The *0## command de-registers the radio. Typically, this is automatically performed when powering 
down the radio. Using this method, the User ID is remembered by the radio so only the password is 
needed at next log-in. Log-off manually by pressing *0##. 

As illustrated in Figure 8-4, a personality defines the profiles and talk groups available to the user. It is 
the structuring of a collection of profiles and privileges established by the OpenSky network administrator 
to provide the user with a comprehensive set of profiles to communicate effectively with the necessary 
talk groups or individuals. 

Personalities are stored on the network and downloaded over-the-air to the radio. This process is called 
“provisioning.” Provisioning occurs at radio power-up (if the personality is not already stored in the 
radio’s memory) and at user log-in. When changes are made to the personality, the radio is automatically 
re-provisioned. Each personality can contain up to sixteen (16) profiles and each profile can contain up to 
sixteen (16) talk groups. 

As stated above, each profile can contain up to sixteen (16) talk groups. A profile also defines the radio’s 
emergency behavior. All transmissions are made on the selected talk group (displayed on the top line of 
the dwell display). The user can change the selected talk group to any of the other talk groups within the 
profile. 

 

TG = Talk Group 

 

A talk group represents a set of users that regularly need to communicate with one another. There can be 
any number of authorized users assigned to a talk group. Talk groups are established and organized by the 
OpenSky network administrator. An OpenSky talk group is similar to a channel within a conventional FM 
radio system.
