Operating Manual 6175.4760.02 – 01 3.35
M3SR Series 4100 Control and Monitoring of Radio and Control Unit
3.3.1.3 Session Types and Access Rights
A radio can have up to 3 sessions at a time with control units connected to it. Only one control
unit can have a session with operational access right, which gives it the right to manipulate
settings of the radio..
Up to three control units (one of them is the local control unit) can have sessions with mon-
itoring access right, allowing them to monitor the radio at the same time.
Figure 3.19 illustrates the access rights available in a radio if no control unit is connected.
