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 VA-4H and away from moisture, excessive sunlight
and dust
This equipment is to be used only inside a building. It may only be
