• Avoid use and storage in areas subjected to large amounts of humidity and dust. Take care never to leave the calculator where it might be splashed by water or exposed to large amounts of humidity or dust. Such conditions can damage internal circuitry.
Two-line Display The two-line display makes it possible to view both the calculation formula and its result at the same time. • The upper line shows the calculation formula. • The lower line shows the result. A separator symbol is displayed every three digits when the integer part of the mantissa has more than three dig- its.
• In this manual, the name of the mode you need to enter in order to perform the calculations being described is indicated in the main title of each section. Example: Complex Number CMPLX Calculations Note! • To return the calculation mode and setup to the initial A B 2 defaults shown below, press (Mode)
• Pressing the key recalls the last result obtained, which you can use in a subsequent calculation. See “Answer Memory” for more information about using the key. k Making Corrections During Input • Use to move the cursor to the location you want.
