Troubleshooting Reception Problems

While we have tested the Wireless Vantage Pro2 radio extensively, each site and each installation presents its own issues and challenges. Obstructions, particularly metallic ones, often cut down your station’s reception distance. Be sure to test reception between the console and ISS, in the locations you intend to install them, before perma- nently mounting your ISS or other transmitter(s).

The console’s reception status displays at the lower right corner of the screen.
