Dual radio operation

The TM9456/9356 can be installed and 
programmed as two radios, with one user-
interface. This enables you to switch between the 
radios, and access different features and 
channels on those radios (for example, channels 
that operate on different frequency bands). You 
can also toggle modes that enable you to receive 
and transmit on both radios at the same time.
Each radio in a system may be identified by a 
unique name, which appears before all channel 
and group labels.
The following topics are covered in this section:

dual radio display states and descriptions

radio controls in a dual radio system

about the foreground and background radio

switching between radios (changing the 
foreground radio)

monitoring more than one radio (dual receive)

dual transmit mode

repeater mode

about the lone worker feature

lone worker operation

lone worker messages and indicators

responding to a lone worker prompt

responding to a lone worker prompt
