Chapter 6, page 99, Paragraph titled "Radio Frequency Interference Requirements"
The text currently reads:
"This device has been tested and found to comply with the limits for a Class A Digital Device,
pursuant to Part 15 of the Federal Communications Commission's Rules and Regulations."
The text should read:
"This device has been tested and found to comply with the limits for a Class B Digital Device,
pursuant to Part 15 of the Federal Communications Commission's Rules and Regulations."
The following information should be appended to the "Radio Frequency Interference Requirements" section:
"Radiation Exposure Statement
This equipment shall only be installed and operated with the antenna types shown below, with
gains not more than those shown below for each of the antennas, respectively, and installed with a
minimum of 20 cm of separation distance between the antenna and all persons during normal
operation.
Per FCC 1.1310 Table 1B, the maximum permissible RF exposure for an uncontrolled
environment is 1 mW/cm2 for the frequencies used in this device. The worst case power at the
center frequency of the band of operation is used for the calculation below. The power density
at a 20 cm distance is shown for each of the antenna options. As shown, the calculated power
density is well below the FCC's limit. The actual power density for the EUT calculated as
shown below.
