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
Go to www.kramerav.com/downloads/VS-88DT
to check for up-to-date user manuals, application programs, and to check if firmware
upgrades are available (where appropriate).
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-88DT 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.
Safety Instructions
Caution: There are no operator serviceable parts inside the unit.
Warning: Use only the power cord that is supplied with the unit.
Warning: Do not open the unit. High voltages can cause electrical shock! Servicing by
qualified personnel only.
Warning: Disconnect the power and unplug the unit from the wall before installing.
Using TP cables
Kramer engineers have developed a special twisted pair cable to best match our HDBaseT
products, the Kramer BC−HDKat6a (CAT 6 23 AWG) cable. This specially built cable
significantly outperforms regular CAT 5/CAT 6/CAT 7a cables.
