Proper fit on your head is important both for comfort and optimal noise

reduction performance. Here are a few guidelines:

• Use the left (L) and right (R) markings above the earcups to orient the headset

properly.

• As you put the headset on, lightly grasp each earcup and adjust it so its

cushion is completely over your ear. You should feel an even, gentle pressure

all around each ear.

• Adjust the headband so it rests gently on top of your head.

Make your final adjustments with the headset powered on in a noisy

environment.

In very loud conditions, such as during takeoff, you may experience a brief

reduction in Acoustic Noise Cancelling

momentary pressure change. If the problem continues when the sound level

returns to normal, see "In case of difficulty" on page 27. If the problem persists,

contact Bose

Technical Support for assistance.

A low rumbling sound or frequent, brief losses of Acoustic Noise Cancelling

noise reduction may indicate an improper fit or blocked earcup ports. See

"Headset earcup openings" on page 23 for instructions on removing

blockages.

During a long flight, you may feel a slight pressure point, which can be relieved

by adjusting the headband position. Your experience with using the headset will

help establish a sense of how it should sound and feel.

Microphone placement is important for clear communications. With the

headset on your head, make these adjustments:
