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 and position your Kramer
