Notes: ● Make sure the earbuds and your Bluetooth device are next to each other within 33 feet or 10 meters and there are no obstacles between. ● If pairing failed, put the earbuds back into the charging case make sure that they have been turned off. Then pair the earbuds with your Bluetooth device again. ● When the earbuds are on but not paired with a Bluetooth device, they will be automatically off after 5 minutes. ● The earbuds will connect to the last paired Bluetooth device automatically when they are turned on. Please turn on the Bluetooth of your Bluetooth device before turning on the earbuds. - 7 - Primary/Secondary mode These earbuds have primary-secondary switch function. ● When the earbuds have been connected to a Bluetooth device, take out either of the two earbuds, it can be connected and used normally. During this period, you can take out the other one and they will pair with each other so you can use both of the earbuds. ● When both earbuds are connected to your phone, no matter which one is put back to the charging case, you can use the other one without interruption. Earbuds functions Function Play/Pause Next track Previous track What to do Tap the touch button of the left/right earbud. Double-tap the touch button of the left/right earbud. Tap the touch button of the left/right earbud three times. - 8 - Call functions Function Answer/end a call Decline an incoming call What to do Tap the touch button of the left/right earbud.

RF Exposure evaluation 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 The result is rounded to one decimal place for comparison For Bluetooth BR&EDR pt=-3.46dBm =0.451mW at 2480MHz So (0.451mW/5mm)x √2.480GHz =0.14<3 For Bluetooth BLR pt=-2.86dBm =0.518mW at 2440MHz So (0.518mW/5mm)x √2.440GHz =0.16<3 Then SAR evaluation is not required FCC ID:2AR5E-T16
