To achieve the best performance:
•Use only good quality connection cables1
•Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your
VS-121HC 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)
