Bose A30 AVIATION HEADSET Manual De Instrucciones página 3

• 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 54.
• 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.
• Do NOT make phone calls while piloting.
Do not use the headset for telephone calls during flight operations.
• Make sure your aircraft communications system volume control is easily accessible.
This control affects the strength of the communications signal coming into the headset. Make sure you can
understand critical communications even with Acoustic Noise Cancelling mode turned off. 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 control. If your headset is aircraft powered, connect the headset to the aircraft power sources only as
described in "Aircraft Connectors" on page 34.
• Make sure portable devices do not interfere with the aircraft's navigation and communication systems.
Reference FAA AC 91.21-1D, or later revision, for installation approval.
It is the pilot's responsibility to ensure that portable devices do not interfere with the aircraft's navigation and
communication systems, as well as to determine if the portable device is suitable for use with the headset.
• Use AA (LR06) batteries, alkaline preferred.
Alkaline batteries are recommended for best results. Other battery chemistries may yield different results. Battery
life may differ and battery life indication may not be accurate. Properly dispose of used batteries.
• Do NOT repair the headset yourself.
Contact the Bose organization in your country/region for specific care, return and shipping instructions.

• Do not use the headset with a helmet or as part of a crash protection system.
The headset is not intended for such use, and has not been certified for crash protection. Dismantling, reassembly
or modification of the headset, or any part, for use in a helmet or other crash protection system could result in
severe bodily injury and such unauthorized use will void the limited product warranty.
• Do NOT immerse the headset or any parts in water or any other liquid.
See "Clean the headset" on page 48 for cleaning instructions.
• Keep the earcup free of debris.
Proper headset operation requires that the headset acoustic and microphone openings located on the outside of
each earcup are kept free of debris to ensure clear communications. See "Clean the headset" on page 48 for
cleaning instructions.
