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)

•Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
•Position your Kramer VP-28 away from moisture, excessive sunlight and
dust
This equipment is to be used only inside a building. It may only be
