The neck region of the SAM phantom was chosen for wrist-worn extremity SAR testing in accordance with KDB
447498 §6.2.
A non-standard setup was used for SAR testing based on guidance from the FCC. The operational description
contains additional information.

8. Dielectric Property Measurements & System Check
8.1. Dielectric Property Measurements
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.

10.3. Wi-Fi (DTS Band) and Bluetooth
Standalone SAR Test Exclusion Considerations & Estimated SAR
The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances
≤ 50 mm are determined by:
[(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)]·[√f(GHz)] ≤ 3.0, for 1-g SAR
and ≤ 7.5 for 10-g extremity SAR, where
 f(GHz) is the RF channel transmit frequency in GHz
 Power and distance are rounded to the nearest mW and mm before calculation
 The result is rounded to one decimal place for comparison
The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for
transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a
distance of 5 mm is applied to determine SAR test exclusion.

When the standalone SAR test exclusion is applied to an antenna that transmits simultaneously with other
antennas, the standalone SAR must be estimated according to following to determine simultaneous transmission
SAR test exclusion:
 (max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)]·[√f(GHz)/x] W/kg for test
separation distances ≤ 50 mm;
where x = 7.5 for 1-g SAR, and x = 18.75 for 10-g SAR.
 0.4 W/kg for 1-g SAR and 1.0 W/kg for 10-g SAR, when the test separation distances is > 50 mm.

11. SAR Measurement Variability
In accordance with published RF Exposure KDB 865664 D01 SAR measurement 100 MHz to 6 GHz. 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 < 0.80 W/kg; steps 2)
through 4) do not apply.
2) When the original highest measured SAR is ≥ 0.80 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 > 1.20 or when the original or repeated measurement is ≥ 1.45 W/kg (~ 10% from
the 1-g SAR limit).
4) Perform a third repeated measurement only if the original, first or second repeated measurement is ≥1.5 W/kg
and the ratio of largest to smallest SAR for the original, first and second repeated measurements is > 1.20.
