2 TBUS-3xl - 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
• Use Kramer high-performance high-resolution cables
i
Go to http://www.kramerelectronics.com to check for up-to-date
user manuals, a complete list of Kramer wall plates and module
connectors, 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)
• Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
• Position your Kramer TBUS-3xl away from moisture, excessive sunlight and
dust
