DISPLAY SYMBOLS
–Negative symbol
Indicates the displayed number is a negative number.
M Memory symbol
Appears when number is stored in memory.
2ndF Second function symbol
Appears when 2ndF is pressed, allowing access to alternate key functions.
HYP Hyperbolic function designation symbol
Appears when a hyperbolic function is designated.
DEG Degree mode symbol
Appears when degree mode is designated or shows that the angular mode of the converted result is in degrees.
RAD Radians mode symbol
Appears when radian mode is designated or shows that the a n g u l a r mode of the converted result is in radians.
GRAD Grad mode symbol
Appears when grad mode is designated or shows that the angular mode of the converted result is in grads.
( ) Parenthesis symbols
Appears when a calculation with parenthesis is performed by pressing the parenthesis key.

4
BIN Binary mode symbol
Appears when the binary mode is set or the displayed result is a binary number.
OCT Octal mode symbol
Appears when the octal mode is set or the displayed result is an octal number.
HEX Hexadecimal mode symbol
Appears when the hexadecimal mode is set or the displayed result is a hexadecimal number.
CPLX Complex number mode symbol
Appears when the complex number mode is set.
STAT Statistical mode symbol
Appears when the statistical calculations mode is set.
A calculated result is displayed as a floating point number within the range of:
0.000000001 ≤ 1 x ≤ 9999999999
Results outside this range are displayed in scientific notation.
SETTING UP DISPLAY FORMAT
Display Format
Press TAB key to change format from floating point to scientific notion
Change to scientific notion
Change to floating point
Setting Decimal Point
Press 2ndF, TAB and Number of digit
Example: Decimal Point 4
6 |
7 |
Example: Decimal Point 6
Please note:
Once the decimal point is set, it will remain after power is off, to resume decimal point 2 (default), Please set the decimal point to 2 again.
Example:
Setting back to Decimal Point 2
OPERATING THE CALCULATOR
Power off key
Press to turn off the calculator. Automatically turns off 8 minutes after last keypress to conserve battery power.
Power on and clear / statistical calculation mode key
Press to turn on the calculator or to clear the display.
Press to activate statistical program. The display is cleared and STAT appears in the display. In this mode the ), x -->m, RM and M+ keys function as the n, x, S and DATA keys respectively. Press 2ndF to activate the ∑ x, ∑ x2, Ó and CD keys.
2nd function key
Press to use alternate functions located above most keys.

Degree / Radian / Grad selector / angular unit conversion key
Use to calculate trigonometric and coordinate conversion. The DRG key changes the angular mode with each press:
DEG -> RAD -> GRAD -> DEG.
DEG MODE - Entries and results are in decimal degrees. RAD MODE - Entries and results are in radians.
GRAD MODE - Entries and results are in grads.
Functions the same as the DEG key. The displayed number is converted into a number of the specified angular mode.
Hyperbolic / Arc Hyperbolic key
Used with trigonometric functions for hyperbolic calculations.
Used with trigonometric functions for arc hyperbolic calculations.
Trigonometric / Inverse Trigonometric function keys
Press for the desired trigonometric function. Press 2ndF first for inverse trigonometric functions.
Display Format Exchange / Tabulation key
Press to change display format from floating point to scientific notation and back again.
Press 2ndF, TAB, then a digit to specify the number of decimal tab places in the displayed result.
