"Switching Off" (Page 85) and section 9.3 "Switching Off" (Page 85).
2. Open the housing of the Sunny Island 3324/4248 (see section 6.1 "Removing

4. Briefly touch the bare metal of the Sunny Island 3324/4248 housing (for
electrostatic discharge).
5. Use the PLCC tool to remove the old EPROM, by carefully inserting the hooked
end of the tool into the right-hand cutout in the socket, thus allowing you to lever
the EPROM out of the socket at this corner. Carefully slide the tool under the
EPROM until you can remove the component from the socket.
