5. Gently pry the EPROM to be replaced out of its socket with a
small screwdriver or other instrument. Pry at one end then the
other until the EPROM is free from its socket. Use care so that
surrounding circuitry is not damaged.
6. The EPROM has a small notch on one end of the chip. The
socket has a matching notch. Align the notches (see Figure)
while making sure that each of the EPROM’s legs are aligned
with the mating holes in the socket.
7. Press slowly to seat the EPROM in its socket. Visually examine
the installation to insure that all of the EPROM legs are inserted
in their holes.
8. Reassemble the bottom plate and/or ML-BATT module onto the
MLCPU-1 module and reinstall the four side retaining screws.
9. Power up the OMP-MODL. The LCD should display some
verbage (which indicates that the EPROM is correctly installed).
Perform a 3-button initialization at this time with the
following procedure:
A. Depress and hold the NEXT button down on the front
panel.
B. Momentarily, depress the STOP and RESET buttons
simultaneously, then release them.
C. After a second or so, release the NEXT button.
This sequence will result in a complete initialization of the unit.
After a short sequence of display messages on the LCD, a
SYSTEM INITIALIZED message should display momentarily
indicating that the logger was properly initialized. If this
message does not display, repeat the procedure.
10. After initialization, reprogram the logger with a new Net
Program and the unit is ready to deploy
