Operations to clear the display depend upon the type of display being shown:

Text :
Pressing the
key causes a cleared text display to appear if pressed during a graph display.
1.4.8 Corrections
To make corrections in a formula that is being input, use the and keys to move the position of the
error and press the correct keys.
*** If, after making corrections input of the formula is complete, the answer can be obtained by pressing
. If, however, more is to be added to the formula, advance the cursor using the key to the end
of the formula for input.
●
If an unnecessary character has been included in a formula, use the and keys to move to the
position of the error and press the
key. Each press of
will delete one command (one
step).
●
If a character has been omitted from a formula, use the and keys to move to the position where
the character should have been input, and press
followed by the key. Press
and insertions can be subsequently performed as desired.
*** When
are pressed, the letter at the insertion position is surrounded by “[ ]” and blinks.
The insert function is activated until you press , , or
or until you perform
again.

5) Even though memory has not been expanded, a memory name such as Z [2] is used.
6) Input errors are made. (Ex.
)
7) When improper arguments are used in commands or functions that require arguments.
( i.e. Input of an argument outside of the range of 0~9 for Sci or Fix.)
The following error messages will be displayed for the operations noted above:
1~3 Ma
ERROR
4 Stk
ERROR
5 Mem
ERROR
6 Syn
ERROR
7 Arg
ERROR
Besides these, there are an “Ne ERROR” (nesting error) and a “Go ERROR”. These errors mainly occur
when using programs.
1.4.6 Number of input characters
This unit features a 127 steps area for calculation execution.
One function comprises one step. Each press of numeric or [+] [-] [x] and [
÷
] keys comprise one step.
Though such operations as
Require two keys operations, they actually comprise only one
function and, therefore, only one step. These steps can be confirmed using the cursor. With each press of
the [ ] or [ ] key the cursor is moved one step.
Input characters are limited to 127 steps. Usually the cursor is represented by a blinking “_”, but once the
121
st
step is reached the cursor changes to a blinking “)”. If the “(” appears during a calculation, the
calculation should be divided at some point and performed in two parts.
*** When numeric values or calculation commands are input, they appear on the display window from the
left. Calculational results, however, are displayed from the right.
1.4.7 Graphic and text displays
This unit has a graph display for production of graphs, as well as a text display for production of formulas
and commands. These two types of display contents are stored independently of each other.
Switching between graph and text displays is performed using the
key. Each press of
switches from the current type of display to the other.
