April 9 th , 2007 Kirby Munroe Advanced Compliance Solutions, Inc. 5015 B.U. Bowman Drive Buford, Georgia 30518 USA Kirby, Cirronet requests that our recent FCC Grant – HSW-2492 – be amended to include Portable operation. The WIT2492 radio certified under that ID was designed to be used in a wireless microphone transmitter that is worn on the hip of the user. As a result, the WIT2492 transmitter will be operating within 2.5 cm of a human body and requires a ‘portable’ designation. Per instructions from our TCB, in order to meet the more stringent FCC MPE requirements for portable operation, we are providing: • Information describing the radio operating conditions (Appendix 1). • Detailed calculations showing the maximum attainable transmit duty cycle and average power produced by the device (Appendices 2 and 3). • Updated verbiage in the user’s manual to satisfy RF exposure compliance with the new portable designation. Any questions or comments regarding this request should be sent to Mark Tucker, VP of Engineering. Regards, Mark Tucker VP of Engineering Cirronet

Frequency hopping spread spectrum technology ensures maximum resistance to noise and multipath fading and robustness in the presence of interfering signals, while operation in the 2.4GHz ISM band allows license free use and worldwide compliance. A simple serial interface supports asynchronous data up to 230400 bps. An on board 3 KB buffer and an error correcting over the air protocol provide smooth data flow and simplify the task of integration with existing applications. Manufacturer Information: Cirronet 3079 Premiere Parkway, Suite 140 Duluth, GA 30097 Detailed photographs of the EUT are filed separately with this filing. 1.2.2 Intended Use The WIT2492 radio transceiver provides reliable wireless connectivity for either point to point or multipoint applications. 1.3 Test Methodology and Considerations The Cirronet WIT2492 is a transmission systems that employs both frequency hopping (or channel changing) techniques using digitally modulated channels. Based on the FCC interpretation on devices which employ both techniques, the WIT2492 demonstrated compliance with the DTS standards of Part 15.247 only. According to the FCC interpretation, there is no need to demonstrate compliance with both the FHSS standards and the DTS standards. Because the WIT2492 utilizes antennas of multiple types and gains, the highest gain antenna for each type was tested. This device allows for the use of all antennas listed below without any reduction in output power as required by 15.247(b)(4). 1.4 Antenna List * Antennas of the highest gain of each type.

Frequency hopping spread spectrum technology ensures maximum resistance to noise and multipath fading and robustness in the presence of interfering signals, while operation in the 2.4GHz ISM band allows license free use and worldwide compliance. A simple serial interface supports asynchronous data up to 230400 bps. An on board 3 KB buffer and an error correcting over the air protocol provide smooth data flow and simplify the task of integration with existing applications. Manufacturer Information: Cirronet 3079 Premiere Parkway, Suite 140 Duluth, GA 30097 Detailed photographs of the EUT are filed separately with this filing. 1.2.2 Intended Use The WIT2492 radio transceiver provides reliable wireless connectivity for either point to point or multipoint applications. 1.3 Test Methodology and Considerations The Cirronet WIT2492 is a transmission systems that employs both frequency hopping (or channel changing) techniques using digitally modulated channels. Based on the FCC interpretation on devices which employ both techniques, the WIT2492 demonstrated compliance with the DTS standards of Part 15.247 only. According to the FCC interpretation, there is no need to demonstrate compliance with both the FHSS standards and the DTS standards. Because the WIT2492 utilizes antennas of multiple types and gains, the highest gain antenna for each type was tested. This device allows for the use of all antennas listed below without any reduction in output power as required by 15.247(b)(4). 1.4 Antenna List * Antennas of the highest gain of each type.
