Introduction to the TI83/84
Clearing the memory of the TI83/84 graphing calculator:
Some of you may have used calculators, and these calculators may have items stored in memory by the
previous owner.
In addition, after you have been using your calculator for a few weeks, you may find
that you have quite a bit of clutter in the memory.
To clear all memory of the calculator, press
2
nd
,
MEM
(the second function of the + key).
Choose
Reset
.
The calculator will want to know whether
you wish to reset
All RAM
, or just the defaults.
Choose
All RAM
.
The calculator also wants to
protect you from inadvertently deleting items that you want to keep, so the calculator will ask you,
“
RESET RAM
”?
Choose
Reset
.
The calculator will then tell you, “
RAM cleared
.”
