This is a request to hold the user manual for FCC ID: A3LRFV01U-D1Aunder long term confidentiality. The transmitter is a Base Station where access is controlled and only available to trained personnel.

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. All sales of the non-consumer device will be under NDA to include 3rd party sales and that the final user of the device is subject to the NDA as required by the special conditions of section II)3)c) of KDB 726920 D01.
