Soon later, L & R earbuds pair automatically, and the R earbud LED indicator blinks in red and green color. Using single earbud mode If you only take out L or R earbud from the charging case, it turns on automatically with voice prompt "Power on", and the LED indicator on L or R earbud will blink in red and green alternately. Connect with your cell phone: When you hear voice prompts "Power on", after connected, R earbud LED indicator will blink red and green alternately. Activate your cell phone Bluetooth and search "TWS-10N". Choose and click "TWS-10N" on mobile phone, then you will hear "connected". Start to enjoy music after you finished the above steps. As soon as you take out TWS-10N from the charging case, long press R earbud 10 seconds till the red LED indicator on R earbud keep blinking 5 times, it means cleared pairing. Put the earbud into the charging case again and then take out both earbuds from the charging case, you can see earbud are in pairing mode with promps “Power on”. After paired, R earbud LED indicator blinks in red and green, then you can start using TWS-10N.

RF exposure evaluation FCC ID: 2ASBN-TWS-10N §2.1093 Radiofrequency radiation exposure evaluation: Portable Devices. According to§15.247(i) and§1.1307b(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the commission’s guidance. The 1-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, where  f(GHz) is the RF channel transmit frequency in GHz  Power and distance are rounded to the nearest mW and mm before calculation  When the minimum test separation distance is < 5 mm, a distance of 5 mm according is applied to determine SAR test exclusion.  The result is rounded to one decimal place for comparison  For BDR+EDR: Channel Frequency (GHz) Max.
