puller tool. To remove the chip, align the hooks of
a PLCC IC puller tool with the slots located in
opposite ends of the U1 firmware chip.

tool gently to grasp the chip.
7. Pull the chip straight out of the socket, and set it
aside.
8. Align the slots of the new firmware chip with the
angled corners of the socket in the same
orientation as the old chip.
9. Gently, but firmly, press the chip into place in the
socket.
