The embedded internal disc should slope upward toward the front of the cabinet, not toward the back. The dome is not affixed to anything and held in place with gravity. It should be cafefully set aside if the top LCD needs to be moved. The dome can be cleaned with simple window cleaner and a fine cloth. It should be fairly low maintenance.

The LCD display should face upward into the dome. It should be rotated 90 degrees counter-clockwise for maximum brightness. The connected “Rotating Box” hardware device will compensate for the rotation since it is not possible in the display’s settings. The LCD’s polarizer prevents the screen from outputting a very bright reflection in the default orientation. The LCD display is not affixed to the top of the cabinet and is only held in place by it’s sheer weight. Care should be taken when moving the cabinet as not to push the LCD off of the top. The dome should always be carefully removed when manipulating the LCD display.
Dome and Top LCD
A black plastic mask blocks out the edges of the display and can be removed if needed by sliding the pieces away and lifting them out.
R5066-32UK Rack Tower 32U Black 600x600mm
This is a very heavy-duty A/V rack. It has wheels and screw-down rubber stoppers on the bottom. The stoppers should always be engaged when the rack doesn’t need to be moved. doors and side panels can easily be removed from the cabinet and set aside. I prefer seeing the cabinet without the doors but with the panels on. However, the doors might be best to put on for storage and transporting the piece.
Panasonic WV-BM503 Video Monitor
These are standard observation monitors that use BNC connectors on the back. There are controls on the front for the picture and for power. I would advise leaving them in the “on” orientation at all times and just use the cabinet’s power strip button to turn them off with everything else that is attached to the strip.
These monitors are secured to the cabinet rails with 10/32 rack screws.
Panasonic TR-930U B&W Video Monitor 120V. See above (5” Monitors (3x)) regarding contols and power. These monitors are secured to the cabinet rails with 10/32 rack screws.
Monitors and Television configuration
Vintage Sears SR 1000 Series 1988 19” Color TV
This television should sit on its side with the knob controls at the bottom. It’s a color television, so most of the content that will appear on it will be in vivid color. It can turned on by twisting the small “Volume” knob until a “click” is heard/felt. The television should be left in the “on” state at all times and power can be controlled with the rack power switch at the back of the cabinet.
While it does have a speaker, the TV’s volume knob should be keep low to avoid an annoying hum. The television is not held in place and is only using its own weight to stay in place. Because of this, care should be taken when moving or transporting the piece.
This connects to the television’s coaxial-in connector on the back of the TV. The number on the display corresponds the the UHF knob on the front of the television. The UHF knob (on the left in sideways orientation) is the one with many more numbers than the other knob. Sometimes the knob might be turned to the left and back to correct for interference. This is normal with old TVs.
RF Modulator
2018 Intel Mac Mini 32GB Ram
The Mac Mini is the brains of the piece and is inside the drawer at the back of the rack. The Mac Mini should not be connected to the cabinet’s power strip but should connected directly to wall power separately. The Mac Mini is set-up to restart itself every night on a schedule to help avoid memory issues. The display components connected to the Mac Mini branch out from the Thunderbolt connector and not the HDMI. The Thunderbolt connector is marked with bright pink tape.
