Program Calculator

The DF-320TM desk calculator has a large, 3-line, 12-digit, angled display that is easy to read. With 3 lines, you see your calculation as well as the result. The calculator features functions for tax, change and time (hours, minutes, seconds) calculations, currency conversions, as well as calculations of cost, selling price and margin. It has an independent, 3-key memory, decimal selector and 3-digit comma separators. It is solar-powered with battery back-up. It has no technical programming features. If you have your manual (which doesn't seem to be available online), the instructions should be easy to follow the operation of your calculator.
