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 radio interference in a
commercial environment. This equipment can generate, use and radiate radio frequency energy and, if not
installed and used in accordance with the instructions in this manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause interference, in which case
the user, at his own expense, will be required to take whatever measures are necessary to correct the
interference. If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one
of the following measures:
y
Reorient or relocate the receiving antenna.
y
Increase the separation between the equipment and receiver.
y
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
y
Consult the dealer or an experienced radio/TV technician for help.
The 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 the party responsible for compliance
could void the user’s authority to operate this equipment.
IEEE 802.11b or 802.11g operation of this product in the U.S.A is firmware-limited to channels 1 through 11.
IMPORTANT NOTE:
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This
equipment should be installed and operated with minimum distance 20cm between the radiator & your body.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
The availability of some specific channels and/or operational frequency bands are country dependent and are
firmware programmed at the factory to match the intended destination. The firmware setting is not accessible by
the end user.
Note to CATV System Installer - This reminder is provided to call the CATV systems installer's attention to
Section 820-93 of the National Electric Code which provide guideline for proper grounding and, in particular,
specify that the Coaxial cable shield shall be connected to the grounding system of the building, as close to the
point of cable entry as practical.
