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-88UT to check for up-to-date user manuals,
application programs, and to check if firmware upgrades are available (where appropriate).
Achieving 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 neighbouring electrical appliances that may adversely influence
signal quality.
Position your Kramer VS-88UT 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.

VS-88UT - Installing in a Rack
8
Installing in a Rack
This section provides instructions for rack mounting the VS-88UT. Before installing in a rack,
verify that the environment is within the recommended range:
Operation temperature –0to 40C (32 to 104F).
Storage temperature –-40to +70C (-40 to +158F).
Humidity –10% to 90%, RHL non-condensing.
When installing on a 19" rack, avoid hazards by taking care that:
It is located within recommended environmental conditions. Operating ambient
temperature of a closed or multi-unit rack assembly may exceed ambient room
temperature.
Once rack mounted, there is enough air still flow around the VS-88UT.
The VS-88UT is placed upright in the correct horizontal position.
You do not overload the circuit(s). When connecting the VS-88UT to the supply circuit,
overloading the circuits may have a detrimental effect on overcurrent protection and
supply wiring. Refer to the appropriate nameplate ratings for information. For example,
for fuse replacement, see the value printed on the product label.
The VS-88UT is earthed (grounded) and connected only to an electricity socket with
grounding. Pay particular attention when electricity is supplied indirectly (for example,
when the power cord is not plugged directly into the wall socket but to an extension
cable or power strip). Use only the supplied power cord.
To rack-mount the VS-88UT:
1. Attach both rack ears to the VS-88UT:
Remove the screws from each side of the VS-88UT
(5 on each side), and replace them through the rack
ears.
2. Place the rack ears of the VS-88UT against the rack
rails and insert the appropriate screws (not provided)
through each of the four holes in the rack ears.
Some models, may feature built-in rack ears:
Detachable rack ears can be removed for desktop use.
Always mount the VS-88UT in the rack before connecting any cables or power.
If you are using a Kramer rack adapter kit (for a machine that is not 19"), see the Rack
Adapters user manual for installation instructions available from our Web site
www.kramerav.com/downloads/VS-88UT.
