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. 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.
NOTICE:
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.

Exiting Mission Critical Geofence
When and where to use:
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 is canceled or you hear
a preprogrammed VA tone. The radio displays the new channel and a message is received to indicate
the changes.

6.18.1
Operating in Failsoft System
When and where to use:
The failsoft system ensures continuous radio communication during a trunked system failure. If a
trunking system fails completely, the radio goes into failsoft operation and automatically switches to its
failsoft channel.
During failsoft operation, your radio transmits and receives in conventional operation on a
predetermined frequency. You hear a medium-pitched tone and the display shows Failsoft.
When the trunking system returns to normal operation, your radio automatically leaves failsoft
operation and returns to trunked operation.
