water spray, juice, coffee, steam, perspiration, etc. will also 
cause malfunction.
  Clean with a soft, dry cloth. Do not use solvents or a wet cloth.
  Do not drop the calculator or apply excessive force.
  Never dispose of batteries in a  re.
  Keep batteries out of the reach of children.
  This product, including accessories, may change due to up-
grading without prior notice.
