WARNINGS/CAUTIONS
• Do NOT use the headphones at a high volume for any extended period.
– To avoid hearing damage, use your headphones at a comfortable, moderate volume level.
– Turn the volume down on your device before placing the headphones in/on your ears, then turn the volume up
gradually until you reach a comfortable listening level.
• Do NOT use your headphones while driving for phone calls or any other purpose.
• Do NOT use the headphones with noise cancelling on at any time the inability to hear surrounding sounds may
present a danger to yourself or others, e.g., while riding a bicycle or walking in or near traffic, a construction site or
railroad, etc.
– Remove the headphones, or use the headphones with noise cancelling off and adjust your volume, to ensure you
can hear surrounding sounds, including alarms and warning signals.
– Be aware of how sounds that you rely on as reminders or warnings may vary in character when using the
headphones.
• Do NOT use the headphones if they emit any loud unusual noise. If this happens, turn the headphones off and contact
Bose customer service.
• Remove headphones immediately if you experience a warming sensation or loss of audio.
• Do NOT use mobile phone adapters to connect headphones to airplane seat jacks, as this could result in injury or
property damage due to overheating.
• Do NOT use the headphones as aviation communication headsets except in case of emergency.
– 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 headphones are not engineered for noise conditions, altitude, temperature or other environmental conditions
common in non-commercial aircraft, resulting in possible interference to critical communications.
