I. Menu Keys - Keys that offer choices

J. MEM

The MEM (memory) menu allows you to manage your memory by deleting variables, programs, etc. You can check the amount of memory you have and you can reset the memory to the default settings. However, since there is no undelete ability, be certain that you are deleting something you no longer need.

Example: Delete the lists in your calculator.

Press and go to the fourth option.
When you press ENTER, the home screen will appear and you should press ENTER again.

To delete a variable, program, etc. you access the memory menu and press the second option.

Example: Delete the variable Y1.

Access the memory menu and press 2.
Go to the Y-Vars option. This indicates that there are four functions typed in the graph menu.
You can delete whichever variable is selected by hitting the (delete) button.

Remember: There is no undelete, so be careful with this menu.
