Bose AM262840 User Manual

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. Do not use any solvents, chemicals, 
or cleaning solutions containing alcohol, ammonia, or abrasives. Do not allow liquids to spill into any open-
ings. Do not use any sprays near the amplifier.

Although some Bose

®

 speakers are designed and tested to stand up to outdoor weather conditions, 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 connections. 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.
