Schematic Diagram PCB Layout Block Diagram Operation Descriptions Tune-up Procedure Antenna Specification Parts list Above mentioned document contains detailed system and equipment description are considered as proprietary information in operation of the equipment. The public disclosure of above documents might be harmful to our company and would give competitor an unfair advantage in the market. In additional to 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 are requesting the commission to grant short-term confidentiality request on the following attachments until 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 correspondent during certification review process cannot be granted as confidential documents and those information will be available for public review once the grant of equipment authorization is issued. Sincerely Yours, Jacob Cho Director On behalf of LG Electronics Mobilecomm U.S.A., Inc.

※ FCC ID Label Form Note: The FCC ID shown will be readily visible at the time of purchase. Note! The label of the EUT is made of a white polypropylene laminate film and it's attached to the EUT by an adhesive. The adhesive is permanent type with strong strength. Additionally, the FCC ID is readily visible to the purchaser at the time of purchase because the phone will be marketed without the battery installed.
