field operation.

To achieve the best performance:

• Use only good quality connection cables

• Avoid interference from neighboring electrical appliances that may

adversely influence signal quality and position your Kramer VP-423

away from moisture, excessive sunlight and dust

to avoid interference,

deterioration in signal quality due to poor matching, and elevated noise

levels (often associated with low quality cables)
