Decrease the volume: Swipe down repeatedly until the volume reaches the desired level. Change the volume continuously: Swipe up or down and hold. Release at the desired volume level. When the volume reaches the maximum or minimum, an alarm sounds. 4 When you finish your phone call, tap the touch sensor control panel twice quickly (with an interval of about 0.4 seconds) to end the call. If you received a call during music playback, music playback resumes automatically after ending the call. Hint When receiving a call by operating smartphones or mobile phones, some smartphones or mobile phones receive a call with the phone instead of the headset. With an HFP or HSP connection, switch the call to the headset by holding your finger to the headset's touch sensor control panel until it switches, or by using your smartphone or mobile phone. Volume for a call can be adjusted during a telephone conversation only. The headset volume during a call and during music playback can be independently adjusted. Changing the call volume does not change the volume of music playback and vice versa. Note Depending on the smartphone or mobile phone, when an incoming call arrives while you are listening to music, playback may not resume automatically even if you finish the call. Use a smartphone or mobile phone at least 50 cm (19.69 in.) away from the headset. Noise may result if the smartphone or mobile phone is too close to the headset. Your voice will be heard from the headset through the headset's microphone (Sidetone function). In this case, ambient sounds or the sounds of the headset operation may be heard through the headset, but this is not a malfunction.
