FCC RF Exposure EUT Description: Smart Watch TWS Headset Model No.: X7 FCC ID: 2BB2C-X7 1. Limits According to KDB 447498 D01 General RF Exposure Guidance v01 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: Result=P/D*√F F= the RF channel transmit frequency in GHz P=Maximum turn‐up power in mw D=Min. test separation distance in mm 2. Test Result of RF Exposure Evaluation Output power (dBm) Tune Up Power (dBm) Max Tune Up power dBm/mW Min test separati on distance mm Result Limit SAR Test Exclusion BLE 3.17 3±1(4) 2.51 5 0.79114 3.0 Pass Note: PK Output power= conducted power. Conducted power see the test report HK2306252657-E, antenna gain=2.28dBi Per KDB 447498 D01, when the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. The test exclusion threshold is 0.79114 which is<= 3, SAR testing is not required. Note: Exclusion Thresholds Results=[(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f (GHz)] f(GHz) is the RF channel transmit frequency in GHz Distance=5mm

The minimum amount of solder can lead to damage from the stresses caused by the difference in coefficients of expansion between solder, chip and substrate. The terminations are suitable for all wave and re-flow soldering systems. If hand soldering cannot be avoided, the preferred technique is the utilization of hot air soldering tools. Recommended temperature profiles for re-flow soldering in Figure 1. Products attachment with a soldering iron is discouraged due to the inherent process control limitations. In the event that a soldering iron must be employed the following precautions are recommended. ‧Preheat circuit and products to 150°C ‧Never contact the ceramic with the iron tip ‧Use a 20 watt soldering iron with tip diameter of 1.0mm ‧280°C tip temperature (max) ‧1.0mm tip diameter (max) ‧Limit soldering time to 3 sec.
