5. Operation
It has been noted already that the PAUSE/STOP key should be
pressed only ONCE when additional slides are to be loaded.
Because if the PAUSE/STOP key is pressed TWICE, processing
is stopped. If this happens, the message opposite appears in the
display.
• This means that the staining run has been aborted, and the
instrument must be reset by pressing ENTER.
Important!
All slide carriers must be removed from the instru-
ment, because all the information in the software has
been reset.
• As soon as the user presses the ENTER key in this situation,
the transfer mechanism returns to the home position. This is
then the same situation as when the instrument is first
switched on.
• The corresponding message appears in the display.
• As soon as the transfer mechanism reaches the start posi-
tion, the stainer returns to idle mode; then, the same status
message is displayed as the one shown when the instrument
is initialized after it is switched on.
5.5.4 Ending a staining run prematurely
The role of the PAUSE/STOP key in loading additional slides was described in the previous
chapter.
However, this key has a second function, that of terminating a staining run that has already
been started.
