Box 1086 El Granada, CA 94018 email: [email protected] ADDENDUM TO TEST REPORT RE: RF EXPOSURE Applicant: Sensus Metering Systems Inc. FCC ID: KCHMXU530T The EUT is a utility meter transmitter that transmits customer usage data when it is interrogated by a utility company truck-mounted transmitter. The EUT, when interrogated, will respond with a 72msec burst of data. These meters typically transmit 1-5 times per month, at most once per day. The time- averaged RF exposure levels are therefore extremely low. Per FCC’s Knowledge Data Per FCC’s Knowledge Data Base inquiry number 848176, for very low duty cycle utility meters, grant notes and user manual notes referencing MPE limits are not required.

The EUT was placed on a wooden table resting on a turntable on the test site. The search antenna was placed 3m from the EUT. The EUT antenna was positioned in the XY plane (“X-hat”), the first of three test positions. 2. The turntable was slowly rotated to locate the direction of maximum emission at each emission falling in the restricted bands of 15.205. 3. Radiated emissions were investigated for a LOW channel, a MID channel, and HIGH channel. Emissions were investigated to the 10 th harmonic. Sensus Metering Systems FCC ID: KCHMXU530T Report No. 06PR042FCCREP REV 1.1 Sensus 530-T Electric Meter Transceiver Module 5 of 43 900MHz DTS 4. Once maximum direction was determined, the search antenna was raised and lowered in both vertical and horizontal polarizations. The maximum readings so obtained are recorded in the data listed below. 5. Steps 2 - 5 were repeated for YZ (“Y-hat”) and XZ (“Z-hat”) orientation of the EUT. Test Results: Worst-case results are presented (Y-hat position). Refer to data sheets below. Restricted band emissions meet 54 dBuV/m. Other undesired emissions from the transmitter meet the -20 dBc requirement in 15.247(c), as follows: Maximum output power in 100kHz BW = 18.77 dBm (refer to spurious emission plots below) Calculated fundamental frequency field strength at 3m: 95.24 + P dBm + G, dBi = 95.24dB + 18.77dBm + 2.2dBi = 116.2 dBuV/m 116.2 dBuV/m – 20 dB = 96.2 dBuV/m limit for non-restricted band emissions outside 902-928 MHz operating frequency band. Non-restricted band emissions measured at more than 20 dB below limit, refer to data sheets below.
