Maintaining Your Lifestyle® Stereo Amplifier

Cleaning the amplifier

CAUTION: Disconnect the power cord from the AC outlet before cleaning.

The amplifier, which is designed only for indoor use, may become dusty over time. To clean the amplifier, use only a soft, dry cloth to remove dust from the outside of the enclosure. You may use a brush attachment on a vacuum cleaner to clean the hard-to-reach areas. DO NOT use any solvents, chemicals, or cleaning solutions containing alcohol, ammonia, or abrasives.

Protecting outdoor wiring

Although some Bose® speakers are designed and tested to stand up to outdoor weather con- ditions, the bare ends of the speaker wire can be affected by exposure to the elements. This is especially true of salt water exposure.

You may use a silicone caulking material, such as RTV adhesive, to protect speaker wire con- nections. It is commonly available at hardware stores. If you do use caulking, apply it only after the wires are connected and the knobs tightened down. Check the caulking annually, and re-apply as needed.

Troubleshooting

If you have a problem operating your Lifestyle® system after installing the Lifestyle® stereo amplifier, follow the guidelines below. For additional help, see the troubleshooting information in your system owner’s guide. If the problem still exists, contact your Bose® dealer to arrange for service, or contact Bose Customer Service. Refer to the address list enclosed in the prod- uct packaging for correct phone numbers.
