REPORT No.：SZ18120092S01 2. Device Category and RF Exposure Limit Per user manual, this device is a Bluetooth peak with rechargeable battery. 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.

REPORT No.：SZ18120092S01 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 0.50mW @ 2.402GHz When Bluetooth Cooler Speaker is used on the hand, 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)] =0.16≤3.0 So SAR evaluation is not required for this device. Note: Declaration of the tune-up limit is -3.00dBm. MORLAB SHENZHEN MORLAB COMMUNICATIONS TECHNOLOGY Co., Ltd.
