The system sends a message to your radio. The radio display shows a direct text message content
without any user operation. This message indicates that you are currently present in a Geofence area.
This TMS remains open on the display until you press exit/home to exit this screen.
NOTE:
If there is another incoming text message before you exit the previous message, the
message screen is refreshed to show the latest message.
When the radio exits the Geofence area, your radio reverts to original channel or
newly assigned talkgroup. The radio display shows the new channel together with Voice
Announcement to indicate the changes. Voice Announcement of the new channel only works if
that channel is configured with Voice Announcement.

Entry to Mission Critical Geofence
When the radio enters the predefined Geofence area, the radio displays
<Geofence Alias>
with
the intelligent backlight and you hear a Voice Announcement. Zone and channel alias of the Geofence
area is displayed.
If the radio is set to manual, you can choose either to proceed with zone and channel change or cancel
the change.
The radio then connects to the designated talkgroup. The radio displays the talkgroup alias and
dynamic regroup tone sounds. The transmit power level changes and the radio shows a direct text
message content without any user operation.
NOTE:
The availability of the Voice Announcement (VA), Text Messaging Service (TMS) display,
Intelligent Backlight, and Transmit Power Level alerts depend on your radio configuration. The
VA can be programmed to alert continuously or momentarily.
If Site Selectable Alert (SSA) is enabled, the radio mutes any alert that is received when
entering the Geofence area and unmutes when exiting.
17.3
Exit from Mission Critical Geofence
When the radio exits the Geofence area, the radio reverts to the original transmit power level,
intelligent lighting, channel, or newly assigned talkgroup. Voice announcement (VA) is canceled or
you hear a programmed VA tone. The radio displays the new channel and a message is received to
indicate the changes.
