FCC SAR TEST REPORT
Report No. : FA9O2119
10.5 Body Worn Accessory
Body-worn operating configurations are tested with the belt-clips and holsters attached to the device and positioned
against a flat phantom in a normal use configuration (see Figure 9.4). Per KDB648474 D04v01r03, body-worn accessory
exposure is typically related to voice mode operations when handsets are carried in body-worn accessories. The
body-worn accessory procedures in FCC KDB 447498 D01v06 should be used to test for body-worn accessory SAR
compliance, without a headset connected to it. This enables the test results for such configuration to be compatible with
that required for hotspot mode when the body-worn accessory test separation distance is greater than or equal to that
required for hotspot mode, when applicable. When the reported SAR for body-worn accessory, measured without a
headset connected to the handset is > 1.2 W/kg, the highest reported SAR configuration for that wireless mode and
frequency band should be repeated for that body-worn accessory with a handset attached to the handset.
Accessories for body-worn operation configurations are divided into two categories: those that do not contain metallic
components and those that do contain metallic components and those that do contain metallic components. When
multiple accessories that do not contain metallic components are supplied with the device, the device is tested with only
the accessory that dictates the closest spacing to the body. Then multiple accessories that contain metallic components
are test with the device with each accessory. If multiple accessories share an identical metallic component (i.e. the same
metallic belt-chip used with different holsters with no other metallic components) only the accessory that dictates the
closest spacing to the body is tested.

10.6 Wireless Router
Some battery-operated handsets have the capability to transmit and receive user through simultaneous transmission of
WIFI simultaneously with a separate licensed transmitter. The FCC has provided guidance in FCC KDB Publication
941225 D06 v02r01 where SAR test considerations for handsets (L x W ≥ 9 cm x 5 cm) are based on a composite test
separation distance of 10mm from the front, back and edges of the device containing transmitting antennas within 2.5cm
of their edges, determined form general mixed use conditions for this type of devices. Since the hotspot SAR results may
overlap with the body-worn accessory SAR requirements, the more conservative configurations can be considered, thus
excluding some body-worn accessory SAR tests.
When the user enables the personal wireless router functions for the handset, actual operations include simultaneous
transmission of both the WIFI transmitter and another licensed transmitter. Both transmitters often do not transmit at the
same transmitting frequency and thus cannot be evaluated for SAR under actual use conditions due to the limitations of
the SAR assessment probes. Therefore, SAR must be evaluated for each frequency transmission and mode separately
and spatially summed with the WIFI transmitter according to FCC KDB Publication 447498 D01v06 publication
procedures. The “Portable Hotspot” feature on the handset was NOT activated during SAR assessments, to ensure the
SAR measurements were evaluated for a single transmission frequency RF signal at a time.
