General Operations

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 The calculator automatically turns off if it has not been used for approximately 9 minutes. Power can be restored by pressing the [ON/C] key again. Memory contents and the current mode setting (STAT, DEG, CPLX, Base-n,etc) are retained when you turn off the power and when the calculator automatically turns off. Battery replacement The calculator is powered by two alkaline button batteries (GP76A or LR44). If the display becomes dim and difficult to read, the batteries should be replaced as soon as possible. To replace the batteries: 1. 2. 3. Slide the battery cover off and remove the old batteries. Insert new batteries, with positive polarity facing outward. Replace the battery cover and press [ON/C] to turn on the power.

Before undertaking a trigonometric or inverse trigonometric calculation, make sure that the appropriate angular unit is set. 3 sin 85 = ? cos ( rad) = ? 4 tan 150 grad = ? 1 sin 0.5 = ? deg cos

Parentheses Calculations

Operations inside parentheses are always executed first. You can specify up to 15 levels of parentheses in a single calculation. When you enter the first parenthesis, the ( ) indicator appears on the display and remains until each opening parenthesis has a corresponding closing parenthesis.

In a series of calculations, you can correct errors in intermediate results by pressing [ON/C]. This clears the calculation without clearing memory. If you press the wrong arithmetic operation key, just press [ CE ] and then the correct arithmetic key.

The keyboard

Most of the keys can perform two functions. 2nd function 1st function 1st functions These are functions that are executed when you press a key without first pressing [ 2ndF ]. The function performed is indicated by the label on the key. 2nd functions These are functions that are executed when you press a key after first pressing [ 2ndF ]. The function performed is indicated by the label above the key. When you press [ 2ndF ], the 2ndF indicator appears in the display to indicate 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. 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 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 by 10 digits, the display automatically switches to scientific format. If the result of a later calculation is small enough to be displayed in less than 10 digits, the calculator returns to floating point format. To set the display to floating point display format: 1.

Converting Angular Units

You can specify an angular unit of degrees (DEG), radians (RAD), or grads (GRAD). You can also convert a value expressed in one angular unit to its corresponding value in another angular unit. The relation between the angular units is: 180 = radians = 200 grads

Corrections
If you have made a mistake when entering a number and you have not yet pressed an arithmetic operator key, just press [ CE ] to clear the last entry. You can then input the desired number again. Alternatively,you can delete digits one at a time by pressing the backspace key: [ 000 ].

If the calculator becomes locked and pressing keys has no effect, press [ M+ ] and [ ENG ] at the same time. This unlocks the calculator and returns all settings to their default values.
