Master/Slave System
In the Master/Slave configuration, a Master station controls the talk-listen function of the Slave units
through external control wiring.
When the Master’s push-to-talk is not activated, the Slave stations are in talk mode allowing the Master to
monitor the Slave’s audio. When the Master’s push-to-talk is activated, the Slaves are in listen mode
allowing the Master to transmit audio to the Slave stations. The Slave’s push-to-talk is not operable, and
their operation is hands-free.
