v G et ting Acquainted — Read This First ! I About this User’s Guide S Model-specific Function and Screen Differences This User’s Guide covers multiple different calculator models. Note that some of the functions described here may not be available on all of the models covered by this User’s Guide.
vi the mode the calculator is in, and current operation assignments are indicated by function menus that appear at the bottom of the display. • This User’s Guide shows the current operation assigned to a function key in parentheses following the key cap for that key.
1-1 Chapter 1 Basic O pe ration 1. Keys I Key Table Not all of the functions described above are available on all models covered by this manual. Depending on calculator model, some of the above keys may not be included on your calculator.
1-2 I Key Markings Many of the calculator’s keys are used to perform more than one function. The functions marked on the keyboard are color coded to help you find the one you need quickly and easily. Function Key Operation log J 10 x J B ?J The following describes the color coding used for key markings.
1-3 3. Press U to display the initial screen of the mode whose icon you selected. Here we will enter the STAT mode. • You can also enter a mode without highlighting an icon in the Main Menu by inputting the number or letter marked in the lower right corner of the icon.
1-4 Icon Mode Name Description TVM* 1 (Financial) Use this mode to perform financial calculations and to draw cash flow and other types of graphs. E-CON2* 1 Use this mode to control the optionally available EA-200 Data Analyzer. For more information about the E-CON2 mode, download the E-CON2 manual (English version only) from: http://edu.
1-5 1.2 E –03 indicates that the result is equivalent to 1.2 s 10 –3 . This means that you should move the decimal point in 1.2 three places to the left, because the exponent is negative. This results in the value 0.0012. You can specify one of two different ranges for automatic changeover to normal display.
1-6 I Editing Calculations Use the B and C keys to move the cursor to the position you want to change, and then perform one of the operations described below. After you edit the calculation, you can execute it by pressing U . Or you can use C to move to the end of the calculation and input more.
1-7 I Using Replay Memory The last calculation performed is always stored into replay memory. You can recall the contents of the replay memory by pressing B or C . If you press C , the calculation appears with the cursor at the beginning. Pressing B causes the calculation to appear with the cursor at the end.
1-8 U Press ) . Cursor is positioned automatically at the location of the cause of the error. Make necessary changes. B @ Execute again.
