Care and Maintenance  
Your Earthquake Stereo 7-Band Graphic Equalizer is an example of superior design and  
craftsmanship. The following advisories will help you care for your equalizer so you can  
enjoy it for years to come.  
Keep the graphic equalizer dry. If it gets wet, wipe it dry immediately.  
Liquids contain minerals that can corrode electronic circuits. Additionally  
liquids can cause severe electrical shock.  
Use and store the graphic equalizer only in normal temperature  
environments. Temperature extremes can shorten the life of electronic  
devices and warp or melt plastic parts.  
Handle the graphic equalizer gently and carefully. Dropping it can  
damage the circuits or cause components to break or become loose.  
These kind of actions can cause the units to work poorly or improperly.  
Keep the graphic equalizer away from dust and dirt, which can cause  
premature wear of parts.  
Earthquake products are capable of generating high sound pressure levels. You  
CAUTION:  
should exercise caution when operating these products. Long term exposures to  
high levels of sound pressure will cause permanent damage to your hearing.  
Sound pressure levels exceeding 85dB can be dangerous with constant exposure. Set your audio  
system to a comfortable loudness level. Earthquake Sound Corporation does not assume liability  
for damages resulting from the direct use of Earthquake amplifiers or other Earthquake products ,  
and urges users toplay their music at moderate listening levels.
