2.1 Achieving the Best Performance

To achieve the best performance:

•Use only good quality connection 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-73 away from moisture, excessive sunlight and

dust
