IMPORTANCE OF PROPER FIT
FIT THE HEADBAND
Proper fit is important both for comfort and optimal noise cancellation performance.
1. Locate the left Tand right Uicons inside the earcups to orient the
headset properly.
2. Place the headset on your head.
3. Adjust the headband so the ear cushions completely cover your ears.
NOTE: For best performance, make sure the ear cushions fit securely around your
ears so they create a seal.

CONDITIONS RELATED TO FIT
In very loud conditions, such as during takeo, you may experience a brief reduction
in noise cancellation as the headset compensates for a momentary pressure
change. If this continues when the sound level returns to normal, see “Acoustic Noise
Cancelling” on page 23. If it persists, see “Troubleshooting” on page 54.
A low rumbling sound or frequent, brief losses of noise cancellation may indicate
an improper fit or blocked earcup openings. See “Clean the headset” on page 48
for instructions on removing blockages.
During a long flight, you may feel a slight pressure point, which can be relieved by
adjusting the headband position.
SECURE THE CABLE AND CONTROL MODULE
The cable clips and control module holder secure the cable and control module to
your clothing, a safety harness, sun visor rail, or aircraft headset hook for quick and
easy access.
Cable clips
Squeeze the narrow end of the clip to open. Press the side button to release and
reposition the clip along the cable.

ACOUSTIC NOISE CANCELLING
Acoustic Noise Cancelling reduces unwanted noise, providing a clearer, more
lifelike audio performance. You can choose your noise cancellation level based on
your listening preferences and environment.
NOTE: When you receive a call, the headset remains at the current noise
cancellation level.
ACOUSTIC NOISE CANCELLING (ANC) SWITCH
Sets the noise cancellation level.
FUNCTION POSITION DESCRIPTION
HIGH
Maximum quiet and noise cancellation across the entire
spectrum. Best signal-to-noise ratio for radio and intercom
communications in loud aircraft.
MED
Consistent noise reduction across a wide range of
frequencies. Best for clear and comfortable noise
cancellation in typical jet aircraft.
LOW Best for improved interpersonal communication outside
of the intercom in quieter environments.
