IC chip by grasping it firmly with your fingers and pulling it out; then
continue to step 8.

tool. To remove the U41 chip, align the hooks of a
PLCC IC puller tool with the slots located in opposite
ends of the U41 firmware chip.

gently to grasp the chip.
7. Pull the chip straight out of the socket, and set it aside.
8. For U17 and U38, align the notch of the new firmware
chip with the notch of the socket in the same
orientation as the old chip.
For U41, align the angled
corner of the firmware
chip with the angled
corner of the socket.
9. Gently, but firmly, press
the chip into place in the
socket.
