5. Operation
If the PAUSE/STOP and RUN keys are pressed in this order, the
instrument receives the information that more slide carriers
have been inserted at the start position.
The stainer continues operating until these slide carriers are
transferred from station 14 to the exit tank.
If no other slides have been added in the meantime, it emits an
audible signal to alert the operator that the staining run has
been completed. A corresponding message appears in the
display.
5.5.3 Temporarily pausing a staining run
This procedure applies for inserting slide carriers af-
ter processing has begun, and must be followed un-
der all circumstances.
Attempting to add slide carriers without pressing the
PAUSE and RUN keys will result in the carriers not
being transported to all of the stations, since the
stainer will not know that additional slide carriers
have been added!
Occasionally, it may be necessary to stop the system when it is processing slides. This too can
be accomplished with PAUSE/STOP key.
Staining can be interrupted,
• to allow access to the instrument if anomalies requiring such arise during staining.
• so that reagents can be checked, and changed if necessary.
Important!
The lift bar will complete the current cycle, and will
move the slide carriers to the next station. Do not
attempt to open the instrument until "LOAD SLIDES...
PRESS RUN" appears in the display.
