Noise cancellation button
See figure 1 on page 1
Your H780 headset has a noise cancellation button that enables you to hear 
the difference of dual microphone noise cancellation.
The dual noise cancellation feature is on by default whenever H780 is 
powered on. Noise cancellation is always on each time a new call is received 
or placed. To turn the feature off (or back on), tap the Noise Cancellation 
button. The button only works during an active call.
