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 DIP-31 Automatic Video Switcher 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.
