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
communications method and use standard cockpit resource management skills to minimize distractions.
• Use the headset at a moderate volume level.
To avoid hearing damage, use the headset at a comfortable, moderate volume level. Limit the headset volume to
safe levels that do not interfere with your ability to hear informational sounds and warning alarms, such as stall
warnings or gear up, while piloting.
• Turn the headset off 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 mode (turned on) or in the passive mode (turned off). If the headset
emits any loud noise and the related loss of communications in the Acoustic Noise Cancelling mode, turn off the
power switch. The headset will continue to provide communications in the passive noise-reducing mode. If the
problem persists, see "Troubleshooting" on page 48.
• Be aware of sound differences 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.
