===Camera Issues===
* '''Camera won't switch on:''' If the camera display times out when trying to switch on, you will need to restart the services. To do this:
** Open a terminal. This is available from the top menu or side menu of the thin client in the warm room. If the web browser is full screen, push 'F11', and you should then see the top menu bar. Once the terminal window appears, ssh to the instrument by running the command
*'''Camera overheats:''' Should the camera over heat (this normally results from the air outlets being blocked), an alarm will sound from the camera. Unfortunately no indication or reason for the alarm will be given on the control software. In the case of this happening please shut the instrument down and contact electrical support immediately. THE CAMERA MAY NOT BE USED WHILE THE ALARM IS SOUNDING.
===GPS Issues===
* '''The GPS time is not valid:''' If the GPS reports that the timing is not valid, check that it is able to see at least a few satellites, and that the signal quality is acceptable. Click on the Receiver Status button on the GPS tab, and a pop-up should appear, displaying the signal quality of the visible satellites. If each signal quality bar is zero, check that the dome is open; the antenna can't detect the satellites if it's closed. If there are a number of satellites visible, each with a reasonable signal, you might need to wait for a while for the GPS to rgister this and for the time to become valid. Normally this happens quite quickly, but for reasons we don't entirely understand, sometimes this can take five or ten minutes.
=== Rescuing Data===
N. B. It is NOT normally necessary to run the data rescue script described below; the problem we had with the interface freezing up and acquisitions not being completed is now solved.
