40 -* **Never change a running system:** Do not change parameters while the Detector is running/taking data, The detector will crash.
41 -* Furthermore the module will crash if recieving to much light (e.g. illuminating with flash light during data dating.
42 -* **Checking/switching server:** The server is reachable from the GOTTHARD GUI (lower left corner find the status of the server PC "hasfl2det01") click it to open server/watchdog control. The server is otherwise found under FLASH.SYSTEM → HASFL2DET01.WATCH. Open control of SVR.GOTTHARD (for start/stop/reboot)

48 -** hard reset: power down the GOTTHARD, wait some seconds, Repower the module, wait for reconnection to server/GUI
49 -* **In case of a crashes** (no data taking, no reaction on input: Reboot the detector) or if GUI input returns error: Check connection (Power/Data), check GOTTHARD server

51 -* **Background**: Check "Take" stores the actual detector image~: Uncheck this again. Than this stored image is online subtracted from all images in the GUI when checking "subtract". The DAQ only stores raw data (NOT the background subtracted images)
