Resetting the HP 39gs
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, “To erase all memory and reset
defaults”.
To reset using
the keyboard
Press and hold the key and the third menu key
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 in
the back of the calculator.
2. Insert the end of a straightened metal paper clip into
the hole as far as it will go. Hold it there for 1
second, then remove it.
3. Press If necessary, press and the first and
last menu keys simultaneously. (Note: This will erase
your calculator memory.)
To erase all memory and reset defaults
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 key, the first menu key, and
the last menu key simultaneously.
2. Release all keys in the reverse order.
Note: To cancel this process, release only the top-row
keys, then press the third menu key.
views The possible contexts for an aplet:
Plot, Plot Setup, Numeric, Numeric
Setup, Symbolic, Symbolic Setup,
Sketch, Note, and special views like
split screens.
