2  Getting Started 
We recommend that you: 
• Unpack the equipment carefully and save the original box and packaging 
materials for possible future shipment 
• Review the contents of this user manual 
Use Kramer high performance, high resolution cables 
• Use only the power cord supplied with the device 
Go to http://www.kramerelectronics.com to check for up-to-date  
user manuals, application programs and to check whether firmware 
upgrades are available (where appropriate). 
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 too tightly or too loosely. Leave a small amount of 
slack 
• Avoid interference from neighboring electrical appliances that may adversely 
influence signal quality  
• Position your Kramer VS-808TP away from m oisture, excessi ve sunlight and 
dust 
2.2  Using Twisted Pair Cable 
Kramer engineers have developed special twisted pair cables to best match our 
digital twisted pair products; the Kramer: BC-DGKat524 (CAT 5 24 AWG), the 
Kramer: BC-DGKat623 (CAT 6 23 AWG cable), and the Kramer: BC-DGKat7a23  
(CAT 7a 23 AWG cable). These specially built cables si gni ficantly outperform 
regular CAT 5/CAT 6/CAT 7a cables.
