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.
