Maintaining Your Acoustimass

Clean the cabinets of your Acoustimass

mild detergent such as dish soap. Do not use any solvents, chemicals, or cleaning solutions

containing alcohol, ammonia, or abrasives. Do not allow liquids to spill through the speaker

grilles or enter the Acoustimass module.

You can vacuum the speaker grilles. To avoid damaging the drivers located directly behind

the grille cloth, use light pressure only.

If you have a problem with your Acoustimass 3 speaker system, turn off the amplifier or

receiver and check all the connections between the cube speakers, the module, and amplifier

or receiver. Since problems are likely to originate with components other than speakers, you

may want to refer to your amplifier or receiver owner's guide.

What to do

• Disconnect both speaker cables from the amplifier or receiver. Reconnect the cable from

the bass module's L INPUTS to the amplifier or receiver's RIGHT speaker terminals.

Set the amplifier or receiver's balance control all the way to the right and turn on the power.

• If the left cube speaker now plays properly, your amplifier or receiver's left speaker channel

is probably defective.

CAUTION: DO NOT connect the other cube speaker to the channel in question. If the

channel is defective, it could damage your Acoustimass 3 system.

• Follow the above steps, reconnecting the cable from the module's R INPUTS to the

amplifier or receiver's LEFT speaker terminals.

• Disconnect the amplifier or receiver from the bass module. Reconnect the module to

another amplifier or receiver that is working properly.

• If the system now works, the problem is in your amplifier or receiver. Refer to your receiver

or amplifier owner's guide for further suggestions.

• If trouble persists in your Acoustimass 3 speaker system, contact your authorized Bose

dealer who will verify any defects and arrange for service by an authorized agency or by the

Bose factory. Bose will make every effort to remedy any problem within the terms of the

warranty at minimum inconvenience to you.
