This softkey displays the latched status of the following fault
messages.
EEROM FAIL Indicates that the EEROM (electrically erasable
read only memory) has failed to store data properly.

and I/O system performed at power-on has failed.
The front panel INSTR CHECK LED lights. Initiate
a full self-test to gather more information if this fault

defaulted either deliberately or due to an EEROM
failure.
