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 pressing and holding the

(call) button for about 2 seconds 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 microphone on the left unit (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.
