Q: 2.how to solve the problem of mobile phone prompt unable to connect? A: delete the pairing record on the mobile phone, and then search signal and connect again. Q: A: 3.Why there is no sound in the call / music? Android phone has a setting icon on the right side of the phone connection record. Click enter to uncheck and reselect the two audio options. Apple phone sets the general auxiliary function to enter the audio call mode. Select auto. If it is auto, change other options, and then select auto. If it is not recovered, delete the matching record and try again. Q: A: 4.Why there is a delay in the video / gameplay? Due to the influence of environment, network and mobile phone encoding and decoding speed, it will cause different degrees of delay when the mobile phone transmits audio data to the earbuds.( When the real-time voice function is enabled in the game, the definition of the game background sound will be affected, so the current game software sets the Bluetooth transmission rate as priority.) Q: A: 5.Why is it stuck / intermittent? If there are a large number of WiFi connections, 4G signals, high-power electrica l appliances and so on when using, it may be stuck or intermittent. It can be solved by changing the environment or repairing and connecting. 1. Please use the original or with safety certification wire harness for charging. 2. When using earbuds, please adjust the volume appropriately to avoid damaging the hearing. 3. Please use the product correctly to avoid falling or heavy extrusion. 4. Children should be accompanied by adults to avoid eating by mistake. 5. Keep away from extreme environment such as high temperature or humidity. 6. Do not disassemble this product. 7.Earbuds can't be charged in charging case if earbuds are equipped with L eartips.

RF EXPOSURE EVALUATION METHOD FCC ID: 2AWIE-TT15B SAR Test Exclusion Thresholds for 100 MHz – 6 GHz and ≤ 50 mm Approximate SAR Test Exclusion Power Thresholds at Selected Frequencies and Test Separation Distances are illustrated in the following Table. 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 The result is rounded to one decimal place for comparison The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. BT-EDR max possible output power (PK,conducted)：-3±1dbm 0dBi logarithmic terms convert to numeric result is nearly 1. -2dbm=0.63mW 2402MHz [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance,mm)] · [√f(GHz)]=0.63/5*√2. 402 =0. 20≤3.0 Threshold at which no SAR required is 10mw and ≤ 3.0 for 1-g SAR, Separation distance is 5mm.
