5. '''Dome closes unexpectedly and no other subsystem is affected''' (mirror covers stay open, telescope keeps tracking, etc.). Check the SiTech dome GUI for a "watchdog timeout" in the small font list of statuses. If this is listed, power cycle the dome muscle box, then close the autoguider software, close the SiTech software, and [[#Starting SiTech software| restart SiTech]] and all subsequent services.
6. '''Loss of dome comms'''. The symptom will be that the dome won't move to a new target, or that it has closed without warning (without parking the telescope or closing the mirror covers: those actions suggest an LCU shutdown). A red warning button will appear labelled "Bad Dome Comms" in the Dome GUI - clicking it should solve the problem. If it does, go to the browser TCS Advanced tab, and in the central panel click "TAKE CONTROL". If the dome had closed without good reason in the middle of observing, CLOSE the mirror covers, then turn dome "Tracking" ON, OPEN the dome then the mirror covers. If comms are not restored this way, then press Shutdown on the browser TCS and follow the full instructions on [[#Starting SiTech software| starting SiTech software]] to restart. Then reload the browser TCS and [[#Starting SiTech software| run the telescope startup procedure.]].
7. '''Focus is unresponsive'''. This is typically a comms loss to the SiTech focuser GUI and doesn't respond to the instructions in point 2. Follow the full instructions on [[#Starting SiTech software| starting SiTech software]] to restart.
