Application Example
An employee in a retail shop uses the radio with the Top
button programmed to Call All Available. This employee is
trying to check if anyone took the back room scanner. The
employee presses the Top button followed by the PTT
button and asks “Does anybody know who has the
backroom scanner?”. Anyone, irrespective of their channel,
who is not already part of another conversation, will hear
this call and can talk back to the whole group of users (who
are tied up in the super channel group call) and provide the
needed information.
