3. GENERAL GUIDE 3-1. Modes You can control the operations of the unit by entering the correct mode. To select the mode you need, select the appropriate icon from the Main Menu. The Main Menu appears whenever you press the MENU key. The icon that is highlighted is the one that is currently selected. Use the cursor keys to move the highlighting around the display to select the mode that you want. To enter the highlighted mode, press the EXE key.
TABLE Mode Use this mode to store a function or recursion formula, to generate a solution table of values produced when the values of variables in a function or recursion formula change, and to draw graphs. EQUA Mode Use this mode to solve linear equations with two through six unknowns, quadratic equations, and cubic equations. PRGM Mode Use this mode to store programs in the program area, to execute programs, and to store and execute programs as file data.

Precautions: Incorrectly using batteries can cause them to burst or leak, possibly damaging the interior of the unit. Note the following precautions: • Be sure that the positive + and negative - poles of each battery are facing in the proper directions. • Never mix batteries of different types. • Never mix old batteries and new ones. • Never leave dead batteries in the battery compartment. • Remove the batteries if you do not plan to use the unit for long periods.
4-2. To Replace the Memory Back Up Battery * Before replacing the memory backup battery, switch on the unit and check to see if the "Low battery!" message appears on the display. If it does, replace the main power supply batteries before replacing the back up power supply battery. * Never remove the main power supply and the memory back up batteries from the unit at the same time. * Be sure to switch the unit off before replacing batteries.

This should make the RESET confirmation screen appear on the display. Perform the procedure described above to complete the RESET operation.
Message Meaning Countermeasure Ne ERROR • Nesting of subroutines by Prog n exceeds 10 levels. • Ensure that Prog n is not used to return from subroutines to main routine. If used, delete any unnecessary Prog n. • Trace the subroutine jump destinations and ensure that no jumps are made back to the original program area. Ensure that returns are made correctly. Stk ERROR • Execution of calculations that exceed the capacity of the stack for numeric values or stack for calculations.
Meaning Countermeasure TRANSMIT ERROR! Problem with cable connection or parameter setting during data communications. • Check cable connection. • Check to see that the parameters of the sending unit and receiving unit are identical. RECEIVE ERROR! Problem with cable connection or parameter setting during data communications. • Check cable connection. • Check to see that the parameters of the sending unit and receiving unit are identical.
