5015 B. U. Bowman Dr. Buford, GA 30518 February 8, 2012 ACS TCB 5015 B.U. Bowman Drive Buford, GA 30518 Re: FCC ID: SDBIDTB003 To Whom It May Concern: The following application is submitted on behalf of our client, Sensus Metering Systems, Inc., for evaluation of their model IDTB003 for certification under FCC Part 24 Subpart D and Part 101 Subpart C. The IDTB003 is a stand-alone module consisting of a single printed circuit board which is designed to be integrated into specific host devices. The IDTB003 monitors meter reading and diagnostic information. The device communicates via the Sensus USA Inc. fixed wireless telemetry network to provide electric meter readings and diagnostic data from the meter to the utility provider via a two-way radio link. The IDTB003 was tested in full to the requirements of the aforementioned rules and was found to be in compliance. Even though some exhibits refer to a Zigbee module, the IDTB003 is not co-located with this module for this filing. In the future, the IDTB003 will be co-located with the Zigbee module and a C2PC will be filed at that time. Sincerely, Sam Wismer Vice President, Technology Advanced Compliance Solutions, Inc.

The Sensus FlexNet Transceiver is professionally installed within various Sensus host devices (See Appendix 2). The module label will be located in a visible area on the host and will display all necessary and pertinent information about the modular device. 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, professionally installed, and is only serviceable by Sensus, or designated technicians. The modular device lies beneath multiple layers of poly carbonate that are mounted a steel meter pan and the device is either collar locked or ring locked according to the utility process for security of metering devices. The assembly hardware is sealed with looping wire that is crimped and sealed. These mechanisms along with the alarm features make it near impossible for any person to try and make contact with the modular device. Please feel free to contact me directly should there be any questions regarding this matter .

The device acts as the “Integrated Communications Device”. The IDTB003 provides the RF functionality for the meter and contains the meter display circuitry. The IDTB003 monitors meter reading and diagnostic information via an SPI serial interface supplied by the Sensus Sensor Board. Interconnection between the two boards is accomplished using a multi- conductor flexible cable. The device communicates via the Sensus USA Inc. fixed wireless telemetry network to provide electric meter readings and diagnostic data from the meter to the utility provider via a two-way radio link. Manufacturer Information: Sensus Metering Systems, Inc. 639 Davis Drive Morrisville, NC 27560 Test Sample Serial Numbers: TB04, TB05 and TB06 Test Sample Condition: The unit was in good operating conditions with no physical damages. 1.3 Test Methodology 1.3.1 Configurations and Justification The IDTB003 was evaluated for radiated emissions and RF conducted measurements. The radiated emissions investigation was performed up to the 10th harmonic with the EUT standalone while set in the orientation of typical operation. A unit with a temporary SMA connector was provided for the RF evaluation at the antenna port. The evaluation for unintentional emission is documented separately in a verification report.
