The operation of the V-R82P is fairly straightforward, however, it is important to take note of the following:

1. The V-R82P has been designed to fit in a 4U space on your rack. It may be necessary to center the unit up or

down in order to not touch any adjacent units in your rack when tilting unit up or down.

2. Each LCD Panel comes with a protective plastic film that must be removed by carefully lifting the film from

the corner and peeling it off. Be certain not to apply any pressure on the LCD panels, they are fragile and can

break. Scratched, cracked or broken LCD screens are not covered by our warranty.

3. The V-R82P uses 12VDC, 3.0amp regulated power. Be certain that these specifications are met when using a

power supply other than the one supplied to you by Marshall Electronics.

4. The center pin on the coaxial power connector for the V-R82P is the POSITIVE terminal and the outside ring is

NEGATIVE. Any battery operation of the V-R82P must have this polarity configuration.

5. The Video inputs on the rear of the panel are 75 Ohm self-terminated. The loopthrough feature uses active

components and is always active as long as power is supplied to the unit regardless of the monitor being ON or

OFF.
