Anyway, there was a setup going on in the arena at the time, so we had to use a "special" entry method to get inside the display. Normally, the display is lowered to the floor and can be accessed with a ladder, but we used a series of ladders and swaying catwalks about 85 feet in the air, over open space, to make the trip.
Here are some images which might be interesting.
The big overall view of the arena. The small box atop the blue curtains (part of the show which was ongoing) is the display system and scoreboard.
Kind of gives an idea of the scale of this thing. The display itself has enough square footage inside to park about 4 cars. Note the aluminum catwalk which has been lowered like a gangplank into position for access to the top of the system.
After climbing down a 15 foot ladder from the catwalks in the rafters, you can stand on the swaying temporary catwalk and enjoy this view of the top of the display system. Notice the cluster of loudspeakers in the center of the display unit. They are separately lowerable, so that they may be placed at the right height for either servicing on the floor or put in use from about the position where they are now. The display housing is hollow in the center, allowing the speakers to pass down through if needed.
Here is a view from the swaying catwalk down about 18 feet of ladders into the temporary work area inside the display system. Note the chair and one worker at the bench.
Inside the unit, you can see one wall in this view, note the many data cables and the ladder we used to reach the higher units.
The temporary workbench with a unit being burned in prior to recalibration.
here we are on the swaying catwalk, heading back towards that 15 ft. climb up into the superstructure, after a day's work. It's pretty dark up there, but there was enough light to see the ladder and the railings.
