Before Using the Calculator
Check the current Calculation Mode
Be sure to check the status indicators that indicate the
current calculation mode (COMP, STAT, TABLE), display
formats setting, and angle unit setting (Deg, Rad, Gra).
Return to initial setup
Press (YES) to return the initial
calculator setup:
Calculation mode : COMP
Input/Output Format : Maths
Angle unit : Deg
Display Digits : Norm 1
Fraction Display Format : d/c
Statistical Data Input : OFF
Decimal Point format : Dot
This action will not clear the variable memories.
Initialize the calculator
When you are not sure of the current calculator setting, you
are recommended to initialize the calculator (resets
calculation mode to "COMP", angle unit to "Degree", clears
replay and variable memories, and resets LCD contrast) by
performing the following key operations:
(All) (YES) .

Inputting Expressions and Values
Input Capacity
F-789SGA allows you to input a single calculation with up to 99
bytes. Normally, one byte is used each time you press one of
the numeric keys, arithmetic keys, scientific function keys or
. Some functions require 4 – 13bytes. , , and the
direction keys will not use up any bytes.
When the remaining input capacity is less than 10bytes, the
input cursor will change from “ ” to “ ” signaling that the
memory is running now.
Input Editing
New Input begins on the left of display. When the input data
is more than 15 characters (Line Mode) / 16 characters
(Math mode), the line will scroll to the right consecutively.
You can scroll back to the left by using and to review
the input.
In Line mode, press to let the cursor jump to the
beginning of input, press to jump to the end.
In Mathematics mode, press to let the cursor jump to the
beginning of input when it is at the end of the input
calculation. Or press to let the cursor jump to the end of
input when it is at the beginning of the input calculation.
Omit the multiplication sign and final close parenthesis.

Insert and Overwrite Input mode
In Line mode, you can use INSERT or overwrite mode for
inputting.
- In Insert mode (Default input mode), the cursor is a
vertical flashing line “ ” for inserting a new character.
- In Overwrite mode, press key to switch the cursor
to a flashing horizontal “ _ ” and replace the character at
the current cursor position.
In Mathematics mode, you can only use the Insert mode.
Whenever the display format changes from Line mode to
Mathematics mode, it will automatically switch to the Insert mode.
Deleting and Correcting an Expression
In Insert mode: Move the cursor to the right of the character or
function that needs to be deleted, then press .
In Overwrite mode: Move the cursor under the character or
function being deleted, then press .
Example: 1234567 + 889900

NOTE
(1) Some input expressions cause the height of a
calculation expression to be greater than one display
screen. Maximum input capacity: 2 display screens
(31 dots x 2).
(2) Calculator memory limits how many functions or
parentheses can be input in any single expression. In
this case, divide the expression into multiple parts
and calculate separately.
(3) If part of the expression you input is cut off after
calculation and in the result display screen, you can

When a calculation contains an argument that is a negative
number, the negative number must be enclosed within the

Calculation Stacks
This calculator uses memory areas, called “stacks”, to
temporarily store numeric value (numbers) commands (+, –,
x…) and functions according to their precedence during
calculations.
The numeric stack has 10 levels and the command stack has
128 levels. A stack error [Stack ERROR] occurs whenever
you try to perform a calculation that exceeds the capacity of
stacks.
Calculations are performed in sequence according to “Order
of Operations”. After the calculation is performed, the stored
stack values will be released.
Error Messages and Error Locator
The calculator is locked up when an error message is shown on
the display indicating the cause of the error.
Press to clear the error message, then return to the
initial display of the latest mode.
Press or to display the input expression with the
