The Sensus TGB20 Transceiver is professionally installed. The regulatory label will be located on the rear of the enclosure and will display both the FCC ID of the TGB20. Confidentiality of the internal photos and the technical manual is being requested because this is a non-consumer device which is not accessible by the general public (See Appendix 2), which is professionally installed, and is only serviceable by Sensus, or designated technicians. When installed, the Sensus TGB20 cannot be accessed by anyone other than Sensus staff or designated technicians simply because the product is located within and enclosure that is key-locked within a utility or Sensus owned and access controlled area. Please feel free to contact me directly should there be any questions regarding this matter .

The device receives telemetry transmission from multiple system end point units used mostly for utility metering. The TGB20 sends also command information to the end point units. The TGB20 transceiver is housed in a rack mountable enclosure and is powered by 24 VDC. Manufacturer Information: Sensus Metering Systems, Inc. 400 Perimeter Park Drive, Suite K Morrisville, NC 27560 Test Sample Serial Numbers: 2078 Test Sample Condition: TheTGB20 was in good physical condition with no noticeable damages. 1.3 Test Methodology 1.3.1 Configurations and Justification The TGB20 was evaluated for compliance to the radiated and RF conducted emissions requirements. The radiated spurious emissions were evaluated up to the 10 th harmonic. The EUT was tested in the MPass (5k) mode. Compliance to the radiated and power line conducted emissions requirements are documented separately in a Verification Report. 1.3.2 In-Band Testing Methodology The EUT is designed to operate in multiple bands under the requirements of CFR 47 Parts 24 and 101. The following is a list of the frequency bands of operation sorted based on the FCC rule parts in which the band is associated.
