Monitoring the Communications of Control Heads (Transmit Audio Monitor)
Transmit Audio Monitor
is the function to monitor the audio of the transmitting Control Head by the speaker of the other
Control Head when transmitting on the connected Control Head 1 and Control Head 2. The function is for Dual Control
Head. The conversation can be heard even if the 2 Control Heads are at remote locations. Also, by using the Talk Interrupt
function, one Control Head can send notifications such as a request for stopping transmission to the other transmitting
Control Head by voice, and the Talk Interrupt function can be used for transmission during an emergency. Also, the voice
communication can be monitored by the external speaker connected to the Selected RF Deck.
The transceiver behaves as follows according to the configuration in
Transmit Audio Monitor
(Disable, w/o Talk Interrupt,
w Talk Interrupt):
0
Disable
This configuration value is the default configuration value, and basically the behavior is the same as the behavior of normal
transmission. The audio of the transmitting Control Head cannot be monitored by the other Control Head when transmitting.
0
w/o Talk Interrupt
The audio of the transmitting Control Head can be monitored by the other Control Head when transmitting. The displays of
both Control Head 1 and Control Head 2 are in the normal state while transmitting.
