Chapter 7: Advanced Features
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.

Mission Critical Geofence
This feature allows the radio to use the GPS receiver to determine radio location at frequent intervals and
evaluate if the radio is within the Geofence area in real time.
Check with your dealer or qualified technician to program the geofence coordinates and actions.
7.19.3
Entering Mission Critical Geofence
When and where to use:
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. The user 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), 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.

intelligent lighting, channel, or newly assigned talkgroup. Voice announcement is canceled or you hear a
preprogrammed VA tone. The radio displays the new channel and a message is received to indicate the
changes.
