Mantissa Exponent

(During actual use not all symbols are displayed at the same time.) If the value of mantissa does not fit within the range ±0.000000001 – ±9999999999, the display changes to scien- tific notation. The display mode can be changed according to the purpose of the calculation.

2ndF	: Appears when @is pressed, indicating that the
	functions shown in orange are enabled.
HYP	: Indicates that hhas been pressed and the hy-
	perbolic functions are enabled. If @Hare
	pressed, the symbols “2ndF HYP” appear, indicat-
	ing that inverse hyperbolic functions are enabled.

DEG/RAD/GRAD: Indicates angular units and changes each time Gis pressed. The default setting is DEG.

BEFORE USING THE CALCULATOR

Key Notation Used in this Manual

In this manual, key operations are described as follows:

To specify A (HEX): A

To specify π	: @V
To specify Exp	: E

Functions that are printed in orange above the key require

@to be pressed first before the key. Numbers are not shown as keys, but as ordinary numbers.

Power On and Off

Press ªto turn the calculator on, and Fto turn it off.

Clearing Numbers

•Press ª to clear the entries except for a numerical value in the independent memory and statistical data.

•Press æ to clear the number entered prior to use of function key.

•In case of one digit correction of the entered number, press ø(right shift key).
