•You cannot make changes to the angle unit or other display format (Disp)

settings while the calculator is in the BASE Mode.

•The COMP, CMPLX, SD, and REG modes can be used in combination

with the angle unit settings.

•Be sure to check the current calculation mode (SD, REG, COMP, CMPLX)

and angle unit setting (Deg, Rad, Gra) before beginning a calculation.

kInput Capacity

•The memory area used for calculation input can hold 79 “steps.” One step

is taken up each time you press a number key or arithmetic operator key

( +, ,, -, \ ). A A or p key operation does not take up a step, so

inputting A D, for example, takes up only one step.

•You can input up to 79 steps for a single calculation. Whenever you input

the 73rd step of any calculation, the cursor changes from “_” to “k” to let

you know memory is running low. If you need to input more than 79 steps,

you should divide your calculation into two or more parts.

•Pressing the g key recalls the last result obtained, which you can use in

a subsequent calculation. See “Answer Memory” for more information

about using the g key.

kMaking Corrections During Input

•Use e and r to move the cursor to the location you want.

•Press [ to delete the number or function at the current cursor position.

•Press A K to change to an insert cursor t. Inputting something while

the insert cursor is on the display inserts the input at the insert cursor

position.

•Pressing A K, or < returns to the normal cursor from the insert cursor.

kReplay Function

•Every time you perform a calculation, the replay function stores the

calculation formula and its result in replay memory. Pressing the [ key

displays the formula and result of the calculation you last performed.

Pressing [ again back steps sequentially (new-to-old) through past

calculations.
