materials for possible future shipment

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 

640T/640R 

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.
