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 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. 2nd function

sin 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.SR-260N_English_090324.rtf SIZE: 135x75mm / SCALE 2:1 / 2009/3/24

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 ─ : minus 2ndF : [2ndF] key pressed ( ) : Parenthesis calculation CP : Precision capability BIN : Binary mode CPK : Process capability OCT : Octal mode σ : 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, 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. DEG 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 DEG Step 1: Press [ 2ndF ] [ TAB ] 2

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 DEG Step 1: Press [ 2ndF ] [ TAB ] 4 0.0000SR-260N_English_090324.rtf SIZE: 135x75mm / SCALE 2:1 / 2009/3/24

, 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. DEG Step 1: key in 7132 [ x ] 125 [ = ]

(in floating point format) 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

(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

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.

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 [ 00

0 ]. (Ex.) : Correct 12385 as 789 DEG Step: Press [ CE ] 789

(Ex.) : Correct 12385 as 123 DEG Step: Press [ 00

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. Accuracy and Capacity Accuracy : ±1 in 10th digit. Capacity : In general, every reasonable calculation is displayed up to 10 digit mantissa, or 10-digit mantissa plus 2-digit exponent up to 10
