Resetting the HP 40gs 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. R-3
