Car Stereo Frequency Equalizer (120-1962) Care and Maintenance Faxback Doc. # 18247 Your Realistic Car Stereo Frequency Equalizer is an example of superior design and craftsmanship. The following suggestions will help you care for the equalizer so that you can enjoy it for years. Keep the equalizer dry. If it does get wet, wipe it dry immediately. Liquids contain minerals that can corrode electronic circuits. Use and store the equalizer only in normal temperature environments. Temperature extremes can shorten the life of electronic devices, dam- age batteries, and distort or melt plastic parts. Handle the product gently and carefully. Dropping it can damage the circuit boards and can cause the equalizer to work improperly. Wipe the equalizer with a dampened cloth occasionally to keep the equalizer looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the equalizer. Modifying or tampering with the equalizer's internal components can cause a malfunction and might invalidate the equalizer's warranty and void your FCC authorization to operate it. If the equalizer is not working as it should, take it to your local Radio Shack store so that our personnel can assist you or arrange for service if needed.
