TROUBLESHOOTING
ANALYTICAL STATION MESSAGES
Corrective Action
1. Reset the Analytical Station.
2. Perform F44 FLOWCELL UNCLOG 1 function.
3. If message recurs, repeat F44 FLOWCELL UNCLOG
1 function.
4. If message recurs, perform F45 FLOWCELL
UNCLOG 2 function, up to three times.
CAUTION Risk of instrument damage. Using F46
can damage the flow cell because it places greater
stress on the flow cell than F44 or F45. Only use F46
if F44 and F45 fail to clear the clog, and never do F46
more than once unless specifically instructed to do
so by your Beckman Coulter Representative.
5. If message recurs, perform F46 FLOWCELL
UNCLOG 3 function once.
6. Allow Analytical Station to sit idle for 30 minutes.
Then perform F44 FLOWCELL UNCLOG 1 function
before analyzing samples.
7. If message persists, call your Beckman Coulter
Representative.
Enter correct function for Analytical Station's mode of
operation.
