Tube Disposal
After the results have been printed and you have reviewed the printout(s) for clarity, open the instru-
ment door by pressing the door release latch. Remove the QBC STAR tube. Discard the tube in a
biohazard container.
Power Down
If desired, after testing is completed you can turn instrument power off by placing the power switch
in the off “O” position. Note that if you leave the power on continuously, the instrument will perform
a power-on-self-test every eight hours and print electronic QC results.
Stopping the Centrifuge
If for some reason you must stop the test before it is complete, press the “Star” key to stop the instru-
ment.
Note that you cannot reuse or reanalyze a partially processed tube.
It is perfectly normal for the analyzer to make clicking noises during the testing process. This does not
indicate an abnormal condition. The system automatically stops testing if a power failure or system error
occurs, or the unit breaks down. If this occurs, a message appears on the LCD display.
Emergency Door Unlock
In the event of a power failure or the failure of certain components, you may be unable to open the door
with the door release latch. If this occurs, you can still open the door. Emergency door unlock is performed
by tripping the internal latch with a screwdriver.
To unlock the door:
1 Make sure the power switch is in the “Off” position (O) and the power cord is disconnected from
the instrument.
2 Lift the front of the instrument and rest the QBC STAR instrument on its rear panel.
3 Locate the door latch access hole in the bottom of the instrument. It is almost directly below the
door release latch. (See Figure 21.)
4 Insert a small diameter screwdriver that has a shaft at least 2 inches long.
5 Press down against the internal latch by pivoting the screwdriver handle upward. This step may
require a moderate amount of pressure.
6 When the door pops open, remove the screwdriver and place the QBC STAR instrument in its
normal upright position.
