When Relay-Mode is active, transceivers participating in the relay shall display the RLY indicator in both
their Dashboard-View and Active-Transceiver-View. The Active-Transceiver-View for a transceiver in
Relay-Mode is depicted in Figure 38. This figure illustrates a relay between RT2, RT4, and RT5. Note
that RT4 is receiving and the received message is being retransmitted on RT2 and RT5.

Once a relay is established, only the subset of transceiver functionality described in Table 7 shall be
available in the Active-Transceiver-View of a transceiver participating in the relay. Transceivers not
participating in the relay shall continue to operate normally.
Channel changes shall be disabled for a transceiver in Relay-Mode, therefore, the flip-flop button shall be
hidden and the channel number and channel alpha fields shall not be focusable. The standby-channel
shall be hidden and “Relay Active” shall be displayed in its place.

Exiting Relay-Mode can be achieved by invoking the Relay-Configuration dialog and pressing the
“Terminate” button.
6.4.2.4 Simulcast Mode
Simulcast Mode allows the operator to simultaneously transmit on multiple transceivers within the PMR
whenever the specified PTT is asserted. Any of the five PTT discrete inputs can be used as the simulcast
trigger, and all five transceivers can participate in the simulcast. For example, if a Simulcast is
established for transceiver-1 and transceiver-2 using PTT-1, and the operator keys up using PTT-1, the
operator’s transmission will be sent out both transceiver-1 and transceiver-2.
