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,) 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 calculators 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. 2nd functions 1st functions 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 2ndF 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 2ndF indicator. E-2
(Note) : [ A ], [ B ], [ C ], [ D ], [ E ], [ F ] are 1st functions in HEX mode.

Display formats

The calculator can display numbers in four formats : floating point, fixed point, scientific, 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 ] [ ] 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 Step 2 : key in 3.256 [ = ] E-3

DEG DEG DEG

0.00 3.26
On the contrary, if fewer than the selected number of decimal places is keyed, it will be padded with trailing zero. (Ex.) : Fix the display at 4 decimal places, then key in 4.23 Step 1 : press [ 2ndF ] [ TAB ] 4 Step 2 : key in 4.23 [ = ] Scientific display format In Scientific display format, the number 891500 can be shown in scientific format as 8.915 x 10 05, where 8.915 is called the mantissa and 5 is as the exponent of 10. (Ex.) : 7132 x 125 is displayed in scientific display format. Step 1 : key in 7132 [ x ] 125 [ = ]

0.0000 4.2300

891500.
DEG Step 2 : press [ FE ] 8.(in floating point format) Besides, entry can be made in scientific notation by using the [ E X P ] key after entering the mantissa. (Ex.) : Key the number 4.82296 x 10 5
Step : key in 4.82296 [ EXP ] 5 (in floating point format) Engineering display format

4.82296

The format is similar to the scientific format, expect the mantissa can have up to three digits left of the decimal, instead of only one, and the exponent is always a multiple of three. It is useful for engineers to convert units based on multiples of 10 3. (Ex.) : Convert 15V into 15000mV (V : Volt) Step 1 : key in 15 Step 2 : press [ ENG ] twice (Ex.) : Convert 15V into 0. 015KV (V : Volt) Step 1 : key in 15 Step 2 : press [ 2ndF ] [ ] twice

Order of operations

Each calculation is performed in the following order of precedence : 1) Operation in parenthesis 2) Functions required pressing the function key before entering, for example, [ DATA ] in STAT mode and [ EXP ] key. 3) Functions required inputing values before pressing the function key, for example, cos, sin, tan, cos1, sin1, tan1, log, ln, X 2, 1/x, , , , ,,, , ,, , and 6 units conversion. , X!, %, RND, ENG, 4) Fractions E-4

Correction

If you have made a mistake when entering a number (but you have not yet pressed an arithmetic operator key), just press [ CE ] to clear the last entry then input it again, or delete individual digits by using the backspace key [ ] (Ex.) : Correct 12385 as 789 Step : press [ CE ] 789 (Ex.) : Correct 12385 as 123 Step : press [ ] twice

Step 4 : Press [ = ] and [ 2ndF ] [ EDIT ] to exit ED mode, where those data are changed as data 1 = 3.00, data 2~5 = 5.00, data 6~8 = 9.00. (Ex.5) : Based on Ex.1, delete data 1 = 2. Method 1 : Press 2 [ 2ndF ] [ DEL ] to delete 2. Method 2 : Step 1 : Press [ 2ndF ] [ EDIT ] Step 2 : Find out 2 by [ DATA ] or [ = ] Step 3 : Press [ 2ndF ] [ DEL ]

0.00 2.00 5.00

Step 4 : Press [ 2ndF ] [ EDIT ] to exit ED mode, where those data are changed as data 1~4 = 5.00, data 5~7 = 9.00.

Delete error

(Ex.6) : If you enter and delete a value that isnt included in the stored data by mistake, dEL Error appears, but the previous data are still retained, for example, delete 7 based on Ex.1. Step 1 : Press 7 [ 2ndF ] [ DEL ] Step 2 : Press any key to clear it

DEG STAT

dEL Error
Step 3 : Enter ED mode, then view data by [ DATA ] or [ = ], where those data are still data 1 = 2.00, data 2~5 = 5. 00, data 6~8 = 9.00. (Ex.7) : Based on Ex.1, enter 5 x 5 and delete it. Step 1 : Press 5 [ x ] 5 [ 2ndF ] [ DEL ] Step 2 : Press any key to clear it

Step 3 : Enter ED mode, then view data by [ DATA ] or [ = ], where those data are changed as data 1 = 2.00, data 2~4 = 9.00.
Weighted data entry method
Instead of entering directly each data, when often several item of data have the same value, you can enter the value and the number of occurrences up to 255. The data based on Ex.1 can be rewritten and entered as follow : Value 9 Number of occurrences 3 Alternative method [ DATA ] 2 [ DATA ] 5 [ x ] 4 [ DATA ] 9 [ x ] 3
, where data 1 = 2, data 2~5 = 5, data 6~8 = 9. Under ED mode, when you continue choosing a value from data 2~5 and correcting it as 33, the permutation among those data will be changed as data 1 = 2, data 2~4 = 5, data 5 = 33, data 6~8 = 9, where the new value 33 is inserted after data 4 = 5. (Note) : A FULL is indicated when any of the following conditions occur and further data entry becomes impossible. Just pressing any key can clear the indicator. The previous data entries are still retained unless exiting STAT mode. 1) If the times of data entry by [ DATA ] is more than 80 2) The number of occurrences is more than 255 3) n 20400 (n = 20400 appears when the times of data entry by [ DATA ] are up to 80 and the number of occurrences for each value are all 255, i.e. 20400 = 80 x 255.)
