Installation Steps

1.Turn the display off completely, using the hard on/off switch, or disconnect the equipment fully from the main power supply.

2.The receiver must be placed in the plug-in slot designed for this purpose. It is located on the left side of the display near the carrying handle.

3.Remove the carrying handle by loosening the two Phillips-head screws.

4.Remove the cover panel over the plug-in slot by loosening the two Phillips-head screws.

5.Ensure that the receiver is inserted wtih the right orientation. Orientation is correct when the tuning port is on top and the connector labeling is not upside down.

6.Use the screws that previously held the cover panel in place to secure the receiver.

7.Re-attach the carrying handle. Ensure that the screws are properly tightened (1.39 – 1.89 Nm torque).

8.Connect the CATx cables between the system ports of the Broadcaster and the Receivers.

2.Tuning: In order to achieve the best possible picture quality, you must tune the system. You can tune the system from the Transmitter position or from the Receiver itself. By tuning from the Receiver, you have the advantage of being able to see the tuning, right on the screen. To tune from the Broadcaster position, please see the Transmitter‘s user guide; to tune from the Receiver‘s position, connect the Serial Download cable to the Receiver Tuning Port and the Serial port of a computer that carries the Service Utility. See Figure 1 below.
