Resetting the Calculator

If you are using a school calculator only in class, you may need to reset the calculator
before each use in order to erase any settings from the previous user.  Ask your teacher
if you should simply run the "Defaults" or completely reset "ALL Ram".

If you own your own calculator (and have been playing games), you should run the
"Defaults" before math class.  Games often change the calculator settings (such as turning
 off the axes).  Remember that a "complete" reset (ALL Ram) will clear memory and
delete programs and/or applications.

What are the options??

  • Start by choosing 2nd MEM
  • Select #7 Reset
  • Choose Defaults if you simply want to return the calculator to the factory settings, such as Radian mode, Normal setting, Full screen, etc.  Default will not erase programs or applications.


  • Choose All Ram if you want to reset the factory settings AND erase any programs.
  • Arrow to the right to ARCHIVE to erase applications and clear archived memory. 


  • Arrow to the right to ALL to clear everything from the calculator.


Certain examinations may require that calculators' memories be completely cleared (including
programs and APPS) prior to the test.  If you do not want to lose your programs,
be sure to back up your calculator (to another calculator or a computer) before the test.
