Maintaining Your Acoustimass

The cabinets of your Acoustimass 5 Series III speaker system may be cleaned with a soft

damp cloth. Do not use any sprays near the system or allow liquids to spill into any open-

ings. Also, do not use any solvents, chemicals, or cleaning solutions containing alcohol,

ammonia, or abrasives.

The grille assemblies on the cube arrays may be carefully vacuumed if necessary. Please

note that the drivers are located directly behind the grille cloth, and are easily damaged if

reasonable care is not taken.

What to do

• Turn off the receiver or amplifier. Check the wiring that connects the cube array to the

Acoustimass module, and the wiring that connects the module to the receiver or amplifier.

If no problem is found, disconnect the speaker wires at the back of the receiver. Recon-

nect only the wire from the channel in question to the opposite channel at the receiver.

Turn the balance control completely to that channel, and turn the power on. If the cube

array now works properly, the problem is in the receiver or amplifier.

• Do not connect the other cube array to the defective channel. It could damage your

speaker system.

• Turn off the receiver or amplifier and disconnect the Acoustimass 5 speaker system.

Reconnect the system to another receiver known to be working properly. If the

Acoustimass 5 system now works properly, the problem is not in the speaker system.

• If this is the case, you should check all user accessible fuses on your receiver or amplifier

(see the appropriate owner's guide for help). If the fuses blow again, have the unit checked

by qualified personnel.

• If trouble persists in your Acoustimass 5 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.
