August 21, 2006 Office of Engineering and Technology Federal Communications Commission Columbia, MD 21046 Applicant: Lectrosonics, Inc. 581 Laser Road Rio Rancho, NM 87124 Re: Confidentiality for submittal information regarding FCC ID number DBZSMV PRODUCT: Wireless Microphone transmitter operating under part 74. Dear Sirs: Lectrosonics, Inc. requests that the material in the Parts List, Block Diagram, Schematics, and Operational Description be withheld from public disclosure in accordance with Section 0.459 of the Commissions Rules, 47 C.F.R. 0.459 (1998), following grant of the application. In support of this request, Lectrosonics, Inc. submits the following: 1. Identification of the specific information for which confidential treatment is sought: The materials set fourth in the Operational Description, Parts List, and Schematics, which are segregated from the non-confidential exhibits of the application, are those 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) under FCC ID No: DBZSMV 3. Explanation of the degree to which the information is commercial or financial, or contains a trade secret or is privileged: This material includes a detailed theory of operation, circuit diagrams, (schematic diagrams) and detail Parts List. As such, this material is treated as highly confidential business information. ROGERS LABS, INC. 4405 West 259 th Terrace Louisburg, KS 66053 4. Explanation of the degree to which the information concerns a service that is subject to competition: The material for which confidentiality is sought is employed in the design and manufacture of this transmitting equipment that is offered on a highly competitive basis. Customers for this equipment have a variety of competing sources. 5. Explanation of how disclosure of the information could result in substantial competitive harm: Disclosure would, in effect, give away the fruits of the labors of Lectrosonics, Inc.’s engineering personnel, who have designed the equipment and the manufacturing process. Disclosure would also offer competitors additional unwarranted insight into the state of the product development, thereby allowing competitors an advantage, not available to Lectrosonics, Inc. 6. Identification of any measures taken by the submitting party to prevent unauthorized disclosure: The information for which confidential treatment is sought is kept confidential by Lectrosonics, Inc. and not made available to third parties except pursuant to non-disclosure agreements. 7. Identification of whether the information is available to the public and the extent of any previous disclosure of the information to third parties: To the knowledge of those preparing this application, the information has not been disclosed publicly heretofore. While the general theory of operation of this equipment has been the subject of numerous disclosures in industry and standards groups as well as in rule making proceedings of the FCC, the protection sought is narrowly drawn and pertains to certain specific implementations of this radio technology. 8. Justification of the period during which the submitting party asserts that the material should not be available for public disclosure: This material should not be disclosed for at least 25 years. While improvements in design are made relatively frequently, disclosure of the design information would lead to insights into both design and manufacturing techniques that could have an adverse competitive effect for many years to come. This equipment is designed for commercial, industrial, and governmental applications. As such, unlike most consumer equipment, this equipment could be used for more than a decade in some cases. As such, it is important that the design not be made available to unauthorized persons who might attempt to use knowledge of the design to compromise the applications for which the equipment will be employed. Should you require any further information, please contact the undersigned. Thank you for your consideration in this matter. Sincerely, Scot Rogers

October 9, 2006 Federal Communications Commission Equipment Approval Services P.O. Box 35815 Pittsburgh, PA 15251-3315 Applicant: Lectrosonics, Inc. 581 Laser Road Rio Rancho, NM 87124 Re: Response to Correspondence reference number 31760 Equipment: FCC ID: DBZSMV, 731-confirmation number EA460316 Gentlemen: A portion of the correspondence requesting additional information is shown below for reference. The response to this request is addressed below for your consideration. Request Regarding compliance with FCC RF exposure requirements, MPE estimation is submitted in this filing. FCC RF exposure limits for devices operating closer than 20 cm to persons are in terms of SAR, therefore MPE estimation is not applicable for compliance demonstration of portable devices. To support FCC RF exposure compliance determination, please submit photos and/or sketches for product with antenna installed showing spacings between the plane of the back of the belt- clip to: a) the back of the device, b) the closest point(s) of installed-antenna(s) FCC will then review all filing info to determine whether other info may need to be requested to support compliance with RF exposure requirements as applicable for all transmitters regulated by FCC. It may help to expedite this review if applicant has available and wishes to voluntarily submit SAR test results for this specific product. Response Below please find relevant photographs per your request demonstrating spacing between the back of the device and antenna, and the back of the clip and antenna. Photograph showing separation distance from the back of equipment to the antenna. Photographs showing separation distance from back of equipment and back of belt clip to antenna. Additional discussion From our understanding of CFR47 requirements as discussed below, it appears this equipment is categorically excluded from the SARS requirement. CFR47 1.1307(b)(1) suggests: "... transmitters that fall into the categories listed in table 1, or those specified in paragraph (b)(2) of this section." In table 1 the entry for part 74 services, references evaluation is required only for Subparts A, G, L (power > 100 W ERP), and Subpart I antennas (power > 1640 W EIRP). However, Subpart H governs this equipment. In paragraph (b)(2), references equipment covered under Subpart H of parts 22, 24, 25, 26, 27, 80, and 90 but NOT part 74. The paragraph ends with the declaration: "All other mobile, portable, and unlicensed transmitting devices are categorically excluded from routine environmental evaluation for RF exposure under SS 2.1091, 2.1093 of this chapter except as specified in paragraphs (c) and (d) of this section." Paragraph (d) maintains the statement to the effect that if the Bureau responsible for processing an action that is categorically excluded happens to think that the proposal may result in significant environmental impact, then it may require evaluation "on its own motion". However, for our own assurance that it complies with SARS requirements, we did have a 250 milli-Watt transmitter tested for SARS compliance in the higher frequency bands. The SAR data taken for the SMQ device represents the worst-case configuration for this type of body worn equipment with respect to spacing, power level, and frequencies of operation. Correspondence with the SAR testing facility indicated testing of the equipment in the higher frequency typically produced the worst case SAR data and demonstrates compliance for lower frequencies of operation. Therefore, only the higher frequency units were tested for SARS compliance. Please find the SAR test report attached for your review. The report demonstrates compliance for occupational use. The SMV transmitter yields lower output power than the unit used for SAR testing but maintains identical separation distances. Please review this information and continue processing the application for grant of certification. Should you require any further information, please contact the undersigned. Thank you for your consideration in this matter. Sincerely, Scot Rogers Rogers Labs, Inc. Enclosures

Validation Dipole Construction & Electrical Characteristics The validation dipole was constructed in accordance with the IEEE Standard “Annex G (informative) Reference dipoles for use in system validation”. The electrical properties were measured using an HP 8753ET Network Analyzer. The network analyzer was calibrated to the validation dipole N-type connector feed point using an HP85032E Type N calibration kit. The dipole was placed parallel to a planar phantom at a separation distance of 15.0mm from the simulating fluid using a loss-less dielectric spacer. The measured input impedance is: Feed point impedance at 835MHz Re{Z} = 47.627: Im{Z} = -0.67188: Return Loss at 835MHz -31.954dB 835 MHz System Validation Dipole (Body) 2005 Celltech Labs Inc. 3 of 12 2.

Validation Phantom The validation phantom is the SAM (Specific Anthropomorphic Mannequin) phantom manufactured by Schmid & Partner Engineering AG. The SAM phantom is a Fiberglass shell integrated in a wooden table. The shape of the shell corresponds to the phantom defined by SCC34-SC2. It enables the dosimetric evaluation of left and right hand phone usage as well as body mounted usage at the flat phantom region. A cover prevents evaporation of the liquid. Reference markings on the phantom allow the complete setup of all predefined phantom positions and measurement grids by manually teaching three points in the robot.

SAR Measurement The SAR measurement was performed with the E-field probe in mechanical detection mode only. The setup and determination of the forward power into the dipole was performed using the following procedures. PM1 Att1 x Dipole 3D Probe positioner Flat Phantom Field probe Signal Generator AmpLow Pass 3dB Att3 Dir.Coupler Att2 PM2 Cable PM3 d First the power meter PM1 (including attenuator Att1) is connected to the cable to measure the forward power at the location of the dipole connector (X). The signal generator is adjusted for the desired forward power at the dipole connector (taking into account the attenuation of Att1) as read by power meter PM2. After connecting the cable to the dipole, the signal generator is readjusted for the same reading at power meter PM2. If the signal generator does not allow adjustment in 0.01dB steps, the remaining difference at PM2 must be taken into consideration. PM3 records the reflected power from the dipole to ensure that the value is not changed from the previous value.
