FFCS/L provides the interface to the system for two of the vehicle crew members, allowing each crew member to have independent control of the communication options and the volume of the connected headset. A digital noise tracking VOX and the use of Active Noise Reduction (ANR) headsets ensures high intelligibility under high noise environments.

The compact nature and two independent user capability is ideal for vehicles with limited space such as HMMWV's and Land Rovers.

It provides the user with access to two intercom channels and up to six onboard radio transceivers. The two intercom channels allow vehicular crew to be independent of infantry crew allowing two independent full duplex intercom channels in the vehicle.

Transmission on the selected 'work' channel is enabled by the push-to-talk (PTT) switch mounted on the headset.
