RE: Request of Long-Term Confidentiality for FCC ID: A3LRF4437D-25D

To Whom It May Concern:

This is a request to hold the internal photos and user manual for FCC ID: A3LRF4437D-25D under long

term confidentiality. 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.

The requested Long-Term Confidential exhibits are list as follows:
