FCC ID: ARURPV516A 2 Portable VHF PTT Radio Transceiver (150-174MHz) 3.0 SAR MEASUREMENT SYSTEM Celltech Research SAR measurement facility utilizes the Dosimetric Assessment System (DASY™) manufactured by Schmid & Partner Engineering AG (SPEAG™) of Zurich, Switzerland. The DASY system is comprised of the robot controller, computer, near-field probe, probe alignment sensor, and the SAM phantom containing brain or body 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, is used to drive the robot motors. The Staubli robot is connected to the cell controller to allow software manipulation of the robot. A data acquisition electronic (DAE) circuit performs the signal amplification, signal multiplexing, AD-conversion, offset measurements, mechanical surface detection, collision detection, etc. 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 utilizes a highly sensitive electrometer-grade preamplifier with auto-zeroing, a channel and gain-switching multiplexer, 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. DASY3 SAR Measurement System with SAM phantom

FCC ID: ARURPV516A 5 Portable VHF PTT Radio Transceiver (150-174MHz) 5.0 DETAILS OF SAR EVALUATION The RELM WIRELESS CORP. Model: RPV516A Portable VHF PTT Radio Transceiver FCC ID: ARURPV516A was found to be compliant for localized Specific Absorption Rate (Controlled Exposure) based on the following test provisions and conditions: 1. The EUT was tested in a face-held configuration with the front of the device placed parallel to the outer surface of the planar phantom and with a 2.5cm separation distance. 2. The EUT was tested in a body-worn configuration with the attached belt-clip touching the outer surface of the planar phantom and providing a 1.4cm separation distance between the back of the EUT and the outer surface of the planar phantom. 3. The EUT was evaluated for SAR at maximum power and the unit was operated for an appropriate period prior to the evaluation in order to minimize drift. The conducted power level was checked before and after each test. 4. The conducted power was measured according to the procedures described in FCC Part 2.1046. 5. The location of the maximum spatial SAR distribution (Hot Spot) was determined relative to the device and its antenna. 6. The EUT was tested with a fully charged battery. Note: Under continuous transmission the antenna became very warm and began to droop slightly. The device was cooled for brief periods during the evaluation in order to stabilize the antenna. The lower than expected SAR values reported for this particular EUT operating at the rated power levels can be attributed to excessive heating in the plastic antenna housing. 6.0 EVALUATION PROCEDURES The Specific Absorption Rate (SAR) evaluation was performed in the following manner: a. (i) The evaluation was performed in the applicable area of the phantom depending on the type of device being tested. For devices held to the ear during normal operation, both the left and right ear positions were evaluated in accordance with FCC OET Bulletin 65, Supplement C (Edition 01-01). (ii) For body-worn and face-held devices the planar section of the phantom was used. b. The SAR was determined by a pre-defined procedure within the DASY3 software. Upon completion of a reference and optical surface check, the exposed region of the phantom was scanned near the inner surface with a grid spacing of 20mm x 20mm. c. For frequencies below 500MHz a 4x4x7 matrix was performed around the greatest spatial SAR distribution found during the area scan of the applicable exposed region. For frequencies above 500MHz a 5x5x7 matrix was performed. 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. e. The E-field probe conversion factors outside the calibrated points were determined as follows: • In brain and body tissue between 750MHz and 1GHz, the conversion factor decreases approximately 1.3% per 100MHz frequency increase. • In brain and body tissue between 1.6GHz and 2GHz, the conversion factor decreases approximately 1% per 100MHz frequency increase. For body tissue around 900MHz (permittivity about 30% higher and conductivity about 15% higher than brain tissue): • The conversion factor in body tissue is approximately 3% lower than for brain tissue for the same frequency.

According to ANSI/IEEE C95.3, the overall uncertainties are difficult to assess and will vary with the type of meter and usage situation. However, accuracy’s of ± 1 to 3 dB can be expected in practice, with greater uncertainties in near-field situations and at higher frequencies (shorter wavelengths), or areas where large reflecting objects are present. Under optimum measurement conditions, SAR measurement uncertainties of at least ± 2dB can be expected. According to CENELEC, typical worst-case uncertainty of field measurements is ± 5 dB. For well-defined modulation characteristics the uncertainty can be reduced to ± 3 dB.

FCC ID: ARURPV516A 16 Portable VHF PTT Radio Transceiver (150-174MHz) APPENDIX D - DETERMINATION OF E-FIELD PROBE CONVERSION NUMBERS
Determination of Probe Conversion Factors for 150MHz Since at this time there exists no experimental method in determining E-field probe conversion factors for frequencies below 800MHz, the following procedure was carried out to give an approximation of the probe conversion factors for 150MHz. The accuracy of the system was determined based on the two calibrated test frequencies of 900 and 1800MHz, using validation dipoles as supplied by the manufacturer. The measured results were found to be within the specified tolerances. For conversion factors outside these two frequencies a linear extrapolation was performed as per the manufacturer’s recommendations. In order to determine the accuracy of the conversion factors, 300 and 450MHz dipoles were constructed in accordance with IEEE Std. P1528. The two dipoles were then characterized for SAR using the appropriate head simulating fluid for the given frequencies in a planar phantom as prescribed in IEEE Std. P1528. The table below indicates the analytical target values for each dipole with the associated measured results. Frequency (MHz) Analytical SAR @ 1W input averaged over 1 gram Measured SAR @ 1W input averaged over 1 gram Delta ∆∆ Fluid Parameters εr=45.3 300 3.0 3.51 17.0% σ=0.87 εr=43.5 450 4.9 5.77 17.8% σ=0.87 The extrapolated head conversion factors determined for 300 and 450MHz resulted in SAR values being 17.0% and 17.8% greater than expected for each frequency respectively. It is assumed that as this extrapolation is extended down to 150MHz, the resulting SAR will again be overestimated by at least 17%. The body conversion factors were determined based on a combination of the obtained data from the validations, and numerical modeling results from an identical probe from the same manufacturer. The following two pages show examples of the conversion factors that were derived through numerical modeling for a probe of similar properties.

In addition, the above graphs and tabular results show that the probe conversion factors vary only slightly between head and body as the frequency approaches 450MHz. It is therefore safe to assume that as the frequency is further extended to 150MHz, the difference in the conversion factors between head and body will be less significant. Therefore, for this reason only one conversion factor is reported for both head and body at 150MHz.

Application Note: SAR SensitivitiesSchmid & Partner Engineering AG, Zurich, SwitzerlandApplication Note: SAR SensitivitiesIntroductionThe measured SAR-values in homogeneous phantoms depend strongly on the electricalparameters of the liquid. Liquids with exactly matching parameters are difficult to produce;there is always a small error involved in the production or measurement of the liquidparameters. The following sensitivities allow the estimation of the influence of smallparameter errors on the measured SAR values. The calculations are based on anapproximation formula [1] for the SAR of an electrical dipole near the phantom surface anda adapted plane wave approximation for the penetration depth. The sensitivities are given inpercent SAR change per percent change in the controlling parameter: d SAR / SARS(x) = ——————— d x / xThe controlling parameters x are:• ε: permitivity• σ: conductivity• ρ: brain density (= one over integration volume)For example: If The liquid permitivity increases by 2 percent and the sensitivity of the SARto permitivity is -0.6 then the SAR will decrease by 1.2 percent.The sensitivities are given for surface SAR values and averaged SAR values for 1 g and 10g cubes and for dipole distances d of 10mm (for frequencies below 1000 MHz) and 15mm(for frequencies above 1000 MHz) from the liquid surface.Liquid parameters are as proposed in the new standards (e.g., IEEE 1528).References[1] N.
