Merchandize Mart Plaza, Chicago Il US www.motorola.com Date: December 4, 2025 Federal Communications Commission Office of Engineering and Technology Laboratory Division 7435 Oakland Mills Rd Columbia MD 21046-1609 Subject: Request for Confidentiality FCC ID: IHDT6AB7 To Whom It May Concern, Pursuant to the provisions of Sections 0.457 and 0.459 of Commission’s rules (47 CFR §§ 0.457, 0.459), we are requesting confidentiality for exhibits filed with the commission supporting the application of equipment authorization for those items referenced above. Motorola Mobility respectfully requests the Commission to withhold indefinitely from public disclosure the following attachments under Long-Term Confidentiality. ⚫ Schematic Diagrams ⚫ Block Diagrams ⚫ Operational Description ⚫ Tune-up Procedure The above listed documents contain detailed system and equipment descriptions that are proprietary and confidential information under Motorola trade secret protection. Public disclosure of above documents would be harmful to our company and would provide competitors an unfair advantage. This information is not made publicly available even after commercial release of the device. In additional to the above-mentioned documents, pursuant to Public Notice DA 04-1705 of the Commission’ s policy, in order to comply with the marketing regulations in 47 CFR §2.803 and the importation rules in 47 CFR §2.1204, while ensuring that business sensitive information remains confidential until the actual marketing of newly authorized devices. We request the commission to grant short-term confidentiality request on the following attachments for 180 days after the grant as outlined in Public Notice DA 04-1705. ⚫ External Photos ⚫ Internal Photos ⚫ Test Setup Photos ⚫ User Manual It is our understanding that all measurement test reports, FCC ID label format and correspondence during certification review process cannot be granted as confidential documents and that information will be available for public review once the grant of equipment authorization is issued.
