FM/ISO can be a system for the wireless transmission of interpretation using infrared light or a wired system using cable for signal transmission. It is a simple system that enables interpretation to take place during discussion of delegates for a conference of two languages.

In combination with a microphone management system (such as Forumate IIP Microphone System), the system can provide the best possible communication facilities for organized events that need to use two languages. Each and every participant can use the microphone system to speak, and what he or she says will be translated simultaneously so that other delegates will be able to listen to translated language immediately.
