clean

using

a

soft

cloth

dampened

with

a

mild

detergent.

You

can

also

vacuum

the

cloth

grille

on

each

speaker,

but

apply

very

little

pressure

to

prevent

damaging

the

driver

behind

the

grille.

No

other

regular

maintenance

is

required.

Troubleshooting

If

you

have

a

problem

with

your

1.

Turn

off

the

amplifier

or

receiver

and

check

all

the

connections

between

the

speakers

and

amplifier

or

receiver.

Refer

to

Figure

4

on

page

2.

Check

your

amplifier

or

receiver

owner's

guide,

since

other

components

may

be

the

cause

of

the

problem.

3.

Use

the

chart

below

as

troubleshooting

guidelines.

If

they

do

not

solve

your

problem,

contact

your

arrange

for

doesn't

play

or

sounds

distorted.

Defective

amplifier

or

receiver

channel,

or

defective

speaker.

Disconnect

the

Then

switch

them,

connecting

the

right

speaker

cord

to

the

left

speaker

and

the

left

speaker

cord

to

the

right

speaker.

If

the

originally

faulty

speaker

now

plays

properly

and

the

other

does

not,

one

channel

i

the

amplifier

or

receiver

is

probably

defective.

If

the

original

speaker

still

does

not

play

properly,

call

Bose

or

your

retailer

to

arrange

for

service.

Both

from

the

speakers.

Reconnect

the

speakers

to

another

amplifier

or

that

is

working

properly.

High

sound

volume

drops

suddenly.

The

automatic

system

protection

circuit

has

acti-

vated

to

protect

the

speakers

from

electrical

stress

or

overload.

Lower

the

volume.

If

it

returns

to

normal,

your

speakers'

automatic

protection

circuit

caused
