How do you remove the SmartBar 2 User Interface (UI)?


I need to remove the UI from my SmartBar 2 to replace a DMX chip or send in the UI for repair. How do I remove it?


  1. Power off and properly follow lockout/tagout procedures to remove power from the SmartBar 2. If it's a portable unit you can unplug it from the outlet.
  2. Remove the screws that line the back edge of the SmartBar 2 on both the top and bottom. This allows the back cover to be removed from the chassis. The picture below references the placement of two of those screws on the end where the UI exists:
  3. Unplug the harnesses from the rear of the UI. Refer to the picture below for the proper harnesses to unplug:
  4. Remove the two screws holding the UI to the front of the SmartBar 2 chassis, and the UI should lift right off.
