Geofence (ASTRO
®
25 Trunking System)
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.
Entering 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), 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.
