MAINTENANCE  
Your Optimus AMX-10 Stereo Amplified Speakers are an example of superior de-  
sign and craftsmanship. The following suggestions will help you care for the speak-  
ers so you can enjoy them for years.  
Keep the speakers dry. If they get wet, wipe them dry immediately.  
Liquids might contain minerals that can corrode the electronic cir-  
cuits.  
Use and store the speakers only in normal temperature environ-  
ments. Temperature extremes can shorten the life of electronic de-  
vices, damage batteries, and distort or melt plastic parts.  
Keep the speakers away from dust and dirt, which can cause prema-  
ture wear of parts.  
Handle the speakers gently and carefully. Dropping them can dam-  
age the circuit boards and can cause the speakers to work improper-  
ly.  
Wipe the speakers with a damp cloth occasionally to keep them look-  
CLEANER  
ing new. Do not use harsh chemicals, cleaning solvents, or strong de-  
tergents to clean the speakers.  
Modifying or tampering with the speakers’ internal components can cause a mal-  
function and might invalidate the warranty. If your speakers are not performing as  
they should, take them to your RadioShack store for assistance.
