Aclara Technologies LLC Former HEXAGRAM Inc. 30400 Solon Road . Solon, OH 44139 440-528-7200 05/15/2012 LLB10004X2 RF Exposure calculations Based on FCC 1.1307 & 2.1091, FCC OET Bulletin 65. (1) Categorically Exclusion from RF exposure Evaluation: According to FCC regulations, RF exposure evaluation is Categorically Excluded if transmitter’s operation frequency is less than 1.5 GHz and ERP is less than 1.5 watt. (2) Absolute Maximum specifications of LLB10004X2 transmitter • Operational frequency band 450 MHz to 470 MHz. • The LLB10004X2 transmitter is measured for Max RF Power = 0.661 W. • Absolute Maximum transmission time (duration) for any Hexagram transmitters does not exceed 100 mS (0.10second). • Transmission period – Absolute maximum is 4 transmissions per hour. • All Hexagram Transmitters utilize FSK modulation. (3) Average RF Power Calculation: FCC regulations on permissible RF exposure are not based on peak envelope power (PEP), but on average power (P_ave) over a 30-minute time period for uncontrolled environments. As mentioned in (2), during any 30 minute Hexagram MTU can transmit only two times. Duration = 0.10 second. With maximum RF radiation equal to 0.661 W, the Average RF Power over 30 minutes is: P_ave (worst case) at 30 minute = 0.661W*30* [0.10sec/((30*60)sec)] = 0.661*30* 0.000055 = 1.1mW (4) Maximum Radiated Power Density prediction (S): To predict power density (S) at distance R=20 cm from transmitter with P_ave = 0.00007W, next formula is used: S = P_ave/(4*(PI)*R^2) For the worst of the worst worst-case prediction of power density at or near a transmitter surface let’s use: S = P_ave/((PI)*R^2) = 1.1 mW/(4*3.14*20cm*20cm) = 0.217uW/cm^2. This is the worst case of the near field power density of LLB10004X2 transmitter. (5) Maximum Permissible Exposure (MPE): AS FCC require, the maximum permissible exposure for general public in “uncontrolled situation” at 20 cm is: MPE = 460MHz/1500 = 1.228 mW/cm^2. By comparing results in (4) and (5), S=0.217uW/cm^2 < MPE=1.228 mW/cm^2. We see that LLB10004X2 fully complies with RF safety at a distance of 20 cm.

James R. Pollock 30400 Solon Road Solon Ohio 44139 (440)528-7200 ENGINEERING TEST REPORT RADIO-FREQUENCY EMISSIONS TEST REPORT FOR HIGH READ-RATE GAS METER TRANSMITTING UNIT Model 2010-004X2 FCC ID: LLB10004X2 May 4, 2012 Report Prepared by Agency Certification Control Technician ACLARA TECHNOLOGIES LLC LLB10004X2 2 TEST REPORT INTRODUCTION The Aclara Model 2010-004X2 transceiver is a “Meter Transmitting Unit” (MTU) designed to provide remote meter reading capability for a gas meter. The transceiver is self- powered and mounts directly on a gas meter. On board batteries provide power. The transmitter provides a very short, intermittent radio frequency transmission to send a remote reading of the meter to a data collector unit. A microprocessor provides timing, control and data processing functions. The internal antenna is inaccessible to the user and no external antenna is provided. Two prototype units were used as a test subjects for this report. The unit used for each test is identified under the test procedure. This report presents the data obtained in support of an application for Certification under Part 90 of the FCC rules and RSS-119-iss11 of Industry Canada. MEASUREMENTS PERFORMED Low Frequency Emissions Page 3 Power Output and Spurious Emissions Page 4 with test set up photographs Occupied Bandwidth Page 11 Frequency Stability vs. Temperature Page 13 Frequency Stability vs. Supply Voltage Page 14 Transient Stability Page 16 Test Information Page 20 LLB10004X2 3 LOW FREQUENCY EMISSIONS Low frequency emissions were examined from 9 kHz to 330 MHz using an active loop antenna and a biconical antenna. Non-harmonic emissions above 330 MHz to 1000 MHz were determined with tuned dipoles. All emissions observed between 9 kHz and 1 GHz, other than the harmonics of the transmitter were determined to be more than 20 dB below the limit levels for spurious emissions of Part 90.210 and RSS-119.

All measurements below 1 GHz were made at a 3-meter distance on the Smith Electronics open area test site located at 8200 Snowville Road, Brecksville, OH. Data pertinent to this site is on file with the FCC (Reg. #90938) and Industry Canada (Site# 4541A-1). The harmonic measurements above 1 GHz were made at a distance of 1 meter over a suitable ground plane. The measurements were made using the substitution method described in TIA/EIA-603-C. Tuned dipoles were used for measurements below 1000 MHz and a wave-guide antenna was used above 1000 MHz. A spectrum analyzer was used as a receiver. The transmitter was placed on a remotely rotatable, non-conducting test stand. This general set up is shown in Pictorial 1. Because of the intermittent nature of the normally operating transmitter, the transmitter was forced to transmit continuously with a 30 seconds on and 30 seconds off cycle for these measurements. Power to the meter necessary to sustain the transmission was provided by an external 6 V battery. With the transmitter powered and the test receiver tuned to the unmodulated signal, the transmitter under test was rotated to the position of maximum signal. The receiving antenna was then varied between 1 and 4 meters in height to again maximize the signal. Measurements were made with the antennas positioned both vertically and horizontally and the maximum signals recorded. Peak detection was used for the signals below 1000 MHz and average detection above 1000 MHz. After the maximum received meter readings were obtained for each frequency and polarity, the transmitter under test was removed from the area and replaced by a signal generator and transmitting antenna. With the transmit antenna placed as close as possible to the position of the test unit, the signal generator was activated at a test frequency. With the signal detected, the receiving antenna was positioned for maximum reception. The signal generator output was then adjusted until the received signal was equal to the previously received signal from the unit under test. These measurements were repeated for each frequency and antenna orientation and the maximum values obtained are noted in Tables 1a – 1c. In order to convert the signal generator output value to equivalent radiated power from a dipole, the following equation is used: P d = P g – cable loss(dB) + antenna gain(dB d ) where: P d is the dipole equivalent power in dBm, P g is the generator output into the substitution antenna, also in dBm, and “antenna gain” is the dB gain of the substitution antenna with respect to a theoretical dipole. According to 90.210(d)(3) all emissions greater than 12.5 kHz from the center of the authorized band shall be attenuated below the unmodulated carrier by 50 + 10log(P). The determined power outputs, the required harmonic attenuation as well as the attenuation for each harmonic are found in Tables 1a – 1c.
