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.

USING YOUR HEADPHONES

• 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. There are no cable connections required for this use.
• To use the headphones for audio, first notice the settings on the audio attenuator shown below.
• These Hi and Lo settings are used to adjust the output volume of different audio sources. “Lo” is typically used for airline audio or audio devices that use A/C power. “Hi” is typically used for battery-powered audio devices.
• NOTE: Hi and Lo settings have no effect on noise reduction.
• Select the appropriate setting for the sound source you will use. Then insert the audio attenuator into the opening on the left (L) earcup and press it in so it is flush with the side of the earcup.
• As soon as you connect the headphone plug to your audio source, you are ready to put on the headphones and turn on the power switch to enjoy both audio and noise reduction. Use the volume control on the selected audio source to make additional volume adjustments.

CONNECTING TO AN AUDIO SOURCE

• You can use the headphones with a variety of audio sources: airline audio, a CD, DVD or MP3 player, a personal or laptop computer, or home stereo. The maximum input voltage is 9 Vrms.
• To make the connection, insert the headphone plug into the jack on the audio source you will use.
• Notice the jack configurations on the left in the chart below. Instructions on the right tell you how to connect to each type of jack:
• NOTE: Audio jack configurations on airplanes vary. Also, airline audio may not equal the high quality audio you can get from a home stereo or a portable source.

FOLDING THE EARCUPS FOR STORAGE

QuietComfort® 2 Acoustic Noise Cancelling® headphones feature rotating earcups that fold flat for easy, convenient storage. They rotate in one direction only.

NOTE: 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.

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 5 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.

NOTE: You can use rechargeable batteries (NiMH, com- posed 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.
