This device is installed on-site by a professional field technician, thus it includes technical terms. The equipment is not to be installed by a non-professional individual. The information in this manual is provided only as instructions for installation and does not entitle user to make any modifications or adjustments. 1.2 System General Description The Speed Tx system is a computerized fully automatic radio device. It requires no human intervention after initial installation. The system enables remote, continuous and accurate reading of water consumption. The Speed Tx transmits the data acquired from water meters to a regional concentrator (directly or via a repeater). The concentrator transfers the data to the central computer for data collection and for further analysis and reporting. Note: 1) The system, including transmitters, transceivers and concentrators, is installed and maintained only by qualified professional technicians. 2) The device is not adjustable by user and is supplied by manufacturer ready for installation witout provisions for adjustmant. Speed Tx User Manual Miltel Communications Ltd.4 Chapter 2 Theory of Operation 2.1 General Description The Speed Tx is the first link in the water readings collection system. It is an independent unit that does not require an external power source, wiring, or the preparation of an infrastructure. The unit is installed in proximity to the water meter/s and is connected to several adjacent meters. Figure 2-1 (see next page) shows a typical installation of a Speed Tx unit, connected to several meters (of various types) at a single location. The unit can be connected to any type of meter which has a pulsed output (a passive magnetic open/short reed relay). The Speed Tx acquires the consumption data from the water meters and stores this data in its memory. The unit includes a miniature low-power RF transmitter which transmits data on a periodic basis to a regional concentrator (directly or through a relay station).

This device consists of two major sections, all using a common power source:
Digital section (Micro Controller)
RF section A 3.6 volts Lithium battery provides power to all parts of the device. The power supply for the RF section is controlled via the Tx switch (not shown), thus cutting of power to the transmitter unless necessary for actual data transmission (standby mode).

Speed TxRF Exposure 1 RF Exposure The total Effective Radiated Power of the Transmitter (E.U.T.) in mW can be calculate from the following equation: Where E is the electric field in μV/m at a distance R from the E.U.T.. 15.231(e) limit is 4400μμV/m at 3meter. Substituting the limit in the above equation: We get: ERP = 0.0058 mW The E.U.T. is not a portable or mobile unit, hence the limit of §1.1310 table 1 will apply: Limit(mW/cm 2 )=433.93/300=1.5 The E.U.T. ERP is very low i.e. 5.8 μWμ. Even if all the power will be directed through an area of 1cm 2 the outcome will be a significant margin below the limit: In reality the margin is even greater. Conclusion The E.U.T. complies with the radio-frequency exposure limits. ERPmw 4 π . R 2 . E 2 . 377 1000 . ERP 4 π . 3 2 . 4.4 10 3 . 2 . 377 1000 . Margin_dB 10 log 0.0058 1.5 . 24

The E.U.T. is a battery operated low-power Transmitter connected to meters (e.g. water). The device senses meter pulses and accumulates this data for transmission at a pre-defined time. When deployed, the Transmitter sends data directly to a Concentrator or via a Transceiver. For more details see the Block Diagram attached to form 731. Modifications to E.U.T.

Operation of E.U.T. Environmental Test Conditions The E.U.T. was tested at 28 0 C and 58% Humidity. A new battery was installed in the unit at the beginning of the tests (as per 15.31(e)). E.U.T. Operating Modes The E.U.T. has two modes: 1. Transmit 2. Standby between Transmissions. Although the Transmit mode is by far the worst condition for radiated emissions the Standby mode was also tested. E.U.T. Configuration and Peripherals Meter cables with magnetic switches where connected as this represents the worst case EMC conditions. The E.U.T. was initialized when the Test Port was short (see description) to allow the transmission of consecutive messages in order to measure the emissions with an automatic EMC receiver (spectrum analyzer).

Measurement Methods and Test Results 9.1 R a d i a t e d E m i s s i o n M e a s u r e m e n t R e s u l t s Measurement Method The tests were performed in Hermon Labs large full Anechoic Chamber (9m X 6.5m X 5.5m) with conductive floor (see drawing). The E.U.T. was placed on a wooden turntable. The Hydrolic antenna tower was moved such that the receive antenna was 3 meters from the EUT. The frequency range from 30MHz to 4.5GHz was investigated using an automatic HP8546A EMI receiver 9KHz – 6.5GHz and HP85460A RF filter section. The receive antenna height was changed from 1 to 4meters, polarization was changed from Vertical to Horizontal and the turntable was rotated 360 0 . The following table lists frequencies at which emissions were measured using an average detector (as per 2.231(b)(2)). Limits Limit for fundamental was used as per 15.231(e): 4400μμV/m or 72.8dB μV/m. Limits for spurious emissions were used as per 15.209 for restricted bands. For the other bands, 15.231(e) or 15.209 which ever is higher as per 15.231(b)(3). The E.U.T. was operating in the test mode, generating consecutive messages such that the average detector measured the peak power for the fundamental and harmonics. Note: Because the Transmission duration is more than 0.1Sec no averaging factor was used (as per 15.35). SignalFrequency (MHz) Measured max. Avrg.
