Report No.: 14U19370-S1 FCC ID: 2AB8ZND2 Issue Date: 12/5/2014 4. SAR Measurement System & Test Equipment 4.1. SAR Measurement System The DASY5 system used for performing compliance tests consists of the following items:  A standard high precision 6-axis robot with controller, teach pendant and software. An arm extension for accommodating the data acquisition electronics (DAE).  An isotropic Field probe optimized and calibrated for the targeted measurement.  A data acquisition electronics (DAE) which performs the signal amplification, signal multiplexing, AD- conversion, offset measurements, mechanical surface detection, collision detection, etc. The unit is battery powered with standard or rechargeable batteries. The signal is optically transmitted to the EOC.  The Electro-optical converter (EOC) performs the conversion from optical to electrical signals for the digital communication to the DAE. To use optical surface detection, a special version of the EOC is required. The EOC signal is transmitted to the measurement server.  The function of the measurement server is to perform the time critical tasks such as signal filtering, control of the robot operation and fast movement interrupts.  The Light Beam used is for probe alignment. This improves the (absolute) accuracy of the probe positioning.  A computer running WinXP or Win7 and the DASY5 software.  Remote control and teach pendant as well as additional circuitry for robot safety such as warning lamps, etc.  The phantom, the device holder and other accessories according to the targeted measurement.

Report No.: 14U19370-S1 FCC ID: 2AB8ZND2 Issue Date: 12/5/2014 4.2. SAR Scan Procedure The following custom procedure was prescribed by SPEAG: Step 1: Phantom Position Measurements Phantom Position Measurements allows the technician to verify the points as well as verify the Z-coordinate of the Test Bed Plane. Step 2: SAR Measurement For this particular project, a modified Area Scan is used to perform the measurements. The internal volume of the wristband is minimal; thus, the Area Scan parameters are smaller than prescribed by 865664 D01 SAR Measurement 100 MHz to 6 GHz v01r03. This allows enough coverage to measure SAR efficiently and precisely. Page 8 of 22 UL Verification Services Inc. Doc.

Report No.: 14U19370-S1 FCC ID: 2AB8ZND2 Issue Date: 12/5/2014 4.3. Test Rationale and Procedure The DUT’s unique rigid wrist worn design and antenna implementation necessitated the use of provisional measurement methods in order for scans to be performed in areas inaccessible by standard methods. Given the stated complications and the inconsistent nature of provisional measurement methods in general, however, any and all approaches taken would require review and approval by the FCC for the results to be acceptable. For this purpose, the test lab adopted the following materials and procedure, taken from SPEAG’s technical note “Smart-watch Testing with DASY52” and approved by the FCC, to facilitate measurements and conditions that best simulated the exposure conditions the end-user would be subjected to. These procedures and materials were then reviewed by the FCC and further refined until deemed acceptable by the FCC. Purpose To ensure precise robot controlled detection and good accessibility of the internal volume of the wristband. Materials  A test-bed made from low-loss material (which dielectric parameters are listed in Section 11)  A plastic anchor: to hold the watch phantom in a constant position for repeatability  Styrofoam doughnut: to emulate free space  Vacuum sealer/bags: to prevent the Muscle Simulating Liquid from damaging the DUT Procedure 1. Build a test-bed, or watch phantom, made from low-loss, low-permittivity material, but rigid surface. a. It is recommended to use a test-bed size of 20x20 cm. 2. Build an anchor that fits within an ELI Phantom and that can hold the watch phantom in place. 3. Place both the anchor and watch phantom inside a dry ELI Phantom; teach the robot the watch phantom’s three reference points (as demonstrated in Appendix A) using surface detection. 4. Once the phantom has been taught, run Step 1 of the DASY test file, provided by SPEAG. a. Make sure the proprieties for Z as close to 0mm as possible.. b. Step 1 is used to determine the Test Bed Plane location (Z axis) to ensure that probe distance from the DUT is a consistent 4mm. 5. Export the newly taught watch phantom and import the phantom into Step 2 of the DASY test file, provided by SPEAG. a. Measurements performed in Step 2 will use a special probe configuration provided by SPEAG that performs Area Scan measurements without surface detection,. 6. Seal the DUT in a vacuum sealed bag and insert it into the watch phantom. 7. Place the watch phantom with the DUT in/on the anchor and begin Step 2 to perform the measurement. a. The dimensions of these Area Scan measurements can be found in the corresponding plots. b. A Pre-Scan is run to determine a location in which to do Power Reference measurement. This is followed by an Area Scan and finally a Power Drift measurement is taken. 8. The measurement results were then post-processed by SPEAG to determine the actual 10-g SAR, and routine measurement warning messages that occurred due to the unusual nature of the measurements were also confirmed to be negligible by SPEAG. The warning messages are related to the maximum deviation angle of the probe to the normal surface. This limit has been extended to allow larger measurement area inside the watch.

Dielectric Property Measurements Results The temperature of the tissue-equivalent medium used during measurement must also be within 18C to 25C and within ± 2C of the temperature when the tissue parameters are characterized. The dielectric parameters must be measured before the tissue-equivalent medium is used in a series of SAR measurements. The parameters should be re-measured after each 3 – 4 days of use; or earlier if the dielectric parameters can become out of tolerance; for example, when the parameters are marginal at the beginning of the measurement series. Tissue dielectric parameters were measured at the low, middle and high frequency of each operating frequency range of the test device. SAR Lab 4 Date Freq.

Report No.: 14U19370-S1 FCC ID: 2AB8ZND2 Issue Date: 12/5/2014 9. System Check SAR system verification is required to confirm measurement accuracy, according to the tissue dielectric media, probe calibration points and other system operating parameters required for measuring the SAR of a test device. The system verification must be performed for each frequency band and within the valid range of each probe calibration point required for testing the device. The same SAR probe(s) and tissue-equivalent media combinations used with each specific SAR system for system verification must be used for device testing. When multiple probe calibration points are required to cover substantially large transmission bands, independent system verifications are required for each probe calibration point. A system verification must be performed before each series of SAR measurements using the same probe calibration point and tissue-equivalent medium. Additional system verification should be considered according to the conditions of the tissue-equivalent medium and measured tissue dielectric parameters, typically every three to four days when the liquid parameters are re-measured or sooner when marginal liquid parameters are used at the beginning of a series of measurements. 9.1. System Performance Check Measurement Conditions  The measurements were performed in the flat section of the TWIN SAM or ELI phantom, shell thickness: 2.0 ±0.2 mm (bottom plate) filled with Body or Head simulating liquid of the following parameters.  The depth of tissue-equivalent liquid in a phantom must be ≥ 15.0 cm for SAR measurements ≤ 3 GHz and ≥ 10.0 cm for measurements > 3 GHz.  The DASY system with an E-Field Probe was used for the measurements.  The dipole was mounted on the small tripod so that the dipole feed point was positioned below the center marking of the flat phantom section and the dipole was oriented parallel to the body axis (the long side of the phantom). The standard measuring distance was 10 mm (above 1 GHz) and 15 mm (below 1 GHz) from dipole center to the simulating liquid surface.  The coarse grid with a grid spacing of 15 mm was aligned with the dipole. For 5 GHz band - The coarse grid with a grid spacing of 10 mm was aligned with the dipole.  Special 7x7x7 (below 3 GHz) and/or 8x8x7 (above 3 GHz) fine cube was chosen for the cube.  Distance between probe sensors and phantom surface was set to 3 mm. For 5 GHz band - Distance between probe sensors and phantom surface was set to 2.5 mm  The dipole input power (forward power) was 100 mW.  The results are normalized to 1 W input power. 9.2. Reference Target SAR Values The reference SAR values are obtained from the calibration certificate of system validation dipoles. The measured values are normalized to 1 Watt.

These additional measurements are repeated after the completion of all measurements requiring the same head or body tissue-equivalent medium in a frequency band. The test device should be returned to ambient conditions (normal room temperature) with the battery fully charged before it is re-mounted on the device holder for the repeated measurement(s) to minimize any unexpected variations in the repeated results. 1) Repeated measurement is not required when the original highest measured SAR is < 2 W/kg; steps 2) through 4) do not apply. 2) When the original highest measured SAR is ≥ 2 W/kg, repeat that measurement once. 3) Perform a second repeated measurement only if the ratio of largest to smallest SAR for the original and first repeated measurements is > 1.2 or when the original or repeated measurement is ≥ 3.625 W/kg (~ 10% from the 10g SAR limit). 4) Perform a third repeated measurement only if the original, first or second repeated measurement is ≥3.75 W/kg and the ratio of largest to smallest SAR for the original, first and second repeated measurements is > 1.2.
