Call functions 
Active noise cancellation 
Noise from the surrounding environment is actively removed 
from your speech and at the earpiece using dual microphone 
noise cancellation technology. 
Noise picked up by a secondary microphone is removed from 
the signal of the main microphone into which you speak. This 
results in a significantly improved transmission of speech in 
a noisy environment. This feature is always activated. 
Additionally, you can activate the active noise cancellation 
also at the earpiece. To activate this feature, select
 > 
Settings > Settings and Phone > Call > Noise 
cancellation. 
Active noise cancellation is not available if handsfree mode 
or the loudspeaker is active. 
For the best noise 
cancellation, hold 
the device with the 
earpiece to your 
ear and the main 
microphone (1)
towards your 
mouth. Do not 
cover the 
microphone (2) at 
the back of the device. 
Video calls 
Make a video call 
To make a video call, enter the phone number or select the

video back to you, a still image is shown instead. To define 
the still image sent from your device instead of video, select

Settings > Settings and Phone > Call > Image in 
video call.

select Options > Disable > Sending audio, Sending 
video, or Sending aud. & video. 
To adjust the volume of an active video call, use the volume 
keys.

loudspeaker. To mute the loudspeaker and use the earpiece, 
select Options > Activate handset. 
To swap the places of images, select Options > Swap 
images. 
To zoom the image on the display, select Options > Zoom 
and scroll up or down. 
To end the video call and make a new voice call to the same
