March 5, 2004 Applicant: Inovonics Wireless Corp. FCC ID: HCQ3B6FTSDTM Correspondence Reference Number: 26196 731 Confirmation Number: EA322700 Re: Action Items regarding Modular Approval 1) Compliance with Public Notice DA 00-1407. Public Notice DA 00-1407 contains guidelines and requirements for obtaining modular transmitter approval. The transmitter in question is a self-contained device having its own reference oscillator, permanently attached antenna, and RF shielding. The only external connections to the module are power and data. 1-1) This module contains shielding to mitigate RFI and does not rely upon external shielding from the device to which it is attached. 1-2) The data inputs are buffered by the micro-controller within the module. 1-3) This module is designed to operate from a 3V primary cell within the module. An internal voltage regulator provides a stable power supply to the VCO and PA driver stages. 1-4) The antenna is permanently affixed to the module, per 15.204. The Internal Photos Exhibit has been updated to designate the antenna structure. 1-5) The module was tested as a stand-alone device. 1-6) The module is labeled with the FCC ID. In addition, the products in which it is integrated are labeled with the FCC ID. 1-7) The module complies with all applicable FCC rules. No combination of input stimuli exist that could cause the module to operate in a manner that is not consistent with the rules. 1-8) The module complies with MPE requirements, as outlined in the MPE exhibit. 2) Show compliance with antenna requirements of 15.204. The antenna is permanently affixed to the module. The Internal Photos Exhibit has been updated to designate the antenna structure. 3) Upload any install instructions given to product integrators. This module was designed to meet the specifications of a single OEM customer. No installation instructions have been created. 4) Remove error from MPE exhibit. The MPE exhibit now contains the correct field strength limit of f/1500 and 30 minutes of averaging. 5) Indicate intended host products. This module was designed to mate to specific meter reading products, designated E2 and E4, designed and manufactured by Energy Billing Systems of Colorado Springs, Colorado.

FCC ID: HCQ3B6FTSDTM FA5253XS 5. ID Label/Location Info: Energy Billing Systems Phone-800-637-4242 FA5253XS FCC ID: HCQ3B6FTSDTM This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This label is printed on 2.5 inch by 1.0 inch clear label stock. Below are photos of the FCC label as it appears in a typical OEM application of the FA5253XS module. The photos below are of the back-side of the OEM device.

FCC ID: HCQ3B6FTSDTM FA5253XS 9. RF Exposure Information: Calculation for compliance with MPE requirements (47CFR2.1091) is done using a worst-case transmitter power of 250 mW, assumption of a unity gain antenna, and an exposure limit of 3 mW/cm 2 (f/300 mW/cm 2 at 20 cm per 47CFR1.1310) for general applications. This device is not carried or worn by the end user. It has an extremely low duty cycle and a low rate of transmission that dramatically reduces the average power level that could pose an exposure hazard. During operation the device transmits 12 packets once every four hours, however the averaging interval specified in 47CFR1.1310 is 6 minutes. Each transmitted packet contains a total of 213 RF pulses, each having a width of 20
s. Therefore the transmitter is on for 4.26 ms during each packet, and the worst-case power density assuming a 6-minute interval is, 226 6.70 )20(4 1 1060 min120213 min6 12 250 cm nW cmspulse s packet pulsespackets mW=¥ ¥ ¥¥¥¥ pm m This is well below the 3 mW/cm 2 limit.
