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 neighbouring electrical appliances that may

adversely influence signal quality

Position your VM-4UHD away from moisture, excessive sunlight and dust

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

connected to other equipment that is installed inside a building.
