the EPROM from the DSU circuit card. Note the
location and orientation of the notch at one end of

When installing an EPROM on
the DSU, ensure that the notch
on the EPROM is pointing
downward on the circuit card.
Installing the EPROM in the
opposite orientation will
damage the EPROM and cause
overheating which may result
in possible injury to you.
