2.2 EPROM Installation
The Protegé® 616 software consists of one EPROM
that must be mounted in the IC socket on the Central
Control Board. Follow the steps below to mount it:
1) Connect the grounding wrist strap to an
approved ground.
2) Find the anti-static bag containing the EPROM
chip for the CCB.
3) Place an anti-static bag on a level surface, and,
observing static discharge precautions, place
the KSU on the bag.
4) Being careful not to touch the chip pins,
remove the EPROM from its carrier.
5) Insert the EPROM in its socket. Align the notch
on the chip with the notch on the socket. Make
sure that all pins are properly seated.
6) Replace the KSU cover and the four screws
that hold it in place.
7) Move the RAM switch from On to Reset. Wait
10 seconds and return the switch to the On
position.
