AY, |, A{ and Z for memory calculations.
AY replaces current memory contents.
• “M” appears when there is a value in memory.
• To clear memory, press
0AY or tAY.
• Example 1: (536)(238)(562)(994) 210.75

• Use COMP mode for fraction calculations.
• Total number of digits (including division marks) cannot
exceed 10.
• Example 1: 1

Handling Precautions
• Be sure to press the 5 key before using the calculator.
• Your calculator is made up of precision components.
Never try to take it apart.
• Avoid dropping your calculator and otherwise subjecting it
to strong impact.
• Do not store the calculator or leave it in areas exposed to
high temperature or humidity, or large amounts of dust.
When exposed to low temperatures, the calculator may
require more time to display results and may even fail to
operate. Correct operation will resume once the calculator
is brought back to normal temperature.
• The display will go blank and keys will not operate during
calculations. When you are operating the keyboard, be
sure to watch the display to make sure that all your key
operations are being performed correctly.
• With certain calculations, it may take some time before the
result is displayed. The display is blank while a calculation
is in progress.
• Avoid using volatile liquids such as thinner or benzine to
clean the unit. Wipe it with a soft cloth, or with a cloth
that has been dipped in a solution of water and a neutral
detergent and wring out.
• In no event will the manufacturer and its suppliers be liable
to you or any other person for any damages, expenses,
lost profits, lost savings, or any other damages arising
out of malfunction, repairs, or insufficient light. The user
should prepare physical records of data to protect against
such data loss.
• Never dispose of the liquid crystal panel, or other
components by burning them.
• Before assuming malfunction of the unit, be sure to
carefully reread this manual and ensure that the problem
is not due to operational error.
• The contents of this manual are subject to change without
notice.
• No part of this manual may be reproduced in any form
without the express written consent of the manufacturer.
• Be sure to keep all user documentation handy for future
reference.

•
F0 does not clear SCI or FIX specifications.
• Always press
t before entering DEG, RAD, and GRA
modes.
• Remember to always set the operating mode and angular
unit (DEG, RAD, GRA) before starting your calculation.

k Exponential Display Formats
This calculator can display up to 10 digits. Larger values are
automatically displayed using exponential notation. In the
case of decimal value, you can select between two formats
that determine at what point exponential notation is used.
• NORM 1
With NORM 1, exponential notation is automatically used
for integer values with more than 10 digits and decimal
values with more than two decimal places.
• NORM 2
With NORM 2, exponential notation is automatically used
for integer values with more than 10 digits and decimal
values with more than nine decimal places.
To switch between NORM 1 and NORM 2
Press
F 9. There is no indication on the display of which
format is currently in effect, but you can determine the
setting by performing the following calculation.
1 \ 200 =
5.
–03
NORM 1 format
0.005
NORM 2 format
• All of the examples in this manual show calculation results
using the NORM 1 format.
k When you have a problem......
If calculation results are not what you expect or if an error
occurs, perform the following steps.
1.
F 0 (COMP mode)
2.
F 4 (DEG mode)
3.
F 9 (NORM mode)
4. Check the formula you are working with to confirm it is
correct.
5. Enter the correct modes to perform the calculation and
try again.
k Making Corrections During Calculations
• If you make a mistake when inputting a value (but did
not yet press an operator key), use
Q to backspace and
delete input digits one-by-one. Or you can press
k to
clear the input entirely and start again.
• In a series of calculations, press
k while an intermediate
result is displayed to clear only the last calculation
performed.
• To change the operator key (
+, ,, -, \, w, As,
etc.) you just pressed, simply press the correct operator
key. In this case, the operator of the last key you press is
used, but the operation retains the order of precedence of
the operation for the first key you pressed.
k Overflow or Error Check
The following conditions make further calculation impossible.
a. When a result (whether intermediate or final) or a total
accumulated in memory is greater than ±9.999999999
10
99
. (“–E–” indicator appears on the display.)
b. When function calculations are performed using a value
that exceeds the input range. (“–E–” indicator appears
on the display.)
c. When an illogical operation (such as an attempt to
calculate
o and σn while n 0) is performed during
statistical calculations. (“–E–” indicator appears on the
display.)
d. When an illegal mathematical operation (such as division
by zero) is performed. (“–E–” indicator appears on
display.)
e. The total number of nested parentheses levels exceeds
six, or when more than 18 pairs of parentheses are used.
(“– 1–” indicator appears on the display.)
• To clear any of the above conditions, press
t and
perform the calculation from the beginning.
• In the case of condition e, you could also press
k. This
clears the intermediate result just prior to the overflow, so
you can continue with the calculation from that point.
• No error occurs when the result is within the range of
(110
99
) to (110
99
). Instead, the display shows all
zeros.
k Power Supply
This calculator is powered by a solar cell that converts
available light into electrical power.
Solar Cell Precautions
• The solar cell requires at least 50 lux of light to provide
power.
• If available light is too low, the display may become dim,
calculation functions may become impossible, or the
contents of the independent memory may be lost. If this
happens, move to an area with more light.
k Order of Operations and Levels
Operations are performed in the following order of
precedence.
1. Functions
2.
x
y
, x
1
/
y
, R →P, P →R, nPr, nCr
3. ,
4. ,
• Operations with the same precedence are performed
from left to right, with operations enclosed in parentheses
performed first. If parentheses are nested, the operations
enclosed in the innermost set of parentheses are
performed first.
• Registers L
1
through L
6
store operations. There are six
registers, so calculations up to six levels can be stored.
• Each level can contain up to three open parentheses, so
parentheses can be nested up to 18 times.

• For a single calculation, calculation error is 1 at the 10th
digit. (In the case of exponential display, calculation error
is 1 at the last significant digit.) Errors are cumulative
in the case of consecutive calculations, which can also
cause them to become large. (This is also true of internal
consecutive calculations that are performed in the case of
x

In the vicinity of a function’s singular point and point of
inflection, errors are cumulative and may become large.
