SETTING NEW STANDARDS WORLDWIDE Message Centers • Time and Temperature Displays • Scoreboards For All Sports • Voting Systems Request for Confidential Treatment – HS-200 Wireless Microphone Daktronics Inc. requests that the schematic diagram included as a requirement specified by Section 2.1033(b)(5) of FCC rules be withheld from public disclosure in accordance with Section 0.457 and 0.459 of the Commission’s Rules, 47 C.F.R., following grant of the FCC ID application. In support of this request, Daktronics submits the following: 1) Identification of the specific information for which confidential treatment is sought The HS-200 Wireless Microphone schematic diagram, included as a requirement for Section 2.1033(b)(5), is that for which confidentiality is sought. 2) Identification of the Commission proceeding in which the information was submitted or a description of the circumstances giving rise to the submission: The proceeding is that involving the application for equipment authorization (certification) and FCC ID number assigment for the HS-200 Wireless Microphone. 3) Explanation of the degree to which the information is commercial or financial, or contains a trade secret or is privileged: This schematic diagram includes the results of design and testing engineering effort that was sponsored by Daktronics, Inc, and is therefore is considered confidential. 4) Explanation of the degree to which the information concerns a service that is subject to competition: This product could possibly be used in a similar system designed by a scoring and timing or other Daktronics competitor. 5) Explanation of how disclosure of the information could result in substantial competitive harm: Disclosure of the schematic diagrams would in effect give away Daktronics intellectual property to competitors. This would give competitors an unfair advantage in the expenditure of engineering and other development cost, as well as time to market of a similar design.

Daktronics is committed to supporting its products for extended period of time. While design enhancements may be made during this time, a release of this material would reveal the knowledge gained as a result of Daktronics investment in hours of labor, engineering and other, and give competitors and unfair advantage as asserted in (5.) The release of this information would also violate company policy as asserted in (6.) Randy Uehran Product Engineer Daktronics Inc.

HS-200 Wireless Microphone Theory of Operation The HS-200 Wireless Microphone uses an OEM RF module and PCB mount antenna to transmit both voice and data signals to the HS-200 receiver. This device is used as a PA and starting system for swimming, track and other applications. A modified CB microphone controls the unit. When the side button on the microphone is pressed, a digital signal is sent to the receiver, turning the audio circuits on. Any voice picked up by the microphone while the side button is pressed is transmitted to the receiver. When the top button on the CB microphone is pressed, a digital signal is transmitted to the receiver, which produces an audible tone.
