* The software now decides, based on which grating is in use, which lamp to switch on once ARC is selected from the ''Exposure type'' drop-down list on the ''Exposure/CCD info'' pane.
* Alternatively, click on the appropriate lamp icon in the instrument schematic - this , where 1=CuNe and 2=CuAr. This will switch on the lamp and insert the arc mirror into the beam. Having taken the arc, simply click on the arc mirror icon in the schematic to remove the arc mirror and switch the lamp off. One can also control the lamps using the ''Lamp/Mirror Settings'' pane of the SpUpNIC Control GUI. Click the appropriate ''Change'' state button to switch the desired lamp on/off, and to move the arc mirror into the beam to take an arc exposure.
