2 WP-20 - Getting Started
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
Go to www.kramerav.com/downloads/WP-20 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 neighbouring electrical appliances that may adversely
influence signal quality
•Position your WP-20 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.
2.2 Safety Instructions DC

2.3 Shielded Twisted Pair/Unshielded Twisted Pair
Kramer engineers have developed special twisted pair cables to best match our
digital twisted pair products; the Kramer BC-HDKat6a (CAT 6 23 AWG) HDBaseT
certified, and the Kramer BC-DGKat7a23 (CAT 7a 23 AWG) cables. These
specially built cables significantly outperform regular CAT 6 and CAT 7a cables.
2.4 Recycling Kramer Products
The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC aims
to reduce the amount of WEEE sent for disposal to landfill or incineration by
requiring it to be collected and recycled. To comply with the WEEE Directive,
Kramer Electronics has made arrangements with the European Advanced
Recycling Network (EARN) and will cover any costs of treatment, recycling and
recovery of waste Kramer Electronics branded equipment on arrival at the EARN
facility. For details of Kramer’s recycling arrangements in your particular country go
