performance, high-resolution cables) to avoid interference, deterioration in

signal quality due to poor matching, and elevated noise levels (often

associated with low quality cables)

Do not secure the cables in tight bundles or roll the slack into tight coils

Avoid interference from neighboring electrical appliances that may adversely

influence signal quality

Position your Kramer VM-4HDxl away from moisture, excessive sunlight and

dust

This equipment is to be used only inside a building. It may only be

following:

1. Connect an SD/HD/3G HD-SDI video source (for example, an SD/HD/3G

HD-SDI camera) to the INPUT BNC connector.

2. Connect up to four video OUT BNC connectors to the appropriate

SD/HD/3G HD-SDI video acceptors (for example, SD/HD/3G HD-SDI

displays).

You do not have to connect all outputs.

3. Connect the 5V DC power adapter to the power socket and connect the

adapter to the mains electricity (not shown in Figure 2).
