4. Clean only with a soft, dry cloth.
5. Do not use or store the calculator where fluids can
splash onto it.
♦Press the RESET switch only in the following cases:
• When using for the first time
• After replacing the batteries
• To clear all memory contents
• When an abnormal condition occurs and all keys are
inoperative.
If service should be required on this calculator, use only a
SHARP servicing dealer, SHARP approved service facil-
ity, or SHARP repair service where available.

(During actual use not all symbols are displayed at the
same time.)
If the value of mantissa does not fit within the range
±0.000000001 – ±9999999999, the display changes to
scientific notation. The display mode can be changed ac-
cording to the purpose of the calculation.

displayed. Press </>to see the remain-
ing (hidden) section.
2ndF : Appears when @is pressed, indicating that
the functions shown in yellow are enable.
HYP : Indicates that hhas been pressed and the
hyperbolic functions are enabled. If @Á
are pressed, the symbols “2ndF HYP” appear,
indicating that inverse hyperbolic functions are
enabled.
A:Indicates that @Kor O(R) has
been pressed, and entry (recall) of memory con-
tents and recall of statistics can be performed.
FIX/SCI/ENG: Indicates the notation used to display a
value and changes each time @fare
pressed.

INITIAL SETUP
Mode Selection
Normal mode: @m0
Used to perform arithmetic operations and function calcu-
lations.
Statistics mode: @m1
Used to perform statistical calculations.
When executing mode selection, temporary memories, sta-
tistical data and last answer memory will be cleared even
when reselecting the same mode.
Selecting the Display Notation and Decimal
Places
The calculator has four display notation systems for dis-
playing calculation results. When FIX, SCI, or ENG sym-
bol is displayed, the number of decimal places can be set
to any value between 0 and 9. Displayed values will be
reduced to the corresponding number of digits.

[Temporary memories (X and Y)]
A stored value can be recalled as a value or variable for
the use in equations.
• In case you store an infinite decimal in the memory,
recall it as a variable to obtain accurate answers.
Ex.) 1 /3 OY(0.3333...is stored to Y)

0.999999999

[Independent memory (M)]
In addition to all the features of temporary memories, a
value can be added to or subtracted from an existing
memory value.
[Last answer memory (ANS)]
The calculation result obtained by pressing =or any
other calculation ending instruction is automatically stored
in the last answer memory.
Note:
Calculation results from the functions indicated below are
automatically stored in memories X or Y. For this reason,
when using these functions, be careful with the use of
memories X and Y.

Determination of the Angular Unit
In this calculator, the following three angular units can be
specified.
Random Numbers
A pseudo-random number with three significant digits can
be generated by pressing @` =. To generate
the next random number, press =. You can perform
this function in the normal and statistics modes.
• Random numbers use memory Y. Each random number
is generated on the basis of the value stored in memory
Y (pseudo-random number series).

ERROR AND CALCULATION RANGES
1. Errors
An error will occur if an operation exceeds the calculation
ranges, or if a mathematically illegal operation is attempted.
When an error occurs, pressing <(or >) automati-
cally moves the cursor back to the place in the equation
where the error occurred. Edit the equation (see page 4)
or press Nto clear the equation.
In the statistical calculation formulas, an error will occur when:
• the absolute value of the intermediate result or calcula-
tion result is equal to or greater than 1 ×10100.
• the denominator is zero.
• an attempt is made to take the square root of a negative
number.
Syntax error (Error 1):
• An attempt was made to perform an invalid operation.
Ex. 2 @{
Calculation error (Error 2):
• The absolute value of an intermediate or final calculation
result equals or exceeds 10100.
• An attempt was made to divide by 0.
• The calculation ranges were exceeded while performing
calculations.
Depth error (Error 3):
• The available number of buffers was exceeded. (There are 8
buffers* for numeric values and 16 buffers for calculation
instructions). *4 buffers in STAT mode.
Equation too long (Error 4):
• The equation exceeded its maximum input buffer (159 char-
acters). An equation must be shorter than 159 characters.
3. Calculation Ranges
• Within the ranges specified below, this calculator is
accurate to ±1 in the least significant digit of the
mantissa. When performing continuous calculations (in-
cluding chain calculations), errors accumulate leading
to reduced accuracy.
• Calculation ranges
±10-99 ~ ±9.999999999×1099 and 0.
If the absolute value of an entry or a final or intermediate
result of a calculation is less than 10–99, the value is con-
sidered to be 0 in calculations and in the display.

BATTERY REPLACEMENT
Notes on Battery Replacement
Improper handling of batteries can cause electrolyte leak-
age or explosion. Be sure to observe the following han-
dling rules:
• Replace both batteries at the same time.
• Do not mix new and old batteries.
• Make sure the new batteries are the correct type (LR44).
• When installing, orient each battery properly as indi-
cated in the calculator.
• Batteries are factory-installed before shipment, and may
be exhausted before they reach the service life stated in
the specifications.
When to Replace the Batteries
If the display has poor contrast, the batteries require re-
placement.
Caution
• Keep batteries out of the reach of children.
• Exhausted batteries left in the calculator may leak and
damage the calculator.
• Explosion risk may be caused by incorrect handling.
• Batteries must be replaced only with others of the same
type.
• Do not throw batteries into a fire as they may explode.
Replacement Procedure
1. Turn the power off by pressing @F.
2.
Loosen both screws and remove the battery cover. (Fig. 1)
Fig. 1 Fig. 2
3. Remove the used batteries then replace with two fresh
batteries with the positive sides (+) facing up. (Fig. 2)
