7 T wo-line Display The two-line displa y makes it possible to view both the calculation form ula and its result at the same time. • The upper line shows the calculation f ormula. • The lower line sho ws the result. A separator symbol is displa yed e v er y three digits when the integer par t of the mantissa has more than three dig- its.
8 •P r e ssing the F ke y more than twice displa ys additional setup screens. Setup screens are described in the sec- tions of this manual where the y are actually used to change the calculator setup .
9 k Making Corrections During Input •U s e e and r t o mo v e t he cursor to the location y ou w ant. •P r e ss [ to delete the number or function at the current cursor position. •P r e ss A K to change to an insert cursor t . Inputting something while the inser t cursor is on the displa y in- ser ts the input at the insert cursor position.
