Page 1 of 1 Request for Confidentiality Date: May 1, 2026 Subject: Confidentiality Request for: FCC ID: 2A29A-FBXDC IC: 27842-FBXDC Pursuant to FCC 47 CFR 0.457(d) and 0.459 and IC RSP-100, Section 12.4, the applicant requests that a part of the subject FCC application be held confidential. Type of Confidentiality Requested Exhibit ☐ Short Term ☒ Permanent ☐ Not Provided Block Diagrams ☒ Short Term ☐ Not Provided External Photos ☒ Short Term ☐ Permanent ☐ Not Provided Internal Photos ☐ Short Term ☒ Permanent ☐ Not Provided Operation Description/Theory of Operation ☐ Short Term ☐ Permanent ☒ Not Provided Parts List & Placement/BOM ☐ Short Term ☐ Permanent ☒ Not Provided Tune-Up Procedure ☐ Short Term ☒ Permanent ☐ Not Provided Schematics ☒ Short Term ☐ Not Provided Test Setup Photos ☒ Short Term ☐ Permanent ☐ Not Provided User’s Manual The above-mentioned company has spent substantial effort in developing this product and it is one of the first of its kind in industry. Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship. Permanent Confidentiality: The applicant requests the exhibits listed above as permanently confidential be permanently withheld from public review due to materials that contain trade secrets and proprietary information not customarily released to the public. Short-Term Confidentiality (if applicable): The applicant requests the exhibits selected above as short term confidential be withheld from public view for a period of 180 days from the date of the Grant of Equipment Authorization and prior to marketing. This is to avoid premature release of sensitive information prior to marketing or release of the product to the public. Applicant is also aware that they are responsible to notify Timco in the event information regarding the product or the product is made available to the public before the requested period has expired. Timco will then release the documents listed above for public disclosure pursuant to FCC Public Notice DA 04- 1705.
