The usage threshold gives a warning once the number of remaining uses for a cleaning tape falls below the threshold. You should replace cleaning tapes after a certain number of uses (generally 50 max).

1. Click Cells/Tapes in the left navigation area of the GUI.
2. Click the Cleaning Tapes tab.
3. Click Set Cleaning Thresholds .
4. Set the threshold for each type of cleaning tape. The threshold will apply to all cleaning tapes of that type. Set the threshold high enough to allow adequate time to replace the tape. The default threshold is 5 remaining uses.
