If the calculator “locks up" and seems to be stuck, you must
reset it. This is much like resetting a PC. It cancels certain
operations, restores certain conditions, and clears temporary
memory locations. However, it does
not
clear stored data
(variables, aplet databases, programs)
unless
you use the
procedure below, “To erase all memory and reset defaults".
Press and hold the |
o n
| key and the top-row left-middle key
(top row, third from left) simultaneously, then release them.
If the calculator does not respond to the above key sequence,
then
1. Turn the calculator over and locate the small hole below
the bump (upper right). Insert the end of a straightened
metal paper clip into the hole until it reaches the bottom.
Hold it there for 1 second, then remove it.
2. Press
|ON|.
If necessary, press |
on
\+top-row,left-middle

If the calculator does not respond to the above resetting
procedures, you might need to restart it by erasing all of
memory.
You will lose everything you have stored.
All factory-
default settings are restored.
1. Press and hold the [
o n
| key, the
leftmost top-row
key, and

key simultaneously.

this process, release
