Troubleshooting Guide - Vector Power On Board VEC031POB Owner's Manual & Warranty Information

Television Interference:
The Vector Power-On-Board™ 400 is shielded to minimize interference
with TV signals. However, in some instances, some interference may still
be visible, particularly with weak TV signals. Try the following corrective
measures:
• Position the inverter as far as possible from the television, the antenna
and the antenna cables. Use an extension cable, if necessary
• Adjust the orientation of the inverter, the antenna cables and the TV
power cord to minimize interference
• Make sure that the antenna feeding the television provides an
adequate ("snow free") signal and that high quality, shielded antenna
cable is used
