Errors
An error will occur if an operation exceeds the calculation
ranges, or if a mathematically illegal operation is attempted.
In the case of an error, the display will show “E”.
An error can be cleared by pressing ª.

Calculation Ranges
• Within the ranges specified, this calculator is accurate to
±1 of the least significant digit of the mantissa. However, a
calculation error increases in continuous calculations due
to accumulation of each calculation error. (This is the
same for yx, x¿ , ex, ln, etc., where continuous calculations
are performed internally.)
Additionally, a calculation error will accumulate and
become larger in the vicinity of inflection points and
singular points of functions.
• 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 considered to be 0 in calculations and in the display.

3. Remove the used batteries then replace with two fresh
batteries with the positive sides (+) facing up. (Fig. 2)
4. Replace the battery cover and screws.
5. Press ª.
• Make sure that the display appears as shown below. If the
display does not appear as shown, reinstall the batteries
and check the display once again.

priority:
1 Functions such as sin, x2, and %
2 yx, x¿y
3 ×, ÷
4 +, –
5 =, M+ and other calculation ending instruction
• Calculations which are given the same priority level are
executed in sequence.
• If parentheses are used, parenthesized calculations have
precedence over any other calculations.
• Parentheses can be continuously used up to 15 times unless pending calculations exceed 4.

• Refer to the calculation examples of each function.
• For most calculations using functions, enter numerical
values before pressing the function key.

Random Numbers
A pseudo-random number with three significant digits can be
generated by pressing @ `. Random number generation is not possible when binary/octal/hexadecimal system mode is set.

Angular Unit Conversions
Each time @ g are pressed, the angular unit changes
in sequence.

Memory Calculations
This calculator has one independent memory (M). It is available in the normal mode and binary, octal, hexadecimal
system mode.
• The independent memory is indicated by the three keys:
O, R, ;.
Before starting a calculation, clear the memory by pressing ª and O.
• A value can be added to or subtracted from an existing
memory value. When subtracting a number from the
memory, press ± and ;.
• The contents of the memory are retained even when the
calculator is turned off. A value stored in memory will thus
remain until it is changed or until the batteries run out.

Chain Calculations
This calculator allows the previous calculation result to be
used in the following calculation.
The previous calculation result will not be recalled after entering multiple instructions.

Time, Decimal and Sexagesimal Calculations
This calculator performs decimal-to-sexagesimal conversion
and sexagesimal-to-decimal conversion. In addition, the four
basic arithmetic operations and memory calculations can be
carried out using the sexagesimal system.
Notation for sexagesimal is as follows:

BATTERY REPLACEMENT
Notes on Battery Replacement
Improper handling of batteries can cause electrolyte leakage
or explosion. Be sure to observe the following handling rules:
• Replace both batteries at the same time.
• Do not mix new and old batteries.
• Make sure the new batteries are the correct type.
• When installing, orient each battery properly as indicated 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 replacement.

Caution
• Fluid from a leaking battery accidentally entering an eye could
result in serious injury. Should this occur, wash with clean
water and immediately consult a doctor.
• Should fluid from a leaking battery come in contact with your
skin or clothes, immediately wash with clean water.
• If the product is not to be used for some time, to avoid damage
to the unit from leaking batteries, remove them and store in a
safe place.
• Do not leave exhausted batteries inside the product.
• Do not fit partially used batteries, and be sure not to mix
batteries of different types.
• 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.
• Do not throw batteries into a fire as they may explode.

Note: When the calculation or conversion result is converted, a residual may occur.

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

Errors
An error will occur if an operation exceeds the calculation
ranges, or if a mathematically illegal operation is attempted.
In the case of an error, the display will show “E”.
An error can be cleared by pressing ª.

Calculation Ranges
• Within the ranges specified, this calculator is accurate to
±1 of the least significant digit of the mantissa. However, a
calculation error increases in continuous calculations due
to accumulation of each calculation error. (This is the
same for yx, x¿ , ex, ln, etc., where continuous calculations
are performed internally.)
Additionally, a calculation error will accumulate and
become larger in the vicinity of inflection points and
singular points of functions.
• 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 considered to be 0 in calculations and in the display.

3. Remove the used batteries then replace with two fresh
batteries with the positive sides (+) facing up. (Fig. 2)
4. Replace the battery cover and screws.
5. Press ª.
• Make sure that the display appears as shown below. If the
display does not appear as shown, reinstall the batteries
and check the display once again.

Automatic Power Off Function
This calculator will turn itself off to save battery power if no
key is pressed for approximately 8 minutes.
