Resetting the hp 39g+

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.

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.

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.
