materials for possible future shipment

user manuals, application programs, and to check if firmware

2.1 Achieving the Best Performance
To achieve the best performance:
• Use only good quality connection 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 VP-4x8 away from moisture, excessive sunlight and
dust
