R AAA (IEC LR03) alkaline battery + ­ Wearing the headphones As you put on the headphones, observe the markings that identify the left (L) and right (R) earcups. Adjust the headband so it rests gently on top of your head and the earcup cushions fit comfortably around your ears. 3 Using Your Headphones English English For noise reduction and audio Use the supplied headphones cord to enjoy both audio and noise reduction. Please note that the LEVEL switch on the plug is used to adjust the output volume of different audio sources. 1. Set the LEVEL switch on the headphones cord to appropriate setting for your audio source. LEVEL switch. L LO Typically used for airline audio systems or audio devices that use A/C power. HI Typically used for battery-powered audio devices (CD/DVD or MP3/ digital audio players) and personal computers. Headphones cord Note: The HI and LO settings have no affect on noise reduction. 2. Insert the headphones cord into the opening on the left (L) earcup. Push the plug in so it is flush with the side of the earcup. 3. Connect the headphones cord to your audio source. Refer to "Connecting to portable and home audio devices" on page 5. 4. Put on the headphones and turn on the power switch. 5. Use the volume control on your audio source to make further volume adjustments. For noise reduction only If you plan to use them for noise reduction only, simply put on the headphones and turn on the power switch, located on the right earcup. The headphones cord is not required. 4 Using Your Headphones Connecting to portable and home audio devices The 3.5 mm plug on the headphones cord allows you to connect your headphones to a variety of audio devices that use a single 3.5 mm output jack such as a CD, DVD, MP3/digtal audio player, or personal computer. Set the LEVEL switch to HI and plug the headphones cord directly into the 3.5 mm output jack. To connect to a home stereo system that has a ¼ in (6.3 mm) stereo output jack, use the the ¼ in (6.3 mm) stereo adapter plug included with your headphones. Set the LEVEL switch to LO. Plug the headphones cord into the adapter plug and insert it into the output jack on your stereo system. English English Connecting to airline audio systems The audio output connections on airline audio systems vary, but they typically have dual or single 3.5 mm output jacks. Note: Airline audio may not equal the high quality audio you experience from a home stereo or portable source. Connecting to dual output jacks Set the LEVEL switch to LO. Plug the headphone cord into the dual-plug adapter and insert it into the dual output jacks. Connecting to a single output jack Set the LEVEL switch to LO. Plug the headphone cord into the adapter and insert it into the single output jack. The LO setting of the LEVEL switch lowers the volume levels of strong audio output signals which are common on airline systems. If you find that the volume level is too low, set the LEVEL switch to HI. 5 Care and Maintenance English English Folding the earcups for storage QuietComfort 2 Acoustic Noise Cancelling headphones feature rotating earcups that fold flat for easy, convenient storage. The earcups rotate in one direction only. ® ® L R CAUTION: Incorrectly rotating the earcups can damage the headphones. Reattaching earcup cushions The earcup cushions are held in place by a mounting flange. This flange snaps under small tabs located around the inside rim of the earcup. If an earcup cushion becomes partially or completely detached, push its mounting flange back into the earcup. Then use your finger or thumb to press around the edge of the mounting flange, making sure it snaps into place all the way around the earcup. 6 Care and Maintenance Battery replacement Although it varies by usage, battery life averages 35 hours. With the headphones turned on, the battery light indicator will flash when there are approximately 8 hours of battery life remaining. When a replacement is needed, use 1 AAA alkaline battery (IEC LR03). Tilt the top of the right earcup inward to gain access to the battery compartment. R English English + ­ Note: You can use rechargeable batteries (NiMH, composed of nickel metal hydride, are recommended). They average half the life of alkaline batteries. However, the low battery indicator light is not set for such batteries and will not be a reliable indicator of their remaining battery life. Replacement parts and accessories You can purchase accessories from your Bose dealer, on the internet (www.Bose.com), or by placing an order over the phone.

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 that are common to many propeller-driven aircraft may impair the user's ability to receive incoming audio communications, particularly during takeoff and climb out when noise levels are high. · The QuietComfort 2 headphones are not engineered for the altitude, temperature or other environmental conditions common in non-commercial aircraft, resulting in possible interference to critical communications. For pilots, Bose offers a communication headset which is 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 non-commercial 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.
