Two internal dip switches activate four different modes that are activated by using the call signaling function of another station to allow individual control of the speaker and microphone.
The 4-wire optional daughter board converts the station to accept 4-wire connections, allowing the station to operate via fiber optic cable and other 4-wire devices over longer distances.
