Initial mode is COMP mode.
Calculator Set-up Menu
Press to enter the Calculator Set-up Menu;
press / for next / previous page.
To select the calculator input & output format [1] Maths
or [2] Line
[1] Maths – (Mathematics mode): The majority of
calculation input and output (e.g. Fraction, pi, square
root number) are shown in Mathematics textbook
format.
[2] Line – (Line mode): The majority
of calculation input and output are
shown in the lines format. And
“LINE” icon will be shown.

To select the angle unit [3] Deg, [4] Rad or [5] Gra
[3] Deg: Angle unit in Degree
[4] Rad: Angle unit in Radian
[5] Gra: Angle unit in Gradient
90º = radians = 100grads
To select display digit or notation [6] Fix, [7] Sci or [8] Norm
[6] Fix: Fixed Decimal, [Fix 0~9?] appears, specify the
number of decimal places by pressing [0] – [9].
Example: 220 ÷ 7 = 31.4286 (FIX 4)
= 31.43 (FIX 2)
[7] Sci: Scientific Notation, [Sci 0~9?] appears, specify
the number of significant digits by pressing [0] – [9].
Example: 220 ÷ 7 = 3.1429 x 101 (SCI 5)
= 3.143 x 101 (SCI 4)
[8] Norm: Exponential Notation, [Norm 1~2?] appears,
specify the exponential notation format by pressing [1] or
[2].
Norm 1: Exponential notation is automatically used for
integer values with more than 10 digits and decimal
values with more than TWO decimal points.
Norm 2: Exponential notation is automatically used for
integer values with more than 10 digits and decimal
values with more than NINE decimal places.
Example: 1 ÷ 1000 = 1 x 10-3 (Norm 1)
= 0.001 (Norm 2)
To select the fraction format [1] a b/c or [2] d/c
[1] a b/c: specify Mixed fraction display
[2] d/c: specify Improper fraction display

[2] Comma: specify comma format for Decimal point
result display
To Adjust Display contrast [5] CONT
See “Display Contrast Adjustment” section.
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
Pressing (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 (calculation
mode “COMP”, angle unit “Degree”, and clear reply and
variable memories), and LCD contrast by pressing
(All) (YES) .

Input Capacity
F-718S / F-719SG allows you to input a single calculation up
to 99 bytes. Normally, one byte is used as 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 input capacity is less than 10bytes, the input cursor
will change from “ ” to “ ” that notifying the memory is
running now.
Input Editing
New Input begins on the left of display. If input data are
more than 15 characters, 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 inputting, while will jump to the end.
In Mathematics mode, press to let the cursor jump to
the beginning of inputting while it is at the end of the
input calculation. Or press to let the cursor jump to
the end of inputting while it is at the beginning of the
input calculation.
INPUTTING EXPRESSIONS AND VALUES

9
Omit the multiplication sign and final close parenthesis.
*1. Omit multiplication sign (x)
- Input before an open parentheses : 1 x (2+3)
- Input before scientific functions that includes
parenthesis: 2 x cos(30)
- Input before Random number function
- Input before Variable (A, B, C, D, X, Y, M), π, е
*2. Scientific functions come with the open parenthesis.
Example: sin(, cos(, Pol(, LCM(…. You need to input the
argument and the close parenthesis .
*3. Omit the last close parenthesis before the , ,
, and (Only for F-719SG).
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.
Example: 2 x log 100 x (1+3) = 16
Including *1,
*2, *3
Omitting *1,
Omitting *3

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
(1) Replace an entry (1234567 1234560)
(2) Deletion (1234567 134567)
