Note that the MACS II unit does not perform certain
operations due to mechanical interference. For example, if
the cell is raised, then it is not possible to pull out the
drawer. The software flags such an operation as illegal.
If the cell is under pressure, none of the operations can be
performed until the pressure is released. In such a case all
elements of the screen are unavailable (gray).
