grounding and specifies that the cable ground shall be connected to the grounding system of the
building, as close to the point of cable entry as possible.
Unpacking and Inspection
Each unit is shipped factory tested. Ensure all items are removed from the container prior to discarding any
packing material.
Thoroughly inspect the unit for shipping damage with particular attention to connectors and controls. If there is
any sign of damage to the unit or damaged or loose connectors contact your distributor immediately. Do not put
the equipment into service if there is any indication of defect or damage.
Hardware Installations and Connections

intelligently designed to detect the video input from the video source.
HDMI Connection: Connect the HDMI cable from the video source into the HDMI input.
If using a Component Video Cable, connect the Y (Green), Pb (Blue), and Pr (Red) video source
cable to the unit’s Component input port.
If using a Composite Video source, use RCA connectors to connect the video source (e.g., CATV,
DVD, VCR, Camera) to the unit’s CVBS port.
2. Composite Audio input: Connect A/V audio source (Left / Right Audio, the red / white AUDIO L and
AUDIO R) to connect the audio source to the 3.5mm Audio L/R phone jack.
3. Use a quality 75Ω coaxial cable with “F” connectors from the unit’s RF Output.
4. Connect the included power adapter to the unit’s POWER plug.
5. Connect the power adapter to an appropriately rated AC power outlet.
