Resetting the NXT
If the running icon stops spinning, your NXT has frozen
and you will need to reset it. Follow these steps to reset your NXT:
Make sure that your NXT is turned on.
Push the reset button that is located on the back of
your NXT in the LEGO
®
Technic hole in the upper left
corner. Use, for example, an unfolded paperclip to
press the button.
If you press the reset button for more than 4 seconds
you will need to update the fi rmware [see below].
Updating the fi rmware in the NXT from your computer
Go to Tools > Update NXT Firmware.
Make sure that your NXT is turned on.
Note! If you have just reset your NXT (see above)
the display will not show anything. A ticking sound
will tell whether it is turned on or not.
Make sure that your NXT and computer are connected
with the USB cable.
Go to the Tools pull-down menu in the software’s
menu bar and select Update NXT Firmware.
