# Click the '''STARTUP''' button on the bottom right of the screen. This will switch on the slew lights so you can watch it open the dome, baffle and mirror covers, and set the dome to follow the telescope, then switch off the slew lights. A blue progress circle will rotate on the button while all the commands are executed - don't try to do anything else until it disappears, indicating that the startup procedure is complete.
# On the TCS "Controls" tab, check that the '''Instrument''' you require is selected (highlighted in green to the mid-left of the display), and if not, click either SHOC or SIBONISE. SHOC is automatically selected on startup.
# On the central panel of the TCS "Controls" tab, check for green indicators showing the status of each subsystem: Mirror covers = Open; Secondary & Tertiary mirror motors = Auto; Dome: Control = TCS and Tracking = On; and the relevant rotator for your chosen instrument Tracking = On and Motors = Auto.
