General guide
Power supply
On or Off :
To turn the calculator on, press [ON/C]; to turn the calculator off, press
[2ndF] [OFF].
Auto power-off function :
This calculator automatically turns off it when not operated for
approximately 9 minutes. Power can be restored by pressing the [ON/C]
key again. Memory contents and the previous mode setting (STAT, DEG,
CPLX, Base-n,β¦) are retained even when power is turned off or auto
power-off.
Battery replacement :
The calculator uses two alkaline button batteries GP76A(LR44) for
power. If the display becomes dim and difficult to read, the batteries should
be replaced as soon as possible.
To replace batteries:
1) Remove the screws that hold the back cover.
2) Remove the back cover.
3) Replace the old batteries and install new ones with polarity in correct
directions.
4) Secure the screws in place, then press [ON/C] to turn the power on.
The keyboard
Many of the calculatorβs keys are used to perform more than one function.
The functions marked on the keyboard are printed differently to help you find
the one you need quickly and easily.
1st functions
Those are the functions that are normally executed when you press the key.
2nd functions
The second function is printed above or to the right of the key. To execute
2nd functions key, please press [ 2ndF ] then the corresponding key. When
you press [ 2ndF ], the β 2ndF β indicator shown in the display is to tell you
that you will be selecting the second function of the next key you press. If you
press [ 2ndF ] by mistake, simply press [ 2ndF ] again to remove the β 2ndF
β indicator.

(Note) : [ A ], [ B ], [ C ], [ D ], [ E ], [ F ] are 1st functions in HEX mode.
Display symbols
Indicators shown on the display is to indicate you the current status
of the calculator.
DEG or RAD or GRAD : angular unit
M : Independent memory CPLX : Complex number mode
E : Overflow / Error STAT : Statistical mode
β : minus 2ndF : [2ndF] key pressed
( ) : Parenthesis calculation CP : Precision capability
BIN : Binary mode CPK : Process capability
OCT : Octal mode : Deviation
HEX : Hexadecimal mode USL : Setting upper limit
ED : Edit mode LSL : Setting lower limit
HYP : Hyperbolic mode
Display formats
The calculator can display numbers in four formats : floating point, fixed
point, scientiο¬c, and engineering.
Floating point display format
The floating point format displays numbers in decimal form, using up
to 10 digits. Any trailing zeros are truncated.
If the result of a calculation is too large to be represented in 10 digits,
the display automatically switches to scientific format. If the result of later
calculations is small enough to be displayed in 10 digits, the calculator
returns to floating point format.
(Ex.) : Set the display in floating display format.
Step : Press [ 2ndF ] [ TAB ] [ β’ ] DEG 0.
Fixed point display format
The fixed point, scientific, and engineering formats use a fixed number
of decimal places to display numbers. If more than the selected number of
decimal places is keyed, it will be rounded to the correct number of decimal
places.
(Ex.) : Fix the display at 2 decimal places, then key in 3.256
Step 1 : press [ 2ndF ] [ TAB ] 2 DEG 0.00
Step 2 : key in 3.256 [ = ] DEG 3.26
