Geofence Mode

(Trunking System, ASTRO 25)

Selects for additional Dynamic Regrouping functionality, which is triggered when a radio enters a Geofence. This has the benefit of minimizing radio-user interaction with the radio as it enter locations requiring the use of a pre-determined Talkgroup, for example when entering a dangerous area of a mine. This selection applies for the current ASTRO 25 Trunking System.

In the event of a loss of the GPS signal, the radio generates a repetitive tone to alert the radio-user (see also GPS Fail Tone Interval).

When the System Type field is set to "ASTRO 25", and

when the radio is model / option capable.

DEFINITIONS:

"Disabled":

Geofence functionality is disabled.

If the radio receives a Dynamic Regrouping command, it will handle it in the customary manner.

"Automatic":

When the radio receives the Dynamic Regrouping command from the FNE, as a result of entering the pre-defined Geofence, it automatically moves to the Dynamic Regrouping Channel, a "gurgle" alert tone is sounded, the regrouped Channel Name temporarily appears in the display (see Temporary Message Display Time), and the CPS-defined Voice Announcement sounds to indicate the change.

The radio first searches the current zone (that the radio has moved to) for the first channel with the same Trunking Talkgroup assignment as the Trunking Talkgroup which was dynamically assigned by the referenced Trunking System, then shows the Channel Name of the first matched channel on the display. If no matching channel is found, the radio shows the Channel Name of the channel position which is assigned as the "DYN" target channel for the dynamic regrouping command (with green intelligent backlighting for models which support Intelligent Lighting).

The radio also searches the current zone for the channel with same Trunking Talkgroup assignment as the Trunking talkgroup which was dynamically assigned by the referenced Trunking System, and then plays the Channel Announcement assigned to the matching channel. If no matching channel is found, the radio plays the Channel Announcement (if there is one) assigned to the channel position which is assigned as the "DYN" target channel for the dynamic regrouping command.

The TMS (Text Messaging Service) Server may also be configured to send a TMS notification to the radio, the content of which appears directly in the display (without radio-user interaction) when the Direct TMS Content Display field is enabled.

Once the radio has moved to the Dynamic Regrouping channel, radio operation behaves in the customary Dynamic Regrouping manner.

The radio remains on this Dynamic Regrouping channel until the radio exits the Geofence; at this point, the FNE cancels Dynamic Regrouping (or re-assigns the radio with another Dynamic Regrouping command), and the radio automatically returns to the zone and channel that were being using before the radio was dynamically regrouped (or is correspondingly re-assigned).
