Omit the multiplication sign and final close parenthesis.
Press to switch a calculation result between fraction and
decimal format.
Press to switch a calculation result between
improper fraction and mixed fraction format.
Result will be displayed in decimal format automatically
whenever the total digit of a fractional value (integer +
numerator + denominator + separator marks) exceeds 10.
As a fraction calculation is mixed with decimal value, the
result will be displayed by decimal format.
*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 , ,
, .
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 Maths mode, you can only use the insert mode.
Whenever the display format changes from Line mode to
Maths mode, it will automatically switch to the insert mode.
Arithmetic Calculations
To calculate with negative values (exclude the negative
exponent) enclose then with parentheses.
This calculator supports 99 levels of parenthetical
expression.
Press to enter COMP mode.
During the busy calculation, the calculator shows only
the indicators (without any calculation result). You can
press key to interrupt the calculating operation.
Power ON, OFF
First time operation:
1. Pull out the battery insulation sheet, then the battery will
be loaded.
2. Press to reset the calculator.
Power ON: When is pressed.
Power OFF: are pressed.
Auto Power off Function:
When the calculator is not used for about 7 minutes, it
will automatically power off.
Display Contrast Adjustment
Press (5: CONT ), enter the
Display Contrast Adjustment screen.
Press to make the display contrast darken.
Press to make the display contrast lighten.
Press or to confirm and clear the screen.
To initialize the LCD contrast, press

Remark
(1) Some input expressions cause the height of a
calculation expression to be greater than one display
screen. Maximum input capacity: 2 display screen
(31 dots x 2).
(2) Calculator memory limits how many functions or
perentheses 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
press or to view the full expression.

Calculation results may be displayed using when all of
the following cases:-
1. When intermediate and final calculation results are
displayed in the following form:
2. When the number of terms in the intermediate and final
calculation result is one or two.
In the same precedence level, calculations are
performed from left to right.
Operation enclosed within parentheses is performed
first. When a calculation contains an argument that is a
negative number, the negative number must be enclosed
within parentheses.

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 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 while an error message is shown on
the display to indicate the cause of the error.
Press to clear the error message, then return to the
initial display of latest mode.
Press or to display input expression with the cursor
positioned next to the error.
Press to clear the error message, clear the replay

Memory Calculations
Memory Variables
There are 17 memory variables (0 – 9, A – D, M, X and
Y), which store data, results, or dedicated values.
Store values into memory by pressing + Memory
variable.
Recall memory values by pressing + Memory
variable.
Memory content can be cleared by pressing
+ Memory variable.
Example: 23 + 7 A (30 store into A), calculate 2 sinA
and clear memory A.
Independent Memory
Independent memory uses the same memory area
as variable M. It is convenient for calculating cumulative
total by just pressing (add to memory) or
(subtract from memory)
Memory contents are retained even when the calculator
is powered off.
Clear independent memory (M) by pressing
Clear all memory values by pressing 2(MCL)
Answer Memory
The input values or the most recent calculation result will
be automatically stored into Answer memory whenever
you press , , , , . Answer
memory can hold up to 18 digits.
Recall and use the latest stored Answer memory by
pressing .
Answer memory is not updated as an error operation
had been performed.
Answer memory contents can be maintained even if
