Group calls to Callout group
Note:
While your radio is in Protected Callout Mode the only calls you
can make are TETRA Alarm Calls, Quick Calls (if customised as a higher
priority than Callout), and, if allowed, group calls to the Callout group.
You can only make group calls if PTT use is permitted during the Callout.
For some Callouts your radio can make and/or receive group calls to a
specially configured
Callout group
when it is in Protected Callout Mode. This
group may be the group the radio is attached to when the Callout is received,
or a different group which the radio is configured to connect to on receipt of
the Callout or when an acceptance message is sent.
While the PTT is pressed and the radio is transmitting the text “Talk” is
displayed in place of “CALLOUT” on the Radio Status Line at the top left of
the screen and no backdrop is displayed. When the radio is receiving a group
call the ISSI (or shortened ISSI) or identity of the transmitting party is
displayed in place of “CALLOUT” on the Radio Status Line at the top left of
the screen.
When the Callout has exited, depending on the customisation, the radio
either reattaches to the group it was attached to before receiving the Callout,
or remains attached to the new group.
Information Phase
Some Callouts do not exit after the initial acknowledgement is sent, but enter
an Information Phase when information may be
sent to and
received
from the originator of the Callout. Information can include a pre-set message,
a free-form text message or a Callout group call. Your radio can also be
customised to display a backdrop graphic to indicate it is in Information
Phase.
When information is sent (for example “Will Respond”) it is displayed and
the
information sent icon displays.
Press the
Exit
context key to exit from the Callout or the
Respond
context key
to use an option on the Information screen or press a Left or Right
navigational key to display a menu of further options.
