+==== Venting the column ===
+To vent the column (eg. to change samples or inspect/replace filament):
+  - Press the VENT button on the vacuum control panel
+  - Wait a surprisingly long time (until hissing is done)
+  - Open chamber / gun, do your work, close it.
+  - Press the EVAC button on the vacuum control panel.
+==== Using the EDX system ====
+The detector is currently not mounted, but you can try using the system for image acquisition.
+  - Power on the Dell PC, wait for a boot to desktop
+  - Start the 'NSS ohne drift' script from the desktop
+  - Start the 'NSS' software from the desktop
+  - Select an existing or create a new project
+  - Ignore the warning about the detector being at high temperature (it's not, it's just disconnected)
+  - Select 'microanalysis imaging' (IIRC?) from the mode on the left
+  - Press play to do a live acquisition, press the gradient button to do a high quality acquisition
+If everything goes well, the DSM will go into 'External Scan' mode and the acquisition will succeed. If the DSM goes into 'slow image scan' which can't be canceled, congratulations, you've hit The Bug Which We're Debugging.
