Acts like the GC 2008, as an adapter between MHA-2 and hardwire communication units. The difference is that the GC 2010 permits the simultaneous use of both wireless and hard wire communication, without having to change from one to another.
By using the PTT communication is possible with both wireless receiving units and hardwired connected surface units. Without pressing the PTT, communication will be full duplex, hardwired only.
Receiving will always be activated for both wireless and hardwired (if connected).
