Before Using the Calculator
     Check the current Calculation Mode
Be sure to check the status indicators that indicate the 
current calculation mode (SD, REG... etc), display formats 
setting and angle unit setting (Deg, Rad, Gra) before 
starting a calculation.
 
     Return Calculation Mode to the initial setup 
You can return the calculation mode to the initial default by 
pressing                    (Mode)     Calculation Mode  : COMP
Angle Unit  : Deg
Exponential Display Format  : Norm 1 
Fraction Display Format  : a b/c
Decimal Point Character  : Dot
and this action will not clear the variable memories.
    Initialize the Calculator 
When you are not sure the current calculator setting, you 
are recommended to initialize the calculator (calculation 
mode COMP, angle unit Degree, and clear replay and 
variable memories), and LCD contrast by performing the 
following key operations:                     (All)
Display Formats Setting
F-715SG can display a result up to 10 digits. Results 
exceed the digit limit will be automatically displayed by 
exponential notation format. You can enter a value in 
floating-decimal, fixed-decimal, or scientific notation format 
and display format setting only affects the calculation 
results. (Example #1)

Input Capacity 
F-715SG allows you to input a single calculation up to 79 
steps.    
Starting from the 73rd step, the cursor changes from [ _ ] to 
[     ] that notifying the memory is running low. In case you 
need to input a single calculation with more than 79 steps, 
you should separate your calculation into two or more 
segments.
INPUTTING EXPRESSIONS AND VALUES
Input Editing
New input begins on the left of the upper (entry) line. As the 
entries are more than 12 digits, the line will scroll to the 
right consecutively.
Press      ,      to scroll the cursor within the upper (entry) 
line and you can perform input editing as needed. 
(Example #2) •  After deleting an input by        or clearing the input 
  by        ,      icon will be shown on the display.
•  Press               to resume up to 79         deleted input or to undo the cleared segment and back to the previous 
display.
•  If pressed        ...        to delete character(s) then clear  the display, the calculator will prioritize the undo from 
resuming the latest         cleared characters, and 
followed with the deleted characters continuously.
•  After inserting a new data or executing a calculation  command, or pressing        , the calculator cannot 
perform the Undo function.

•  After inserting a new data or executing a calculation  command, or pressing        , the calculator cannot 
perform the Undo function.
Replay, Copy and Multi-statements Replay  •  Replay memory capacity is 256 bytes that can store calculation expressions and results.  
•  After the calculation is executed, the calculation  expression and its result will be stored in the replay 
memory automatically. 
•  Pressing     (or    ) can replay the performed calculation  expressions and results. 
•  Replay memory is cleared when you.  i)  Initialize calculator setting by                
  (or                       ).
ii)  Change from one calculation mode to another.
iii) Press         key.
iv) Turn off the calculator by              .
Copy  •  Press              after replaying the previous calculation expressions (statements).
Multi-statements •  You can put two or more calculation expressions together by using a colon       .
•  The first executed statement will have [Disp] indicator;  and the [Disp] icon will disappeared after the last 
statement is being executed. (Example #3)

INPUT RANGE AND ERROR MESSAGE
Calculation Stacks
 This calculator uses memory areas, called stacks, to 
temporarily store numeric value (numbers) and 
commands (+ – x ...) according to their precedence 
during calculations.
  The numeric stack has 10 levels and the command stack  has 24 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.
Calculation Accuracy, Input Ranges
Order of Operations
  In the same precedence level, calculations are performed from left to right.
  Operation enclosed within paredtheses is performed  first. When a calculation contains an argument that is a 
negative number, the negative number must be 
enclosed within parentheses. 
–22 = –4
(–2)
2 = 4

Error Messages and Error Locator
The calculator is locked up while an error message is 
shown on the display to indicate the cause of the error. 
  Press        will clear the error, remove all replay 
memory and return to initial display of the latest mode.
  Press        will clear the error message and return to  the display of the latest mode.
  Press      or      to display the calculation with the  cursor positioned under the error and you can correct 
it accordingly.
Error MessageCause Action
Math 
ERROR
• Calculation result is  outside the allowable 
calculation range
• An attempt to perform  a calculation using a 
value that exceeds the 
allowable input range.
• An attempt to perform  an illogical operation 
(division by zero, etc.) Check your input 
values and make 
sure they are all 
within the allowable 
ranges. Pay special 
attention to values in 
any memory areas 
you are using.
Stack 
ERRORThe capacity of the 
numeric stack or 
operator stack is 
exceeded.
Simplify the 
calculation. The 
numeric stack has 10 
levels and the 
operator stack has 
24 levels.
Divide your 
calculation into two 
or more separate 
parts.
Syntax 
ERRORAn attempt to perform 
an illegal mathematical 
operation.
Press     or     to
