* If the main user interface and quick-look interfaces are not running, they may be started from the panel on the left edge of the screen. The main user interface is started with the icon of an absorption spectrum, and the quick-look interface from the icon of an emission spectrum.
* Fill in target information (optional).
* Set the focus required (or use the Hartman Hartmann routine; see the Advanced User Guide).

* Ensure that the grating you require is inserted, and set the grating angle.
* Select the required filter (or leave the filter open).
* Select the acquisition exposure type (ARC, BIAS, SCIENCE, FLAT, TEST)
* If appropriate, set the exposure time and number of exposures.
* If taking a science image, acquire the target, and ensure that it is visible through the slit.
* If taking an arc, ensure that the arc mirror is in-beam, and the chosen arc lamp is on (remember to turn off the arc lamp and move the arc mirror out of beam when done).
* Start the acquisition exposure with the Expose button
* The countdown timer will show the time remaining, and the progress bar will first show the exposure completion state, and then the readout state.
