== How to close the roof without breaking the telescopes ==* Park ==== First put the telescopes using in a safe position ==== Try the following steps, in this order, until the telescopes are in a safe position, i.e. approximately horizontal.* Run the command " ''slew stow" '' in any terminal window on the TCS machine (computer keyboard/screen nearest the door). The username/password is written on the white board. * If this command does not work, try the command "park"in any terminal window.
* Check that the telescopes are out of the way of the roof. If not, use a 13mm spanner to loosen-off the RA and Dec drive clamps and move the telescopes to a safe position by hand. Remember to tighten (but don't over-tighten) the drive clamps afterwards. There is a tool box on the floor in the mount room.

Try the following steps, in this order, until the roof is closed.
