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 installation. 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 equipment 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 equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to which the receiver is

Caution:

Changes or modifications not expressly approved by the party responsible for compliance could

void the user's authority to operate the equipment.

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment

and meets the FCC radio frequency (RF) Exposure Guidelines. This equipment has very low levels of RF

energy that it deemed to comply without maximum permissive exposure evaluation (MPE). But it is

desirable that it should be installed and operated keeping the radiator at least 20cm or more away from

person's body (excluding extremities: hands, wrists, feet and ankles).

5.15-5.35GHz band is restricted to indoor operations only.

Compliance with FCC requirement 15.407(c) Data transmission is always initiated by software, which is

the passed down through the MAC, through the digital and analog baseband, and finally to the RF chip.

Several special packets are initiated by the MAC. These are the only ways the digital baseband portion

will turn on the RF transmitter, which it then turns off at the end of the packet. Therefore, the transmitter

will be on only while one of the aforementioned packets is being transmitted. In other words, this device
