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

•Avoid interference from neighboring electrical appliances that may adversely

influence signal quality

•Position your Kramer VA-4H and 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.
