The VP-727A-BA:

Achieving the best performance means:
•
Connecting only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low quality cables)
• Avoiding interference from neighboring electrical appliances, making sure
not to block the ventilation holes, and positioning your VP-727A-BA away
from moisture, excessive sunlight and dust
