Selecting the display notation and decimal places
Five display notation systems are used to display calculation
results: Two settings of Floating point (NORM1 and NORM2),
Fixed decimal point (FIX), Scientific notation (SCI), and
Engineering notation (ENG).
• When J 1 0 (FIX) or J 1 2 (ENG) is
pressed, “TAB(0–9)?” will be displayed and the number of
decimal places (TAB) can be set to any value between 0 and 9.
• When J 1 1 (SCI) is pressed, “SIG(0–9)?” will be
displayed and the number of significant digits can be set to any
value between 0 and 9. Entering 0 will set a 10-digit display.
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.
Press j x M to clear the independent memory (M).
Last answer memory (ANS)
The calculation result obtained by pressing = or any other
calculation ending instruction is automatically stored in the
last answer memory.
Setting the floating point number system in scientific notation
Two settings are used to display a floating-point number: NORM1
(the default) and NORM2. A number is automatically displayed in
scientific notation outside a preset range:
Notes:
• Calculation results from the functions indicated below are
automatically stored in the X or Y memories replacing any

Selecting the editor
Two editors are available in NORMAL mode:
• The WriteView editor (W-VIEW): J 2 0 (default)
• The Line editor (LINE): J 2 1
Definable memories (D1–D4)
You can store functions or operations in definable memories
(D1–D4).
Adjusting the display contrast
Press J 3, then + or & to adjust the contrast.
Press j to exit.
• To store a function or operation, press x, followed by
a definable memory key (I, J, K, or L),
followed by the operation you want to store. Menu-related
operations, such as J, cannot be stored. Press j to
return to the previous display.
• To call a stored function or operation, press the
corresponding memory key. Calling a stored function will do
nothing if the function that is called would be unusable in the
current context.
Insert and overwrite entry methods
When using the Line editor, you can change the entry method
from “INSERT” (the default) to “OVERWRITE”.
After you switch to the overwrite method (by pressing J 4
1), the triangular cursor will change to a rectangular one, and
the number or function underneath it will be overwritten as you
make entries.
• Any functions or operations that are stored in a definable
memory will be replaced when you save a new one into that
memory.
SCIENTIFIC CALCULATIONS
• Press b 0 to select NORMAL mode.
• In each example, press j to clear the display first. Unless
otherwise specified, calculation examples are performed in the
WriteView editor with the default display settings (@ P

• When displaying and correcting a data set in STAT mode,
you cannot store functions or operations in definable
memories.

Constant Calculations
Arithmetic operations and memory calculations can be
performed using fractions. In NORMAL mode, conversion
between a decimal number and a fraction can be performed
by pressing U.
• In constant calculations, the addend becomes a constant.
Subtraction and division are performed in the same manner.
For multiplication, the multiplicand becomes a constant.
• In constant calculations, constants will be displayed as K.
Notes:
• Improper/proper fractions will be converted to and displayed
as decimal numbers if the number of digits used in their
expression is greater than nine. In the case of mixed
fractions, the maximum number of displayable digits
(including integers) is eight.
• To convert a sexagesimal value to a fraction, first convert it
by pressing @ :.
Binary, Pental, Octal, Decimal, and Hexadecimal
Operations (N-base)
Conversions can be performed between N-base numbers
in NORMAL mode. The four basic arithmetic operations,
calculations with parentheses, and memory calculations can
also be performed, along with the logical operations AND,
OR, NOT, NEG, XOR, and XNOR on binary, pental, octal, and
hexadecimal numbers.

Question
Decimal calculation results are internally obtained in scientific
notation, with up to 14 digits in the mantissa. However, since
calculation results are displayed in the form designated by the
display notation and the number of decimal places indicated,
the internal calculation result may differ from that shown in the
display. By using the modify function (@ n), the internal
value is converted to match that of the display, so that the
displayed value can be used without change in subsequent
operations.

Alert Messages
6.Replace the cover and screws.
7.Press the RESET switch (on the back) with the tip of a
ball-point pen or similar object.
8.Adjust the display contrast. See “Adjusting the Display
Contrast”.
• Make sure that the display appears as shown below. If the
display does not appear as shown, remove the battery,
reinstall it, and check the display once again.
Cannot delete!
• The selected item cannot be deleted by pressing N or
@ y in the WriteView editor.
Ex. * 5 r A l N
In this example, delete the exponent before attempting to
delete the parentheses.
Cannot call!
• The function or operation stored in definable memory (D1 to
D4) cannot be called.
Ex. An attempt was made to recall a statistical variable from
within NORMAL mode.
Buffer full!
• The equation (including any calculation ending instructions)
exceeded its maximum input buffer (159 characters in the
WriteView editor or 161 characters in the Line editor). An
equation may not exceed its maximum input buffer.

Calculation Ranges
• Within the ranges specified, this calculator is accurate to
1 of the 10th digit of the mantissa. However, a calculation
error increases in continuous calculations due to
accumulation of each calculation error. (This is the same

Additionally, a calculation error will accumulate and
become larger in the vicinity of inflection points and

Improper handling of batteries can cause electrolyte leakage or
explosion. Be sure to observe the following handling rules:
• Make sure the new battery is the correct type.
• When installing, orient the battery properly as indicated in the
calculator.
• The battery is factory-installed before shipment, and may
be exhausted before it reaches the service life stated in the
specifications.
