6.2.3.2 Unblocking Stations
To unblock a blocked station:
1 From the Test display, select Block/Unblock.
2 The Block/Unblock display appears.
3 Make sure the correct instrument is open (highlighted in green).
4 Blocked stations are shown with a station icon.
5 Select the blocked station in the display that you want to unblock.
6 Repeat for additional stations to be unblocked.
7 Select Exit to return to the Maintenance – Test display.
6.2.4 Replacing Vial Barcode Labels
Extra vial sequence barcode labels are included in the instrument start-up kit. These labels can be
used to replace damaged or unreadable labels on culture vials. The barcode labels contain sequence
numbers that uniquely identify each vial.
Note that if you replace a vial barcode label, when you enter that vial into the instrument (either through
Vial Entry or through Identify Anonymous), it asks you to select a media type. This enables the system
to apply media-specific positivity criteria to the vial.
Required materials:
• Spare barcode label
To apply a new barcode label:
1 Insure that the area where the defective label is located is clean and dry. If the old label is
wrinkled or creased, peel off as much as possible to make a smooth surface on which to apply
the new label.
2 Peel off the new barcode label. Verify that the new label is printed clearly and that no smears,
smudges, or other markings obstruct the lines of the barcode.
3 Align the new label with the old label, and press the new label into place, being careful not to
create any bubbles or ridges in the bar code area.
4 Be sure to select the correct medium type in the Culture – Vial display. This enables the
instrument to apply media-specific positivity criteria to test readings.
6.2.5 Cleaning and Decontamination
A situation requiring biological decontamination of one or more stations can occur if a vial should leak
or break while in the instrument. The priority in this situation is to first limit the extent of the
contamination and then to decontaminate the station(s) and other accessible instrument areas
receiving the spill. If the spill extends into regions of the instrument not accessible for topical
decontamination, or if it involves a broken vial, contact BD Technical Service and Support (USA) for
further instructions (800.638.8663).
The solution recommended to clean the affected surfaces should be at least a 10% household bleach
solution. All surfaces must be thoroughly washed with the freshly prepared bleach solution, so that the
surfaces are glistening wet. If you are not sure of the extent of the contamination, thoroughly wash the
exposed portions of the rack and cabinet with the freshly prepared bleach solution.
