SAMSUNG Electronics CO., Ltd. (Maetan-dong) 129, Samsung-ro, Yeongtong-gu, Suwon-si, Gyeonggi-do, Republic of Korea June 22, 2020 Application Examiner / Reviewing Engineer Federal Communications Commission 7435 Oakland Mills Road Columbia, MD 21046 To Whom It May Concern, We are requesting special consideration for internal photos and user’s manual exhibits to be made post grant Long-Term Confidential for FCC ID: A3LRF4422D-D1A. The transmitter is a Base Station where access is controlled and only available to trained personnel. Please note that the internal photos are being asked to be confidential under the FCC guidelines that this is a non-consumer device (Base Station) and is inaccessible to the general public due to the location of the device and it is only serviceable by the licensee or his designated technicians. The user manual is being requested to be confidential under the FCC guidelines that the manual is very technical and is not provided to the general public. The user manual contains proprietary information required for trained installers to commission the base station. The user manual will be used by the licensee or his designated technicians only. Having the subject information easily available to competitors would negate the advantage we have achieved by developing this product. We are fully aware that the requested special condition for confidentiality for internal photos and user’s manual exhibits were publicly available for the period of time 10 months and that this information may still be publicly availed by other third party Web Sites not associated with the Federal Communications Commission.
