Removable flash memory operation requires a license key, a compact flash
drive, and a flash memory card. The flash drive communicates directly to the
A18 CPU through a ribbon cable.

2. Power the instrument on.
3. Check to see if Option 008 or 009 is installed in the instrument, press
Utility > Instrument Info > Diagnostic.
4. Verify the green LED to the right of the A41 Compact Flash Door, on the
instrument rear panel, turns on and off during the instrument boot-up.
5. If the green LED light does not turn on and off or Option 008/009 is not
listed as an installed option,
a. Replace the flash memory card.
b. Repeat steps 2 thru 4.
6. If the green LED light still does not turn on and off or Option 008/009 is
still not listed as an installed option,
a. Replace the A40 Compact Flash Drive.
b. Repeat steps 2 thru 4.
7. If the green LED light still does not turn on and off or Option 008/009 is
still not listed as an installed option,
a. Replace the A18 CPU
b. Run the required performance test for the A18 CPU, see Chapter 4,
“Post–Repair Procedures.”
c. Repeat steps 2 thru 4.
A flash memory card must be installed for the firmware to report Option 008/009
