2. Device Category and RF Exposure Limit
Per user manual, Based on 47CFR 2.1091, this device belongs to mobile device category with
General Population/Uncontrolled exposure.
Mobile Devices:
47CFR 2.1091(b)
For purposes of this section, a mobile device is defined as a transmitting device designed to be
used in other than fixed locations and to generally be used in such a way that a separation distance
of at least 20 centimeters is normally maintained between the transmitter's radiating structure(s)
and the body of the user or nearby persons. In this context, the term “fixed location” means that the
device is physically secured at one location and is not able to be easily moved to another location.
Transmitting devices designed to be used by consumers or workers that can be easily re-located,
such as wireless devices associated with a personal computer, are considered to be mobile devices
if they meet the 20 centimeter separation requirement.
GENERAL POPULATION / UNCONTROLLED EXPOSURE
The general population/uncontrolled exposure limits are applicable to situations in which the
general public may be exposed or in which persons who are exposed as a consequence of their
employment may not be made fully aware of the potential for exposure or cannot exercise control
over their exposure. Members of the general public would come under this category when exposure
is not employment-related; for example, in the case of a wireless transmitter that exposes persons
in its vicinity. Warning labels placed on low-power consumer devices such as cellular telephones
are not considered sufficient to allow the device to be considered under the occupational/controlled
category, and the general population/uncontrolled exposure limits apply to these devices.

Note:
1. According to KDB 447498, SAR test exclusion conditions are based on source-based time-averaged
     maximum conducted output power of the RF channel requiring evaluation, adjusted for tune-up
     tolerance, and the minimum test separation distance required for the exposure conditions.
2. For 5GHz WLAN, only the worst case will be used for calculating the power density.
3. The Bluetooth belongs low power transmitters, according to KDB 447498 section 4.3.1, the 1-g SAR test
     exclusion thresholds 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.
           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
                                                                           Max.                   Test                                  exclusion

     Therefore SAR is not required for Bluetooth mode.


4. MPE calculate method
                          Power Density = EIRP/4πR²
    Where: EIRP = P+G
             P = Output Power (dBm)
             G = Antenna Gain (dBi)
             R = Separation Distance (20cm)

1.    This device contains transmitters that may operate simultaneously. Therefore simultaneous transmission
      analysis is required. Per FCC KDB 447498 D01v06, simultaneous transmission SAR test exclusion may
      be applied when the sum of the 1-g SAR for all the simultaneous transmitting antennas in a specific a
      physical test configuration is ≤1.6 W/kg. When standalone SAR is not required to be measured, per FCC
      KDB 447498 D01v06 4.3.2), the following equation must be used to estimate the standalone 1g SAR for
      simultaneous transmission assessment involving that transmitter.
