Mission Critical Geofence (ASTRO
®
25 Trunking)
Entering the Geofence Area
The Voice Announcement and TMS display in this feature are optional. They must be configured to enable you
to hear and see these indicators.
When the radio enters a Geofence area, the radio immediately sends a message
ACK
back to the system.
The radio searches the current zone for the channel with same talkgroup assigned as the Dynamic Talkgroup
and also with same system ID of current trunk system. Once matched, the radio display shows the first
matched and connected channel alias.
If there is no channel with matching Talkgroup ID and trunk system ID, the radio display shows the channel
alias of
<DYNAMIC talkgroup>
.
Once the radio is connected, you hear a dynamic regroup tone, the radio display shows
<DYNAMIC
channel>
with the temporary green color intelligent backlight and you hear a Voice Announcement.
Note:
When the radio loses the GPS signal, the GPS icon blinks and the radio sounds two highpitched tones
repetitively to indicate that the GPS has failed to operate. The radio display shows the red intelligent light.
If the first matched channel is not configured with Voice Announcement, no Voice Announcement is played.
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 user presses exit/home to exit this screen.
