Note: If the radio is set to local mode (LOC), remote control commands will 
be refused. Local mode has the highest priority and interrupts any remote 
control fixed sessions. Parameters can only be monitored remotely when 
the radio is in local mode. 
When the radio is in the local mode, you can connect a headset and power 
up the transmitter by pressing the PTT key at any time. 
In the receive mode, the front-panel receive audio signal is always audible. 
In other words, the internal loudspeaker and the headset audio connector 
are always active and the volume of the two can be controlled by the 
assigned potentiometer. 
Note: The local mode causes the termination of all active VoIP connections 
if the parameter “Line Interface in Local” mode is disabled. As long as the 
radio is in local mode, all VoIP connection requests are rejected. 
All parameters and measurements can be displayed in the remote and local 
modes.
