® Mini-MT Operational Description Information in this document is proprietary to Enfora, Inc. Page 1 of 1 The Mini-MT (GSM2228) is a portable hand-held tracking device utilizing GPS for location and GSM/GPRS/SMS for communication and configuration. See Figure 1 for a block diagram of the Mini-MT. The MLG0208 is a quad-band GSM/GPRS module with an integrated GPS receiver. The GSM and GPS antennas are integrated on the PCB. The SIM card is accessed in the battery compartment. The module also controls the CALL LED for display of call and registration status. Inputs from a user are through four (4) switches for volume up, down, user defined 1, and user defined 2. Audio interfaces include an internal microphone and speaker as well as a 2.5mm Audio jack for an external headset. A mini-USB connector and USB interface for data communications, product configuration, and charging the internal battery. The internal battery is the primary power source for the Mini-MT. The battery charger requires 5VDC +/- 0.25VDC at 500mA maximum.

MLG0208 Circuit Description Enfora, L.P. 661 E. 18 th Street Plano, TX 75074-5601 (972) 633-4400 Fax (972) 633-4444 MLG0208 Circuit Description General Description The MLG0208 Module utilizes a Silicon Laboratories Si4210 Transceiver. This transceiver is highly integrated and provides virtually all modem functions. The module (optionally) also contains a Global Locate GL-LN22 Integrated Front-End and GL-B32-TL GPS Baseband Processor. The modem’s baseband digital processor interfaces to the GPS baseband processor via a 4-wire μWire connection. GSM/GPRS Section Si4210 Transceiver The Si4210 provide the complete RF front-end for the GSM/GPRS functions. The receiver section interfaces between the RF band-select SAW filters and the baseband subsystem. The receiver uses a digital low-IF architecture. The transmit section provides upconversion path from the baseband subsystem to the power amplifier using an offset phase-locked loop (OPLL). The transceiver uses a digitally controlled crystal (26 MHz) oscillator (DCXO) that integrates the reference oscillator and varactor functionality. D751992AZPHR Digital Baseband Processor Provides digital interfaces and control of the system. It is operated from the main oscillator from the Si4210 and also has a real time clock crystal (32.768 kHz). GPS Section A two-chip GPS solution (front-end plus baseband processor) is operated from a 26 MHz TCXO allowing for autonomous operation when the GSM section is off. The front-end is fed from the antenna input through an LNA and band-pass filter. The front-end and the GPS processor interface digitally.

Transceiver Adjustments / Tune-Up Procedure There are no user accessible adjustments or tuning in this portable cellular transceiver. All necessary adjustments and tuning are performed during manufacture of the product. Any adjustments or tuning after service or repair are done as part of that process as special equipment is required to perform such adjustments.

DASY4 System Details A.7.1. DASY4 SAR Measurement System RFI Global Services Ltd, SAR measurement facility utilises the Dosimetric Assessment System (DASY™) manufactured by Schmid & Partner Engineering AG (SPEAG™) of Zurich, Switzerland. The DASY4 system is comprised of the robot controller, computer, near-field probe, probe alignment sensor, and the SAM phantom containing brain or muscle equivalent material. The robot is a six-axis industrial robot performing precise movements to position the probe to the location (points) of maximum electromagnetic field (EMF). A cell controller system contains the power supply, robot controller; teach pendant (Joystick), and remote control. This is used to drive the robot motors. The Staubli robot is connected to the cell controller to allow software manipulation of the robot. The data acquisition electronics (DAE) performs signal amplification, signal multiplexing, AD-conversion, offset measurements, mechanical surface detection, collision detection etc. The DAE is connected to the Electro-optical coupler (EOC). The EOC performs the conversion from the optical into digital electric signal of the DAE and transfers data to the PC plug-in card. The DAE3 utilises a highly sensitive electrometer-grade preamplifier with auto-zeroing, a channel and gain-switching mulitplexer, a fast 16-bit AD-converter and a command decoder and control logic unit. Transmission to the PC-card is accomplished through an optical downlink for data and status information and an optical uplink for commands and clock lines. The mechanical probe-mounting device includes two different sensor systems for frontal and sidewise probe contacts. They are also used for mechanical surface detection and probe collision detection. The robot uses its own controller with a built in VME-bus computer.

Measurement Methods A.2.1. Evaluation Procedure The Specific Absorption Rate (SAR) evaluation was performed in the following manner: a) (i) The evaluation was performed in an applicable area of the phantom depending on the type of device being tested. For devices worn about the ear during normal operation, both the left and right ear positions were evaluated at the centre frequency of the band at maximum power. The side, which produced the greatest SAR, determined which side of the phantom would be used for the entire evaluation. The positioning of the head worn device relative to the phantom was dictated by the test specification identified in section 3.1 of this report. (ii) For body worn devices or devices which can be operated within 20 cm of the body, the flat section of the phantom was used. The type of device being evaluated dictated the distance of the EUT to the outer surface of the phantom flat section. b) The SAR was determined by a pre-defined procedure within the DASY4 software. The exposed region of the phantom was scanned near the inner surface with a grid spacing of 20mm x 20mm or appropriate resolution. c) A 7x7x7 matrix was performed around the greatest spatial SAR distribution found during the area scan of the applicable exposed region. SAR values were then calculated using a 3-D spline interpolation algorithm and averaged over spatial volumes of 1 and 10 grams. d) If the EUT had any appreciable drift over the course of the evaluation, then the EUT was re-evaluated. Any unusual anomalies over the course of the test also warranted a re-evaluation.

Specific Absorption Rate (SAR) Measurements to OET Bulletin 65 Supplement C: (2001-01) Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields SAR measurements were performed in accordance with Appendix D of the standard FCC OET Bulletin 65 Supplement C: 2001, against appropriate limits for each measurement position in accordance with the standard. The test was performed in a shielded enclosure with the temperature controlled to remain between +18.0ºC and +25.0ºC. The tissue equivalent material fluid temperature was controlled to give a maximum variation of ± 2.0ºC Prior to any SAR measurements on the EUT, system validation and material dielectric property measurements were conducted. In the absence of a detailed procedure within the specification, system validation and material dielectric property measurements were performed in accordance with Appendix C and Appendix D of FCC OET Bulletin 65 Supplement C: 2001. Following the successful system validation and material dielectric property measurements, a SAR versus time sweep shall be performed within 10 mm of the phantom inner surface. If the EUT power output is stable after three minutes then the measurement probe will perform a coarse surface level scan at each test position in order to ascertain the location of the maximum local SAR level. Once this area had been established, a 7x7x7 cube of 343 points (5 mm spacing in each axis ≈ 27g) will be centred at the area of concern. Extrapolation and interpolation will then be carried out on the 27g of tissue and the highest averaged SAR over a 10g cube determined. Once the maximum interpolated SAR measurement is complete; the coarse scan is visually assessed to check for secondary peaks within 50% of the maximum SAR level. If there are any further SAR measurements required, extra 7x7x7 cubes shall be centred on each of these extra local SAR maxima. At the end of each position test case a second time sweep shall be performed to check whether the EUT has remained stable throughout the test.
