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

Go to http://www.kramerelectronics.com 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 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 products away from moisture, excessive sunlight and

dust
