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 TP-121xl and TP-122xl away from moisture, 
excessive sunlight and dust 
This equipment is to be used only inside a building. It may only be
