The exercises are aimed at familiarizing yourself with the basic operations and settings before actually performing a calculation. Basic Operations The following exercises are aimed at getting you acquainted with the hardware of your calculator. Batteries The calculator uses 3 AAA (LR03) batteries as main power and a CR2032 lithium battery for memory backup. Before using the calculator, please install the batteries according to the following procedure. To install the main batteries a. Make sure the calculator is OFF. Slide up the battery compartment cover as illustrated. b. Insert 3 new AAA (LR03) batteries into the main compartment. Make sure each battery is inserted in the indicated direction. To install the backup battery a. Make sure the calculator is OFF. Press down the holder. Push the plate to the shown direction and lift it. Page 1-1 b. Insert a new CR2032 lithium battery. Make sure its positive (+) side is facing up. c. Replace the plate and push it to the original place. After installing the batteries, press [ON] to turn the power on. Warning: When the low battery icon is displayed, you need to replace the batteries as soon as possible. However, avoid removing the backup battery and main batteries at the same time to avoid data lost. Turning the calculator on and off The $ key is located at the lower left corner of the keyboard. Press it once to turn your calculator on. To turn the calculator off, press the red right-shift key @ (first key in the second row from the bottom of the keyboard), followed by the $ key. Notice that the $ key has a red OFF label printed in the upper right corner as a reminder of the OFF command. Adjusting the display contrast You can adjust the display contrast by holding the $ key while pressing the + or -keys. The $(hold) + key combination produces a darker display The $(hold) -key combination produces a lighter display Contents of the calculator’s display Turn your calculator on once more. At the top of the display you will have two lines of information that describe the settings of the calculator. The first line shows the characters: (Highlight) RAD XYZ HEX R= 'X' Page 1-2 For details on the meaning of these specifications see Chapter 2 in the calculator’s user’s guide. The second line shows the characters (Highlight) { HOME } indicating that the HOME directory is the current file directory in the calculator’s memory. At the bottom of the display you will find a number of labels, namely, @EDIT @VIEW @@ RCL @@ @@STO@ ! PURGE !CLEAR associated with the six soft menu keys, F1 through F6: ABCDEF The six labels displayed in the lower part of the screen will change depending on which menu is displayed. But A will always be associated with the first displayed label, B with the second displayed label, and so on. Menus The six labels associated with the keys A through F form part of a menu of functions. Since the calculator has only six soft menu keys, it only display 6 labels at any point in time.
