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 is powered by two alkaline batteries (G13 or LR44). When the display dims, replace the batteries. Be careful not to be

injured when you replace the battery.

1. Unscrew the screws on the back of the calculator.

2. Insert a flat bladed screwdriver into the slot between the upper and lower case then carefully twist it to separate the case.

3. Remove both batteries and dispose of them properly. Never allow children to play with batteries.

4. Wipe off the new batteries with a dry cloth to maintain good contact.

5. Insert the two new batteries with their flat sides (plus terminals) up.

6. Align the upper and lower cases then snap them to close together.

7. Tighten the screws.

The keyboard

Many of the calculator’s 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.

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 ] [ ● ]

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

Step 2: key in 3.256 [ = ]

DEG

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 [ = ]

Step 2: press [ F↔E ]

(in floating point format)

DEG 05

8.915

Besides, entry can be made in scientific notation by using the [EXP] key after entering the mantissa.

(Ex.) : Key the number 4.82296 x 10

Step :key in 4.82296 [ EXP ] 5

(in floating point format)

Engineering display format

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

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, cos−1, sin−1, tan−1, log, ln, x2, 1/x, √, π, 3√, x!, %, RND, ENG, , , and 6 units

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 [ 00Æ0 ].

(Ex.) : Correct 12385 as 789

Step: Press [ CE ] 789

(Ex.) : Correct 12385 as 123

Step: Press [ 00Æ0 ] twice

In a series of calculations, you can correct errors in immediate results by pressing [ON/C] to clear the calculation completely (expect clearing memory, see page 9).

If you press the wrong arithmetic operation key, just press [ CE ] key before entering anything else.

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 Number of occurrences Alternative method 2 1 [ DATA ] 2 5 4 [ DATA ] 5 [ x ] 4 9 3 [ 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.)
