2.1 Achieving the Best Performance

To achieve the best performance:

 Use only good quality connection cables (we recommend Kramer high-

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-24HC away from moisture, excessive sunlight and

dust
