TAP CONTROL FOR TALK-THROUGH COMMUNICATION
When you need to focus on interpersonal communication coming from a specific 
 direction, you can automatically set noise cancellation to LOW in one earcup.
NOTES: 
•  By default, the TAP CONTROL operation switch is set to OFF. 
•  Tap Control is available only when the Acoustic Noise Cancelling (ANC) switch is in 
the HIGH or MED position.
•  Tap Control is disabled during extreme levels of  ambient noise to ensure proper 
noise reduction performance and intercom communication quality. However, you 
can still set the noise cancellation level to LOW in both earcups using the Acoustic 
Noise Cancelling (ANC) switch (see page 23).
1.  Make sure the Acoustic Noise Cancelling (ANC) switch is in the HIGH or  
MED position. 
2.  Inside the control module battery compartment, set the TAP CONTROL switch to 
ON. See “Change the operation switches” on page 28.
3.  Firmly double-tap the outside of the earcup.
