/* The Observing Floor */
* '''XY-slide reset button on the grey box.''' On the top of the grey box with the emergency stop button is a small blue button to press if the TCS XY-slides fail to respond.
* '''PC monitor to the right of the North pier.''' This screen displays pointing information, including your target coordinates and current telescope coordinates, for use when slewing the telescope manually.
* '''Observing Floor Control Panel.''' On the North wall by the North pier there is a grey box labelled "Dome Shutter and Windblind Control", which has red buttons for opening/closing the dome shutter and raising/lowering the windblind. One must first switchon the telescope power (blue console) and press the top button labelled "Request Local Control" to activate the panel. The redindicator will illuminate when the panel is active. To open/close the dome, push and hold the appropriate button until the shutters stop moving and you hear a beep. To raise/lower the windblind, push and hold the appropriate button until the blind reaches the desired height. '''Do not raise the windblind while pointing into the wind; first rotate the dome by 180°, raise the blind then rotate back. '''There is also a switch for the upper dome lights.
* '''Dome flat lamp switch.''' On the North wall, just above and left of the monitor, is a dimmer switch that controls the incandescent lamp used for taking dome flats.
* A red '''balance weight''' on a rope, which can be hung from an appropriate place below the primary mirror cell if the telescope jumps while tracking (usually when tracking around the zenith).
