Insufficient MEM Error
Cause:  The configuration of TABLE Mode parameters caused more than 
30 X-values to be generated for a table.
Action:  Narrow the table calculation range by changing the Start, End, and 
Step values, and try again. 
Argument ERROR
Cause:  A non-integer argument was input for the random number function 
(RanInt#).
Action:  Input only integers for the argument.
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. If one step does not 
correct the problem, move on to the next step.
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  key. This will 
cause the calculator to perform a routine that checks whether calculation 
functions are operating correctly. If the calculator discovers any abnormality, 
it automatically initializes the calculation mode and clears memory contents. 
For details about initialized settings, see “Configuring the Calculator 
Setup”.
4. Initialize all modes and settings by performing the following operation: 
(CLR)(Setup)(Yes).
Replacing the Battery
A low battery is indicated by a dim display, even if contrast is adjusted, or by 
failure of figures to appear on the display immediately after you turn on the 
calculator. If this happens, replace the battery with a new one. 
Important: Removing the battery will cause all of the calculator’s memory 
contents to be deleted. 
1. Press (OFF) to turn off the calculator.
2. Remove the cover as shown in the illustration 
and replace the battery, taking care that its plus 
(+) and minus (–) ends are facing correctly. 
3. Replace the cover.
4. Initialize the calculator: 
(CLR)(All)(Yes)
