fixes are difficult to obtain indoors, in covered locations, between high buildings, or in situations where
you have not established a clear broad view of the sky.
If adequate signals from multiple satellites are available, your GPS feature only provides an
approximate location, usually within 10 meters from your actual location, but sometimes farther away.
Sometimes, the GPS feature cannot complete a location calculation successfully. You will then see a
message indicating that your radio cannot connect to enough visible satellites.
To maximize the ability of your radio to determine a fix, take note of the following guidelines:
•
For your initial fix, hold the radio in the face position.
•
Stay in the open as the GPS feature works best when there is nothing between your radio and the
open sky.

mode is activated.

information received is saved as Emergency and Last Known Location respectively.

Mission Critical Geofence (ASTRO 25 Trunking)
This feature allows your radio to use the Global Positioning System (GPS) receiver to determine
its location at frequent intervals, and evaluate if the radio is within the Geofence area in real time.
Geofence is a virtual perimeter based on the GPS to define a geographical area on earth.
When your radio enters the predefined Geofence area, your radio receives the Dynamic Regroup
command from the system, and immediately connects to a Dynamic Regroup talkgroup. The radio
