Operational error messages
During initialization, calibration, and operation, the home screen may
sometimes displays “<Error>”. This type of error is usually catastrophic,
preventing further operation, halting the fluorescence output, and suspending
the display. In most cases, you can cycle power (shut down, wait 10 seconds,
then restart) to correct the error. However, if the error persists, contact
Waters Technical Service (see page 4-2 ).
