Input of statistical data is limited to six decimal places. 17. Error Messages The calculator will display an error message whenever an error occurs for any reason during a calculation. • Press d or e to return to the calculation screen. The cursor will be positioned at the location where the error occurred, ready for input. Make the necessary corrections to the calculation and execute it again. (Not included on the fx-82SX PLUS) • Press A to return to the calculation screen. Note that this also clears the calculation that contained the error. Math ERROR Cause: • The intermediate or final result of the calculation you are performing exceeds the allowable calculation range. • Your input exceeds the allowable input range. • The calculation you are performing contains an illegal mathematical operation (such as division by zero). Action: • Check the input values and reduce the number of digits. • When using independent memory or a variable as the argument of a function, make sure that the memory or variable value is within the allowable range for the function. Stack ERROR Cause: The calculation you are performing has caused the capacity of the numeric stack or the command stack to be exceeded. Action: • Simplify the calculation expression. • Try splitting the calculation into two or more parts. Syntax ERROR Cause: There is a problem with the format of the calculation you are performing. Action: Make necessary corrections. Arg ERROR Cause: Improper use of an argument. Action: Make necessary corrections. 18. Before Assuming Malfunction of the Calculator... Perform the following steps whenever an error occurs during a calculation or when calculation results are not what you expected. Note that you should make separate copies of important data before performing these steps. 1. Check the calculation expression to make sure that it does not contain any errors. 2. Make sure that you are using the correct mode for the type of calculation you are trying to perform. 3. If the above steps do not correct your problem, press the O key. 4. Initialize all modes and settings. See “Initializing Calculator Settings”. 19. Replacing the Battery Important: Removing the battery will cause all of the calculator’s memory contents to be deleted. 1. Press 1A(OFF) to turn off the calculator. • To ensure that you do not accidentally turn on power while replacing the battery, slide the hard case onto the front of the calculator (fx-350MS). 2. Remove the cover as shown in the illustration and replace the battery, taking care that its plus (+) and minus (–) ends are facing correctly.

Initializing the Calculator”. • Do not skip the above step! 20.
