AAO1501214RF Modulator

FCC ID: AAO1501214 Dear Sir, This is to request confidentiality on information submitted for above application. We would like to request confidentiality on some exhibits we submitted for above application for the reason of trade secret. If those exhibits are available for public inspection, any person who once gets the information contained in those exhibits will be able to design and to make the same products very easily. This is a very serious problem and huge loss for us, because we did invest so much on it. Please be not made the Exhibit Types listed below routinely available for public inspection: Block Diagram and Schematics.

Please find my explanation below: Question #1: Page 7 of test report which indicated 15.249 test procedures and requirement. This subject device is a TV interface devic under Part 15 Subpart B of FCC rule. Please make a necessary correction. ANS.: Sorry for the omission. Attached please find the corrected page. Question #2: There is no test data provided for antenna transfer switch measurement. Please provide it. ANS.: Sorry for our omission, this should be the format tansfer error. Please check attached page for this data. Question #3: There is no test data provided for output signal level measurement as required by 15.115(b)(1). Please provide it. ANS.: Please check page 17 of our test report, there is indeed the data for output signal level. If you have any further questions, please kindly infrom us. Regards, K. C.
