1 MAIN : Use this mode for basic calculations, including scientific
calculations and Base–n calculations.
2 STAT : Use this mode to perform single–variable and
paired–variable statistical calculations and regression
calculations.
3 CPLX : Use this mode to perform complex number calculation.
4 RESET : Use this mode to perform reset operation.
5 ENG : Use this mode to allow engineering calculations utilizing
engineering symbol.
Give " 2 STAT " as an example :
Method 1 : Press [ MODE ] and then scroll through the menus using
[
] or [ 2nd ] [
] until " 2 STAT " is underlined,
then enter the desired mode by pressing [=].
Method 2 : Press [ MODE ] and then key in directly the number of
the mode, [ 2 ] , to enter the desired mode immediately.
Using " 2nd " Keys
When you press [ 2nd ], the " 2nd " indicator shown in the display is to
tell you that you will be selecting the second function of the next key
you press. If you press [ 2nd ] by mistake, simply press [ 2nd ] again to
remove the " 2nd " indicator.
Corrections
If you have made a mistake when entering a number (but you have not
yet pressed an arithmetic operator key), just press [ CE ] to clear the
last entry then input it again, or delete individual digits by the
backspace key [
], or clear all entry by [ ON/C ].
After making corrections, input of the formula is complete, the answer
can be obtained by pressing [=]. You can also press [ ON/C ] to clear
the immediate results completely (except clearing memory). If you
press the wrong arithmetic operation key, just press the correct key to
replace it.
Undo function
The unit offers an undo function which allows you to undo some of the
errors you just have made.
When a character which is just deleted by [
], an entry which is just
cleared [ CE ], or which is just cleared by [ ON/C ], the "
" indicator
shown in the display is to tell you that you can press [ 2nd ] [
] to
cancel the operation.
