What to do if the error message "Insufficient Bandwidth for Video Transmission" appears on the LiveU LU70?
- K

  This error appears when the LiveU unit detects that there is less than 128 Kbps free for broadcasting. If your Profile is currently set to Interview, try changing it to the minimum permitted delay using the slider. If your Profile is already set to the minimum permitted delay, try changing it to the maximum permitted delay using the slider. Also, try changing the physical placement of the LiveU TV Tuner unit by moving it closer to a window, where the cellular signal is typically better.
