Selecting the Display Notation and Decimal Places
The calculator has four display notation systems for displaying calculation
results. When FIX, SCI, or ENG symbol is displayed, the number of decimal
places can be set to any value between 0 and 9.
Displayed values will be reduced to the corresponding number of digits.

Determination of the Angular Unit
In this calculator, the following
three angular units can be specified.

Refer to the calculation examples of each function.
Random Numbers
A pseudo-random number with three significant digits can be generated
by pressing
@

=
. To generate the next random number, press
=. You can perform this function in the normal and statistics modes.
•
Random numbers use memory Y. Each random number is generated on the
basis of the value stored in memory Y (pseudo-random number series).
•
The clo sing parenthesis ) just before = or ; may be omitted.

least significant digit of the mantissa. When performing continuous calculations
(including chain calculations), errors accumulate leading to reduced accuracy.

Notes on Battery Replacement
Improper handling of batteries can cause electrolyte leakage or explosion.
Be sure to observe the following handling rules:
When to Replace the Battery
If the display has poor contrast or nothing appears on the display even
when is pressed in dim lighting, it is time to replace the battery.
Caution
• 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.
•
An exhausted battery left in the calculator may leak and damage the calculator.
•
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 a leaking battery, remove it and store in a safe place.
• Keep batteries out of the reach of children.
• Explosion risk may be caused by incorrect handling.
• Do not throw batteries into a fire as they may explode.
• Do not leave an exhausted battery inside the product.

Editing the Equation
• Press or
to move the cursor. You can also
return
to the
equation after getting an answer by pressing
( ).
•
If you need to delete a number, move the cursor to the number
you
wish to delete then press d . If the cursor is located at the right
end of an equation, the d key will function as a back space key.
•
If you need to insert a number, move the cursor to the place immediately
after where you wish to insert the number then enter the number.
[Temporary memories (
X, Y, r ,
θ)]
Press O and a variable key to store a value in memory.
Press R and a variable key to recall the value from that memory.
To place a variable in an equation, press
@K
and a variable key.
Use of R or
@K
will recall the value stored in memory using up
to 14 digits.
This calculator has four temporary memories (X, Y, r ,
θ
), one
independent memory (M) and one last answer memory (ANS).
Independent memory and temporary memories are only available in the
normal mode.
