The keylock on the front panel allows you to disable the
keyboard and RESET button and lock the top cover of the
main unit for security. The keyboard may be locked while the
system is in operation. This disables the keyboard so no
one can interfere with the current operation.
To lock the system, insert the key with the notch pointing
left and turn it clockwise. You must press the key in slightly
when you turn it. To unlock the system, insert the key with
the notch pointing up and turn the key counterclockwise.
You can remove the key in either position.
