To mute or unmute the microphone 
during a call, press the volume key. The 
headset beeps, and a related icon is 
displayed on your device (if supported 
by the device).
To switch a call between the headset 
and a compatible connected device, 
press and hold the answer/end key for 
about 2 seconds.
Manage two calls
To manage two calls at the same time, 
your mobile device must support the 
Bluetooth Hands-Free Profile 1.5, and 
call waiting must be activated in the 
device. Call waiting is a network 
service and is available when the 
headset is connected to only one 
device.
To answer a waiting call and end the 
active call, press the answer/end key.
To answer a waiting call and put the 
active call on hold, press and hold the 
answer/end key for about 2 seconds.
To end the active call and make the 
call on hold active, press the answer/
end key.
To switch between the active call and 
the call on hold, press and hold the 
answer/end key for about 2 seconds.
Turn lights on or off
By default, the indicator lights are 
shown in all situations. To turn the 
lights off in some situations (for 
example, during a call or when the 
headset is connected to a mobile 
device), press and hold the answer/
end key, and slide and hold the volume 
key down for about 5 seconds when 
the headset is connected to a device. 
The yellow indicator light flashes 
once.
