Introduction
Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing
a world of unique, creative, and affordable solutions to the vast range of problems that
confront the video, audio, presentation, and broadcasting professional on a daily
basis. In recent years, we have redesigned and upgraded most of our line, making the
best even better!
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/VP-424C or
www.kramerav.com/downloads/VP-426C 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 neighboring electrical appliances that may adversely
influence signal quality.
•Position your Kramer VP-426C / VP-424C away from moisture, excessive
sunlight and dust.
Safety Instructions
Caution:
•This equipment is to be used only inside a building. It may only be connected to
other equipment that is installed inside a building.
•For products with relay terminals and GPI\O ports, please refer to the permitted
rating for an external connection, located next to the terminal or in the User
Manual.
•There are no operator serviceable parts inside the unit.
