June 6, 2006 Timco Engineering Inc. 849 NW State Road 45 Newberry, FL 32669 Federal Communications Commission Equipment Approval Services P.O. Box 35815 Pittsburgh, PA 15251-3315 Applicant: Garmin International, Inc. 1200 East 151st Street Olathe, KS 66062 CORES number: 0005-0885-88 Re: Short-term and permanent Confidentiality for submittal information regarding FCC ID number IPH-00991 PRODUCT: Marine Radar operated under part 80. Dear Sirs: Short-term Pursuant to DA 04-1705 of the Commission’s pubic notice, we request short-term confidential treatment for the following information until 45 days after the Grant Date of Equipment Authorization in order to ensure sensitive business information remains confidential until the actual marketing of the device: External Photos Internal Photos Test Setup Photos User Manual Permanent Garmin International, Inc. also requests that the material in the Schematics, Operational Description, Parts list and Block diagram be withheld from public disclosure in accordance with Section 0.459 of the Commissions Rules, 47 C.F.R. 0.459, following grant of the application. In support of this request, Garmin International, Inc. submits the following information. 1. Identification of the specific information for which confidential treatment is sought: The materials set fourth in the Operational Description, Schematics, Parts list, and block diagram, which are segregated from the non-confidential exhibits of the application, are those for which confidentiality is sought. ROGERS LABS, INC. 4405 West 259 th Terrace Louisburg, KS 66053 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: IPH-00991 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, confidential Parts list, and schematics. As such, this material is treated as highly confidential business information and not available as general information. 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 Garmin International, 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 Garmin International, 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 Garmin International, 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

No reduction of heater voltage is required at any value of mean input power. For optimum performance a value within the specified ratings must be maintained. The magnetron heater must be protected against arcing by the use of a minimum capacitance of 4000 pF shunted across the heater directly at the input terminals; in some cases a capacitance as high as 2mF may be necessary depending on the equipment design. For further details see the Magnetron Preamble. 2. Measured with heater voltage of 6.3 V and no anode input power, the heater current limits are 0.5 A minimum, 0.6 A maximum. 3. For ambient temperatures above 08C. For ambient temperatures between 0 and7558C, cathode pre-heating time is 75 seconds minimum. 4. Design test only. The maximum frequency change with anode temperature change (after warming) is 70.25 MHz/8C. 5. The various parameters are related by the following formula: Pi = i apk xv apk xDu where Pi = mean input power in watts i apk = peak anode current in amperes v apk = peak anode voltage in volts and Du = duty cycle. 6. Defined as the steepest tangent to the leading edge of the voltage pulse above 80% amplitude. Any capacitance in the viewing system must not exceed 6.0 pF. 7. The maximum rate of rise of voltage for stable operation depends upon detailed characteristics of the applied pulse and the pulser design. The specified maximum rating applies to typ…

Per 2.1091(c) of CFR 47, the equipment is categorically excluded from routine environmental evaluation for RF exposure prior to equipment authorization or use. The radiating structure for the device is typically mounted more than 265 centimeters away and located outside the crafts helm. Due to the location of the antenna, normal operating conditions, and use the unit will satisfy the requirements for RF Exposure per CFR rule 1.1311. MPE calculations are shown below demonstrating compliance. ROGERS LABS, INC.
