least 8 inches (20.3 centimeters).
This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter except those already approved in this filing.
