2.1 Achieving the Best Performance

To achieve the best performance:

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 neighbouring electrical appliances that may adversely

influence signal quality

• Position your VM-4H2 away from moisture, excessive sunlight and dust
