CAUTION
Risk of crushing! Keep clear of the pipettor head's working and motion range, unless
operation has stopped. Otherwise, there is high risk of physical injury.
Notably, make sure that all protective covers and shielding panels are mounted and
closed, as long as the "Remove head" prompt has not appeared.
TIP
Mechanical motion of various system assemblies creates a crushing hazard for the
hands of operating personnel!
For this reason, the pipetting head top cover is monitored electronically. All electrically
powered drives will stop immediately on opening of the cover.
TIP
If you had been working in a submenu at the moment of switching power supply off, the
same menu will be restored when power becomes available again. This will also apply if
a head change procedure was not completed.
