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 usetheheadphonesforaudio,ﬁrstnoticethesettingson

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 per-

sonal or laptop computer, or home stereo.The maximum

input voltage is 9Vrms.

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:

A single, 3.5 mm jack (on most portable

sources) – use the single plug.No adapter needed.

Two 3.5 mm jacks – use the dual plug adapter.

One 3.5 mm jack and one power jack – use the

single plug in the 3.5 mm jack (the larger one).

The smaller jack does not need a connection.

One power jack and two 3.5 mm jacks – use

the dual plug adapter for the two 3.5 mm

jacks.The power jack does not need a connection.

One 6.3 mm jack (for home stereos) – use the

6.3 mm stereo phone adapter.

Note:

udio 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.

Care

AM257565_00 _V.pdf May 13, 2003

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.

Replacement parts and accessories

You can order parts and accessories, as listed below, by

contacting Bose

Other needs

These headphones are not engineered to meet the

needs of pilots or to meet civil aviation authority

standards for aviation communications.

For that purpose, Bose offers the Aviation Headset ,

which features a microphone with the appropriate power

and intelligibility for transmission of ﬂight information.It is

engineered to withstand the altitude and temperature

conditions common in non-commercial aircraft.

For information on the Bose®Aviation Headset ,

contact Bose Corporation by calling 1-508-766-1099

or +31(0)299-390777.

Cautions

Long-term exposure to loud music may cause hearing

damage.It is best to avoid extreme volume when using

these headphones, especially for extended periods.

Do not use these headphones when operating a motor

vehicle on a public road, or where the inability to hear

outside sounds may present a danger to the user or

others.

Sounds that you rely on as reminders or warnings may

have an unfamiliar character when you are using the

headphones.Be aware of how these sounds vary in

character, so you can recognize them as needed.

Do not drop, sit on, or allow the headphones to be

immersed in water.
