Bose QuietComfort 2 Owner's guide - Page 9

English Other Considerations WARNING: Except in case of emergency, Bose recommends that you NOT use these headphones as aviation communication headsets because: • No incoming audio will be heard with a discharged or improperly installed battery. This could result in the potential of missed communications while piloting an aircraft. • Extremely loud ambient noise levels common to many propeller-driven aircraft may impair your ability to receive incoming audio communications, particularly during takeoff and climb out. • The QuietComfort 2 headphones are not engineered for altitude, temperature or other environmental conditions common in non-commercial aircraft, resulting in possible interference to critical communications. QuietComfort® 2 headphones are designed for passenger use in air transport aircraft. They are not engineered to meet the needs of pilots or to meet civil aviation authority standards for communication headsets. For pilots, Bose offers a communication headset specifically designed to meet or exceed civil authority standards. It features a microphone with the appropriate power and intelligibility for transmission of flight information. It is also engineered to withstand the altitude and temperature conditions that are common in noncommercial aircraft. For more information on products for pilots, please contact Bose Corporation using the information supplied on the inside back cover of this owner's guide. 7
