5. Removal of the U1 IC chip requires a PLCC IC
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.
6. Insert the hooks into the slots, and squeeze the
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.
10. Replace the top cover on the VSC, and fasten it
with the screws that were removed in step 3.
11. Rack/furniture mount the scan converter, connect
the input/output cables, and reconnect the AC
power cord.
