The devices can be easily, accurately, and repeatedly positioned according to the FCC and CENELEC specifications. The device holder can be locked at different phantom locations (left head, right head, flat phantom). 3.5. Scanning Procedure Device holder supplied by SATIMO The procedure for assessing the peak spatial-average SAR value consists of the following steps Power Reference Measurement The reference and drift jobs are useful jobs for monitoring the power drift of the device under test in the batch process. Both jobs measure the field at a specified reference position, at a selectable distance from the phantom surface. The reference position can be either the selected section's grid reference point or a user point in this section. The reference job projects the selected point onto the phantom surface, orients the probe perpendicularly to the surface, and approaches the surface using the selected detection method. Area Scan The Area Scan is used as a fast scan in two dimensions to find the area of high field values before running a detailed measurement around the hot spot.Before starting the area scan a grid spacing of 15 mm x 15 mm is set. During the scan the distance of the probe to the phantom remains unchanged. After finishing area scan, the field maxima within a range of 2 dB will be ascertained. Zoom Scan Zoom Scans are used to estimate the peak spatial SAR values within a cubic averaging volume containing 1 g and 10 g of simulated tissue. The default Zoom Scan is done by 7x7x7 points within a cube whose base is centered around the maxima found in the preceding area scan. Shenzhen LCS Compliance Testing Laboratory Ltd.

The drift measurement gives the field difference in dB from the reading conducted within the last reference measurement. Several drift measurements are possible for one reference measurement. This allows a user to monitor the power drift of the device under test within a batch process. In the properties of the Drift job, the user can specify a limit for the drift and have OPENSAR software stop the measurements if this limit is exceeded. 3.6. Data Storage and Evaluation Data Storage The OPENSAR software stores the acquired data from the data acquisition electronics as raw data (in microvolt readings from the probe sensors), together with all necessary software parameters for the data evaluation (probe calibration data, liquid parameters and device frequency and modulation data) in measurement files . The software evaluates the desired unit and format for output each time the data is visualized or exported. This allows verification of the complete software setup even after the measurement and allows correction of incorrect parameter settings. For example, if a measurement has been performed with a wrong crest factor parameter in the device setup, the parameter can be corrected afterwards and the data can be re-evaluated. The measured data can be visualized or exported in different units or formats, depending on the selected probe type ([V/m], [A/m], [°C], [mW/g], [mW/cm²], [dBrel], etc.). Some of these units are not available in certain situations or show meaningless results, e.g., a SAR output in a lossless media will always be zero. Raw data can also be exported to perform the evaluation with other software packages. Data Evaluation The OPENSAR software automatically executes the following procedures to calculate the field units from the microvolt readings at the probe connector. The parameters used in the evaluation are stored in the configuration modules of the software: Probe parameters: - Sensitivity Normi, ai0, ai1, ai2 - Conversion factor ConvFi - Diode compression point Dcpi Device parameters: - Frequency f - Crest factor cf Media parameters: - Conductivity - Density These parameters must be set correctly in the software. They can be found in the component documents or they can be imported into the software from the configuration files issued for the OPENSAR components. In the direct measuring mode of the multimeter option, the parameters of the actual system setup are used. In the scan visualization and export modes, the parameters stored in the corresponding document files are used. The first step of the evaluation is a linearization of the filtered input signal to account for the compression characteristics of the detector diode. The compensation depends on the input signal, the diode type and the DC-transmission factor from the diode to the evaluation electronics.If the exciting field is pulsed, the crest factor of the signal must be known to correctly compensate for peak power. The formula for each channel can be given as: With Vi = compensated signal of channel i ( i = x, y, z ) Ui = input signal of channel i ( i = x, y, z ) cf = crest factor of exciting field dcpi = diode compression point From the compensated input signals the primary field data for each channel can be evaluated: With Vi Normi ConvF = compensated signal of channel i = sensor sensitivity of channel i [mV/(V/m)2] for E-field Probes = sensitivity enhancement in solution (i = x, y, z) (i = x, y, z) Shenzhen LCS Compliance Testing Laboratory Ltd.

SAR measurement procedure The measurement procedures are as follows: Face-Held Configuration Face-held Configuration- per FCC KDB447498 page 22: "A test separation distance of 25 mm must beapplied for in-front-of the face SAR test exclusion and SAR measurements."Per FCC KDB643646 Apppendix Head SAR Test Considerations: "Passive body-worn and audio accessoriesgenerally do not apply to the head SAR of PTT radios. Head SAR is measured with the front surface of theradio positioned at 2.5cm paralled to a flat phantom. A phantom shell thicjnes of 2mm is reguired. When thefront of the radio has a contour or non-uniform surface with a variation of 1.0cm or more, the average distanceof such variations is used to establish the 2.5cm test separartion from the phantom. Body-worn Configuration Body-worn measurements-per FCC KDB447498 page 22 "When body-worn accessory SAR testing isrequired, the bodyworn accessory requirements in section 4.2.2 should be applied. PTT two-way radios thatsupport held-to-ear operating mode must also be tested according to the exposure configurations required forhandsets. This generally does not apply to cellphones with PTT options that have already been tested inmore conservative configurations in applicable wireless modes for SAR compliance at 100% duty factor.'According to KDB643646 D01 for Body SAR Test Considerations for Body-worn Accessoires: Body SAR ismeasured with the radio placed in a body-worn accessory, positioned against a flat plantom, representative ofthe normal operating conditions expected by users and typically with a standard default audio accessorysupplied with the radio, may be designed to operate with a subset of the combinations of antennas, batteriesand body-worn accessores, when a default audio accessory does not fully support all accessory must beselected to be the default audio accessory for bodv-worn accessories testing, lf an altermative audio accessorvcannot be identified, body-worn accessories should be tested without any body accessories should be testedwithout any audio. In general, all sides of the radio that may be positioned facing the user when using a body.worn accessory must be condisered for SAR compliance. 3.12.

Power Drift To control the output power stability during the SAR test, SAR system calculates the power drift by measuring the E-field at the same location at the beginning and at the end of the measurement for each test position. This ensures that the power drift during one measurement is within 5%. Shenzhen LCS Compliance Testing Laboratory Ltd.

Power Results According KDB 447498D01 General RF Exposure Guidance v06 Section 4.1 2) states that "Unless it is specified differently in the published RF exposure KDB procedures, these requirements also apply to test reduction and test exclusion considerations. Timeaveraged maximum conducted output power applies to SAR and, as required by § 2.1091(c), time-averaged ERP applies to MPE. When an antenna port is not available on the device to support conducted power measurement, such as FRS and certain Part 15 transmitters with built-in integral antennas, the maximum output power allowed for production units should be used to determine RF exposure test exclusion and compliance." SAR may be scaled if radio is tested at lower power without overheating as invalid SAR results cannot bescaled to compensate for power droop according to October 2015 TCB Workshop.
