Please read and save this guide
Please read this guide carefully. Save this guide for future reference and make it easily accessible for passengers and
third parties who use this headset.
• Switch to an alternate communications method in the event of a headset issue.
In the unlikely event of any headset issue or failure in the passive noise reducing mode, switch to an alternate

urn the headset o if it emits any loud noise.
As with any complex electronic device, it is possible for this headset to fail during operation. Symptoms of failure,
which may include loud tones, distortion, feedback squeals and loss of communications signal in the headset, can
occur in either the Acoustic Noise Cancelling

power switch. The headset will continue to provide communications in the passive noise-reducing mode. If the
problem persists, see “Troubleshooting” on page 44.
• Be aware of sound dierences while wearing the headset.
With the headset’s active and passive noise reduction, typical aircraft sounds (such as engines, propellers, warning
alarms, and other sound sources) may not sound familiar. Make sure you can hear and recognize these sounds when
using the headset while operating any aircraft.
• Do NOT make phone calls while piloting.
Do not use the headset for telephone calls during flight operations.

This control aects the strength of the communications signal coming into the headset. Make sure you can
understand critical communications even with Acoustic Noise Canceling mode turned o. In this case, you may need
to turn up the aircraft communications system volume. In passive mode, the volume controls on the control module
will automatically be set to maximum volume. For additional volume control, use the intercom or radio volume

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
Cancellation” on page 19. If it persists, see “Troubleshooting” on page 44.
A low rumbling sound or frequent, brief losses of noise cancellation may indicate
an improper fit or blocked earbud ports. See “Choose the correct StayHear®+ tips”
on page 14 for information on proper fit or “Clean the headset” on page 40 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.

Two for audio
One for power
One for ground
Two for audio shields
Audio and microphone wires should be connected to the back of the existing
microphone and headphone jacks, leaving existing jacks intact for use with
conventional headsets. This is usually the fastest installation method.
CAUTION: Do NOT use excessive force or bend the installed connector. This may
damage or break internal solder joints.
NOTE: The aircraft panel connector cannot be installed in an audio system using
transformer-coupled audio outputs. Contact Bose technical support.
