Appendix A Resetting the Calculator Warning! The procedure described here clears all memory contents. Never perform this operation unless you want to totally clear the memory of the calculator. If you need the data currently stored in memory, be sure to write it down somewhere before performing the RESET operation. u To reset the calculator 1. Press m to display the main menu. E 2. Highlight the MEM icon and press w, or press c. 3. Use c to move the highlighting down to “Reset” and then press w.
Resetting the Calculator Appendix A Resetting the calculator initializes it to the following settings.
Appendix B Power Supply This unit is powered by four AAA-size (LR03 (AM4) or R03 (UM-4)) batteries. In addition, it uses a single CR2032 lithium battery as a back up power supply for the memory. If the following message appears on the display, immediately stop using the calculator and replace batteries. If you try to continue using the calculator, it will automatically switch power off, in order to protect memory contents. You will not be able to switch power back on until you replace batteries.
Power Supply Appendix B Keep batteries out of the reach of small children. If swallowed, consult with a physician immediately. u To replace the main power supply batteries * Never remove the main power supply and the memory back up batteries from the unit at the same time. * Never replace the main power supply battery compartment cover or switch the calculator on while the main power supply batteries are removed from the calculator or not loaded correctly.
Appendix B Power Supply u To replace the memory back up battery * Before replacing the memory back up 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.
Appendix C Error Message Table Meaning Message Syn ERROR 1 Calculation formula contains an error. 2 Formula in a program contains an error. Ma ERROR Go ERROR 1 Use d or e to display the point where the error was generated and correct it. 2 Use d or e to display the point where the error was generated and then correct the program. 1 Calculation result exceeds calculation range. 2 Calculation is outside the input range of a function. 3 Illogical operation (division by zero, etc.
Appendix C Error Message Table Message Stk ERROR Countermeasure Meaning • Execution of calculations that exceed the capacity of the stack for numeric values or stack for commands. • • Mem ERROR • • • • • • • • • Not enough memory to input a function into function memory. Not enough memory to create a matrix using the specified dimension. Not enough memory to hold matrix calculation result. Not enough memory to store data in list function. Not enough memory to input coefficient for equation.
