2  Getting Started 
We recommend that you: 
•  Unpack the equipment carefully and save the original box and packaging 
materials for possible future shipment

Go to http://www.kramerelectronics.com to check for up-to-date  
user manuals, application programs, and to check if firmware 
upgrades are available (where appropriate). 
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 VS-88DVI 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.
