CARE AND MAINTENANCE
Your Earthquake Stereo 4-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 parametric 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.
Handle the parametric 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.
Use and store the parametric equalizer only in normal
temperature environments. Temperature extremes can shorten
the life of electronic devices and warp or melt plastic parts.
Keep the parametric equalizer away from dust and dirt, which can
cause premature wear of parts.
