•Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
•Position your Kramer VP-426H2 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.
