•
Do not carry the calculator around in your back pocket, as it
may break when you sit down. The display is made of glass
and is particularly fragile.
Keep the calculator away from extreme heat such as on a car
dashboard or near a heater, and avoid exposing it to exces-
sively humid or dusty environments.
Since this product is not waterproof, do not use it or store it
where fluids, for example water, can splash onto it. Raindrops,
water spray, juice, coffee, steam, perspiration, etc. will also
cause malfunction.
Clean with a soft, dry cloth. Do not use solvents or a wet cloth.
Do not drop it or apply excessive force.

SHARP strongly recommends that separate permanent
written records be kept of all important data. Data may be
lost or altered in virtually any electronic memory product
under certain circumstances. Therefore, SHARP assumes
no responsibility for data lost or otherwise rendered unusable
whether as a result of improper use, repairs, defects, battery
replacement, use after the specified battery life has expired,
or any other cause.
All variables are cleared.

use an object with a breakable or sharp tip. Note that pressing
the RESET switch erases all data stored in memory.

[Insert mode and Overwrite mode in the Equation display]
If service should be required on this calculator, use only a SHARP
servicing dealer, SHARP approved service facility, or SHARP
repair service where available.

Pressing @‘ switches between the two editing modes:
insert mode (default); and overwrite mode. A triangular cursor
indicates that an entry will be inserted at the cursor, while the
rectangular cursor indicates to overwrite preexisting data as you
make entries.
Differential/Integral Functions
Differential and integral calculations are only available in the nor-
mal mode. For calculation conditions such as the x value in differ-
ential calculation or the initial point in integral calculation, only
numerical values can be entered and equations such as 22 cannot
be specified. It is possible to reuse the same equation over and
over again and to recalculate by only changing the conditions with-
out re-entering the equation.

2x + 2y =14, once you enter the equation, all you have to do is to
specify the value for the variable in the formula.
Usable variables: A-F, M, X and Y
Unusable functions: Random function

Correction prior to pressing k immediately after a data entry:
Enter the value of each item (‘ROW’, ‘COLUMN’, and then each
element, e.g. ‘MAT1,1’) and press k after each. After enter-
ing all items, press ª, then press °2 and specify
matA-D to save the data.
Delete incorrect data with ª, then enter the correct data.

Performing Calculations
Q Press m0.
Each item is displayed with ‘Xn=’, ‘Yn=’, or ‘Nn=’ (n is the sequen-
tial number of the data set).
W Input a formula with at least one variable.
E Press @≤.

Before performing calculations, press ª to close the matrix
edit buffer.
Display the data item to modify, input the correct value, then
press k. Using &, you can correct the values of the data
set all at once.
R Variable input screen will appear. Input the value of the flashing
variable, then press ® to confirm. The calculation result will
be displayed after entering the value for all used variables.
When results of calculations are in the matrix format, the matrix
edit buffer with those results will be displayed. (At this time, you
cannot return to the equation.) To save the result in matA-D,
press ª, then press °2 and specify matA-D.
Since there is only one matrix edit buffer, the previous data will
be overwritten by the new calculation.
In addition to the 4 arithmetic functions (excluding divisions be-
tween matrices), x3, x2, and x–1, the following commands are
available:
•

To delete a data set, display an item of the data set to delete,
then press @J. The data set will be deleted.
To add a new data set, press ª and input the values, then
press k.
•
•
•
Only numerical values are allowed as variables. Input of
formulas is not permitted.
•
•
Upon completing the calculation, press @≤ to per-
form calculations using the same formula.
Variables and numerical values stored in the memories will
be displayed in the variable input screen. To change a
numerical value, input the new value and press ®.
Performing simulation calculation will cause memory loca-
tions to be overwritten with new values.
