Master is in monitor mode, other Substations cannot audibly call the
Master, but an LED lights above the corresponding Substation switch on
the Master for a period of 20 seconds.
Each Substation can call the Master by pressing the Call button. A
tone will sound as long as the Call button is pressed. Once the Master
responds by pressing the Talk button, the Substation can then talk hands free and the Master station
operator will need to press the Talk button to reply.
