[. . . ] If the Main Menu shown above is not on the display, press the P button on the back of the calculator to perform memory reset. Use the cursor keys (f, c, d, e) to select the CONT icon and press Use f and c to move the pointer to CONTRAST. Press e to make the figures on the display darker, and d to make them lighter. Use f and c to move the pointer to the color you want to adjust (ORANGE, BLUE, or GREEN). [. . . ] This calculator includes a number of built-in scientific functions, including trigonometric and logarithmic functions. Be sure that you specify Deg (degrees) as the angle unit before you try this example. With the replay feature, simply press or to recall the last calculation that was performed. This recalls the calculation so you can make changes or re-execute it as it is. The symbol " { " is used to separate the various parts of a fraction. The graphing capabilities of this calculator makes it possible to draw complex graphs using either rectangular coordinates (horizontal axis: x ; vertical axis: y) or polar coordinates (angle: ; distance from origin: r). Example 3: Determine the area bounded by the origin and the X = ­1 root obtained for Y = X(X + 1)(X ­ 2) X = ­1, and then press then press D to move the pointer to the location where w. Next, use e to w to input the integration range, which Move the pointer to the location where X = 0, and becomes shaded on the display. With this function you can split the display between two areas and display two graphs on the same screen. Example: To draw the following two graphs and determine the points of intersection J, and then input the two functions. Use and to move the pointer to one corner of the area you want to specify and then . Dynamic Graph lets you see how the shape of a graph is affected as the value assigned to one of the coefficients of its function changes. Example: To draw graphs as the value of coefficient A in the following function changes from 1 to 3 The Table Function makes it possible to generate a table of solutions as different values are assigned to the variables of a function. Example: To create a number table for the following function To learn all about the many powerful features of this calculator, read on and explore! ⷠAvoid dropping your calculator and subjecting it to strong impact. ⷠDo not store the calculator or leave it in areas exposed to high temperatures or humidity, or large amounts of dust. When exposed to low temperatures, the calculator may require more time to display results and may even fail to operate. Correct operation will resume once the calculator is brought back to normal temperature. ⷠThe display will go blank and keys will not operate during calculations. When you are operating the keyboard, be sure to watch the display to make sure that all your key operations are being performed correctly. ⷠReplace the main batteries once every 2 years regardless of how much the calculator is used during that period. Avoid using volatile liquids such as thinner or benzine to clean the unit. [. . . ] Stored data can also be affected by strong electrostatic charge or strong impact. Since this calculator employs unused memory as a work area when performing its internal calculations, an error may occur when there is not enough memory available to perform calculations. To avoid such problems, it is a good idea to leave 1 or 2 kbytes of memory free (unused) at all times. Be liable to anyone for special, collateral, incidental, or consequential damages in connection with or arising out of the purchase or use of these materials. [. . . ]
