Your EC-443 Solar Powered Calculator is an example of superior design and
craftsmanship.  The following suggestions will help you care for the
calculator so you can enjoy it for years.

 Keep the calculator dry.  If it gets wet, wipe it dry immediately. 
 Liquids can contain minerals that can corrode the electronic circuits.

 Use and store the calculator only in normal temperature environments. 
 Temperature extremes can shorten the life of electronic devices, and
 distort or melt plastic parts.

 Handle the calculator gently and carefully.  Dropping it can damage
 circuit boards and cases and can cause the calculator to work improperly.

 Keep the calculator away from dust and dirt, which can cause premature
 wear of parts.

 Wipe the calculator with a damp cloth occasionally to keep it looking
 new.  Do not use harsh chemicals, cleaning solvents, or strong detergents
 to clean the calculator.

Modifying or tampering with the calculator's internal components can cause
a malfunction and might invalidate its warranty.  If your calculator is
not performing as it should, take it to your local Radio Shack store for
assistance.
