Each of the eight 'bump buttons' have two functions: in the Normal mode, the bump button takes the associated fader to 100%. In the Patch mode, the bump button patches the DMX dimmer address shown in the dimmer window to the associated fader, while an additional bump button, labeled Unpatch, is for unpatching DMX addresses. Unpatched, the level sent to these dimmers is zero. Last and Next buttons are located below the dimmer display, for selecting the next or previous dimmer, and are only active in the Patch mode. More information is available from the website below.
