Maintaining Your 901®Series VI Speaker System
Cleaning your speakers
If your 901® speakers have a painted surface, clean with a soft damp cloth. If necessary, use a mild detergent such as dish soap. If the speakers have a wood veneer finish, clean them with wood furniture polish. You may vacuum the speaker grille panels carefully, if necessary.
Do not use any sprays near the system. Do not use any solvents, chemicals, or cleaning solutions containing alcohol, ammonia, or abrasives. Do not allow liquids to spill into any openings.
Troubleshooting
If you have a problem with your 901 Series VI speakers or 901 active equalizer, turn off the re- ceiver or amplifier before you proceed. Then check all the connections between the speakers, receiver, and active equalizer. Correct any wiring problems before you follow the guidelines below. Problems are more likely to originate with equipment other than speakers, so you may also want to refer to your receiver or other component owner’s guides.
