HOW TO WEAR Choose the Right Tips (Fig. 3) Ear tips with different sizes are included in the package, try all sizes and choose the ones fitting you best. 3 0304 Wear the Earbuds (Fig. 4) Please wear the earbuds as shown below. Pictures only for reference. Bluetooth Caution • When the device is connected wirelessly to another device, place the two devices close to each other to achieve their normal functionalities and avoid possible signal interference. • When using a wireless connection, make sure there are no obstacles between the two devices. Obstacles including walls and fences may shorten the effective range. USING YOUR EARBUDS Charging Charging the Earbuds 1. Put the earbuds into the charging case as per the L (left) and R (right) marks (Fig. 5). 2. Cover the lid and charging will start automatically (Fig. 6). Note: • Please fully charge the earbuds when using them for the first time. • When battery is low, a “Battery low” voice prompt will be heard (if you are wearing the earbuds). Please charge it in time or the earbuds will turn off automatically around 10 minutes later. • Charge the earbuds at least once every 3 months when not using for a long time. Charging the Charging Case 1. Connect the charging port with any USB charging adapter or…

RF EXPOSURE EVALUATION 1. PRODUCT INFORMATION Product Description TRUE WIRELESS STEREO EARBUDS Model Name BT-BH021 FCC ID 2AFDGBT-BH021 2. EVALUATION METHOD According to 447498 D01 General RF Exposure Guidance v05 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 f(GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation 3. CALCULATION P t =2.468dBm=1.77mW The value of the Maximum output power P t is referred to the test report of the CFR47 §15.247. The result for RF exposure evaluation SAR=(1.77mW /5mm) .[√2.402(GHz)]= 0.55<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. 4. CONCLUSION The SAR evaluation is not required.

MEASUREMENT PROCEDURE The EUT shall have its hopping function enabled. Use the following spectrum analyzer settings: 1. Span: The frequency band of operation. Depending on the number of channels the device supports, it may be necessary to divide the frequency range of operation across multiple spans, to allow the individual channels to be clearly seen. 2. RBW: To identify clearly the individual channels, set the RBW to less than 30% of the channel spacing or the 20 dB bandwidth, whicheve…
