 2. Device category and RF exposure limit
 Per user manual, this device is a Hearing Aid. Based on 47CFR 2.1093, this device belongs to
 portable device category with General Population/Uncontrolled exposure.
 Portable Devices:
 47CFR 2.1093(b)
 For purposes of this section, a portable device is defined as a transmitting device designed to be
 used so that the radiating structure(s) of the device is/are within 20 centimeters of the body of the
 user.

 GENERAL POPULATION / UNCONTROLLED EXPOSURE
 47CFR 2.1093(d) (2)
 Limits for General Population/Uncontrolled exposure: 0.08 W/kg as averaged over the whole-body
 and spatial peak SAR not exceeding 1.6 W/kg as averaged over any 1 gram of tissue (defined as a
 tissue volume in the shape of a cube). Exceptions are the hands, wrists, feet and ankles where the
 spatial peak SAR shall not exceed 4 W/kg, as averaged over any 10 grams of tissue (defined as a
 tissue volume in the shape of a cube). General Population/Uncontrolled limits apply when the
 general public may be exposed, or when persons that are exposed as a consequence of their
 employment may not be fully aware of the potential for exposure or do not exercise control over
 their exposure. Warning labels placed on consumer devices such as cellular telephones will not be
 sufficient reason to allow these devices to be evaluated subject to limits for occupational/controlled
 exposure in paragraph (d)(1) of this section.

 4. RF exposure evaluation
 The device only incorporates a Bluetooth transmitter, so standalone SAR evaluation is required for
 Bluetooth and simultaneous SAR is not required.

 Standalone transmission SAR evaluation

 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
 The maximum tune-up limit power is -8.5dBm (0.14mW) @ 2.402GHz
 When Bluetooth Headset is used on the head, so use 5mm as the most conservative minimum test
 separation distance,
 [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance,
 mm)]·[√f(GHz)] =0.043 ≤ 3.0
 So SAR measurement is not required for this device.
