Federal Communications Commission (FCC) Compliance Notice:

Radio Frequency Notice

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.

2. This device must accept any interference received, including interference that may cause undesired

operation.

Placement and Range Guidelines

Indoors, computers can connect over 802.11 wireless networks at a maximum range of 500 feet (152.4 m)

for 802.11b devices. However, the operating distance or range of your wireless connection can vary

significantly, based on the physical placement of the wireless access point.

For best results, identify a location for your wireless access point according to these guidelines:

• Away from potential sources of interference, such as PCs, large metal surfaces, microwaves, and 2.4 GHz cordless

phones.

• In an elevated location such as a high shelf that is near the center of the wireless coverage area for all mobile

devices.

Failure to follow these guidelines can result in significant performance degradation or inability to wirelessly

connect to the wireless access point.

To meet FCC and other national safety guidelines for RF exposure, the antennas for this device must be

installed to ensure a minimum separation distance of 20cm (7.9 in.) from persons. Further, the antennas shall

not be colocated with other transmitting structures.
