Problem:
You only have one RC4 system but you suspect there might be another one operating nearby.
Solution:
If you are using anRC4Magic system, this is not a problem. Every system uses a unique System ID. other systems operating nearby will be using their own ID. A large number of RC4Magic systems — 15 or even more — can operate in the same space without interference. And systems that are more than 300 feet away are out of radio range and are not sharing bandwidth with you at all.
The one exception to this is when two nearby systems are both operating on the Public ID. In that case, interference WILL occur if they are within 300 feet of each other. Avoid this by not using the Public ID unless you are combining your system components with someone else’s and only ONE transmitter is being operated. Use your unique System IDs and interference is virtually impossible. We’ve designed the system that way. This is why RC4Magic works so well.
