Model: USBXCVR2 RF Exposure Model: USBXCVR2 FCC ID: SDBUSBXCVR2 IC: 2220A-USBXCVR2 ACS Project: 13-2054 Advanced Compliance Solutions Page 2 General Information: Applicant: Sensus Metering Systems, Inc. ACS Project: 13-2054 Device Category: Mobile (Handheld) Environment: General Population/Uncontrolled Exposure Technical Information: Antenna Type: Monopole Antenna Gain: -1 dBi Maximum Transmitter Conducted Power: 20.16 dBm, 103.75 mW Maximum System EIRP: 19.16 dBm, 82.414 mW Exposure Conditions: Greater than 20 centimeters Justification for Exclusion The Sensus USB Flexnet Micro-Transceiver (FMT), Model USBXCVR2, is a 900 MHz – 960 MHz transceiver which connects to a laptop, handheld PC or other USB 2.0 host (Master) device using a regular USB receptacle connector. The unit is used to configure Flexnet radio modules. Per the device typical operation and the customer appended justification, the minimum test distance is obtained when the unit is used in the handheld PC configuration. The SAR exclusion can be determined using the parameters below based on the client appended justification: Minimum Test Distance : 40 mm Maximum Duty Cycle : 24.37% Highest Operating Frequency: 960 MHz Average Maximum Power: 103.75 mW * 24.37 / 100 = 25.285 mW Per KDB 447498 D01 General RF Exposure Guidance v05r01, the 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] · [√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR = (25.285 / 40)*( √0.960) = 0.632 * 0.98 = 0.6 Based on the results above, the unit meets both body and extremities SAR exclusion requirements.

Bowman Drive Buford, GA 30518 Re: SAR Requirements for the USB FMT (USBXCVR2) FCC ID: SDBUSBXCVR2 Device Description The USB FMT is a radio module interrogation device connected via USB to either a third party handheld PC or laptop. It is used to install and configure FlexNet radio modules. The USB FMT has one radio that can be employed in two different modes, a long range mode (2-FSK) or a short range mode (ASK). Operating Modes The USB FMT is capable of the following transmissions and types: 5kb/s 2-FSK (5K90F1D), Po=20dBm, 896 to 960MHz 10kb/s 2-FSK (11K8F1D), Po=20dBm, 896 to 960MHz 12.5kb/s 2-FSK (14K8F1D), Po=20dBm, 896 to 960MHz 2700b/s ASK (10K30F2D), Po=14dBm, 896 to 960MHz Typical Use The USB FMT is typically used either with a handheld PC running an application called Field Logic for Flexnet radio installation and configuration or with a laptop running a utility called FlexNet Utility for Flexnet radio diagnostics. It can be shown in both cases that the recommended installation of the USB FMT provides ample distance to the body. In both cases, the distance from the antenna to the body is greater than 14mm which is the minimum distance allowed by Section 4.3.1, Paragraph 1 of General RF Exposure Guidance v05r01 document from the FCC OET based on a worse case frequency of 960MHz and 20 dBm output power. For the handheld PC, it is recommended by Sensus that the FMT be attached to the rear cover of the handheld as shown in the picture below. The typical distance between the hand and the USB FMT is 40mm. For the laptop, it is recommended by Sensus to attach the USB FMT to the exterior of the display as shown. The typical distance between the USB FMT and the hand is 150mm. Duty Cycle 1) FMT TX 90 bytes (This is the ON TIME for the FMT) = 144ms 2) End Point receives this data and delays 200ms before transmitting back 3) End Point TX 90 bytes of data back to FMT = 144ms 4) FMT sends 71 bytes at 9600 baud of data to Field Logic = 60ms 5) Field Logic sends 51 bytes at 9600 baud of data back to FMT to start a new TX packet = 43ms So a FMT Transmitted packet of data would take: 144ms + 200ms + 144ms + 60ms + 43ms = 591ms The duty cycle of the FMT TRANSMIT TIME of 144ms per packet would be 144ms / 591ms = 24.37% Sincerely, Al Servais | Reliability and Compliance Program Manager 639 Davis Drive | Morrisville, NC 27560 USA T: 919-317-6351 | C: 919-208-8983 | [email protected] | www.sensus.com

The FMT operates in slave (peripheral) mode and is used within the Sensus FlexNet System in conjunction with the Sensus Buddy Monitor software to remotely communicate to FlexNet SmartPoint devices and send setup or status commands to the SmartPoint devices. Manufacturer Information: Sensus Metering Systems, Inc. 639 Davis Drive Morrisville, NC 27560 Test Sample Serial Numbers: Radiated: 6265 (TXC); RF Conducted: 6266 (TXC), 6277 (Rakon) Firmware Revision: B2.2.1.3 on 4/17/13 Hardware Revision: Rev 4.1 on 5/10/13 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 Sensus Model USBXCVR2 includes two model variants consisting of different TCXOs (TXC and Rakon). Preliminary evaluations were performed for both TCXO model variants for both radiated and RF conducted emissions. The data provided herein consists of the worst case. For the radiated emissions evaluation, additional preliminary measurements were performed for the EUT set in three orthogonal orientations as compared to the ground plane. The test reports document the worst case orientation and data rate. For the RF conducted measurements the unit was modified with a temporary 50 ohm connector at the antenna port. The unit was evaluated for all available modulations and where applicable the worst case is provided. Evaluation for unintentional emission is documented separately in a DOC/Verification test report.
