Warnings

After clearing the memory your calculator will be normally functional. However, don't forget the following two important facts:

• Before calculating anything including angles verify the angle unit setting. Select degrees or radians.
• Clearing memory can switch off certain special functions. If you intend to calculate correlation coefficient r (called also Pearson product-moment correlation coefficient, see: Bivariate statistics), you'll have to switch DiagnosticOn (use the CATALOG button to find it).
