A dead battery can leak, causing damage to and malfunction of the
calculator. Never leave a dead battery in the calculator. Do not try using
the calculator while the battery is completely dead.
• The battery that comes with the calculator discharges slightly during
shipment and storage. Because of this, it may require replacement
sooner than the normal expected battery life.
• Do not use an oxyride battery* or any other type of nickel-based
primary battery with this product. Incompatibility between such
batteries and product specifications can result in shorter battery life
and product malfunction.
• Avoid use and storage of the calculator in areas subjected to
temperature extremes, and large amounts of humidity and dust.
• Do not subject the calculator to excessive impact, pressure, or
bending.

Note: • If the calculation becomes longer than the screen width during
input, the screen will scroll automatically to the right and the ] indicator will
appear on the display. When this happens, you can scroll back to the left by
using d and e to move the cursor. • When Linear Display is selected,

e while the cursor is at the end of the input calculation will cause it to jump
to the beginning, while pressing d while the cursor is at the beginning will
cause it to jump to the end. • You can input up to 99 bytes for a calculation.
Each numeral, symbol, or function normally uses one byte. Some functions
require three to 13 bytes. • The cursor will change shape to k when there are
10 bytes or less of allowed input remaining. If this happens, end calculation
input and then press =.
Calculation Priority Sequence
The priority sequence of input calculations is evaluated in accordance with the

Important: • Certain types of expressions can cause the height of a
calculation formula to be greater than one display line. The maximum
allowable height of a calculation formula is two display screens (31 dots × 2).
Further input will become impossible if the height of the calculation you are
inputting exceeds the allowable limit. • Nesting of functions and parentheses
is allowed. Further input will become impossible if you nest too many functions
and/or parentheses. If this happens, divide the calculation into multiple parts
and calculate each part separately.
Note: When you press = and obtain a calculation result using Natural
Display, part of the expression you input may be cut off. If you need to view
the entire input expression again, press A and then use d and e to
scroll the input expression.

You can select either insert or overwrite as the input mode, but only while
Linear Display is selected. In the overwrite mode, text you input replaces the
text at the current cursor location. You can toggle between the insert and
overwrite modes by performing the operations: 1Y(INS). The cursor
appears as “I” in the insert mode and as “ ” in the overwrite mode.
Note: Natural Display always uses the insert mode, so changing display
format from Linear Display to Natural Display will automatically switch to
the insert mode.
Correcting and Clearing an Expression
To delete a single character or function: Move the cursor so it is directly to
the right of the character or function you want to delete, and then press Y.
In the overwrite mode, move the cursor so it is directly under the character
or function you want to delete, and then press Y.

To insert a character or function into a calculation: Use d and e to

function and then input it. Be sure always to use the insert mode if Linear
Display is selected.
To clear all of the calculation you are inputting: Press A.
Recurring Decimal Calculations

results also can be displayed using recurring decimal form whenever
applicable.

Recurring Decimal

display it as a recurring decimal value.
• The total number of digits used in the mixed fraction (including integer,
numerator, denominator, and separator symbol) must be no more than
10.

• The data size of value to be displayed as the recurring decimal must be no
larger than 99 bytes. Each value and the decimal point require one byte,
and each digit of the period requires one byte. The following, for example,
would require of total of 8 bytes (4 bytes for the values, 1 byte for the decimal
point, 3 bytes for the period): 0.123

Answer Memory (Ans)/Previous Answer Memory
(PreAns)
The last calculation result obtained is stored in Ans (answer) memory. The
calculation result obtained prior to the last one is stored in PreAns (previous
answer) memory. Displaying the result of a new calculation will move current
Ans memory contents to PreAns memory and store the new calculation
results in Ans memory. PreAns memory can be used only in the COMP
Mode. PreAns memory contents are cleared whenever the calculator enters

changing the initial value so they are closer to the solution. • SOLVE may not

Inputting Data
Use the Stat Editor to input data. Perform the following key operation to
display the Stat Editor: 11(STAT/DIST)2(Data).
The Stat Editor provides 40 rows for data input when there is an X column
only or when there are X and Y columns, 20 rows when there are X and FREQ
columns, or 26 rows when there are X, Y, and FREQ columns.
Note: Use the FREQ (frequency) column to input the quantity (frequency) of
identical data items. Display of the FREQ column can be turned on (displayed)
or off (not displayed) using the Stat Format setting on the setup menu.

Calculating Estimated Values
Based on the regression formula obtained by paired-variable statistical
calculation, the estimated value of y can be calculated for a given x-value.
The corresponding x-value (two values, x1 and x2, in the case of quadratic
regression) also can be calculated for a value of y in the regression
formula.
