The PRS-M3DT status LED is located on the side of the PRS-M3DT facing the rear of the DJI M3D/T. The LED colour on the PRS-M3DT indicates the stage of the flight. ## PRS-M3DT Status Indications:

## MTD Interface and Info Screen: Note that two different user interfaces are presented here.

The second, at bottom, is the interface seen when connecting to the DJI M3D/T through the DJI FlightHub 2 application.

Interface/Info Screen If Using DJI FlightHub 2


PSDK Interface	The PSDK interface will show the AVSS PRS-M3DT user interface. This will allow access to the INFO screen for information on the PRS-M3DT, as well as the MTD function of the DJI M3D/T transmitter (or DJI FlightHub 2). The Icon will appear white until the user clicks the icon. This will activate the PSDK window, and turn the icon yellow (blue on DJI FlightHub 2). Note: if the PSDK interface is not displayed on the Drone Transmitter, the PRS is not connected. Please check the installation instructions.
Info	The info button will display the status messages window.
Status Messages	The status messages window will allow the user to consult the DJI M3D/T transmitter or DJI FlightHub 2 for information on the PRS-M3DT system's health and functionality. This screen will also display the MTD countdown.
Deploy	The deploy function will allow the user to manually trigger the PRS-M3DT. This button will need to be pressed for three (3) seconds to activate the FTS and the MTD. The status messages screen will also display the MTD countdown. Note that the PRS-M3DT must first be armed through the configuration menu (see below) for the MTD to work.
Config.	When using firmware version 3.6.4 or later, it will allow the user to arm the PRS-M3DT (see below). The configuration function is accessed either through the three dots at the top of the DJI M3D/T transmitter's main screen, or through the gear symbol in the middle of FlightHub 2's main screen.

### Arming/Disarming {% hint style="danger" %} THE PRS-M3DT MANUAL TRIGGER DEVICE CANNOT BE ARMED UNLESS A HEIGHT OF 5 METRES (16.4 FT) AGL IS REACHED. {% endhint %} {% hint style="warning" %} IF ANY WARNINGS ARE PRESENT, THE PRS WILL NOT ARM. ALWAYS ENSURE THAT ALL WARNINGS DISAPPEAR BEFORE TAKEOFF. NOTE: IF THE PRS IS ARMED AND AN ERROR OCCURS, THE PRS WILL REMAIN ARMED. IF THE ATS HAS AN ERROR, THE ATS WILL DISARM, BUT THE MTD WILL REMAIN ARMED. CHECK THE ARM STATUS OF THE PRS TO VERIFY WHICH FUNCTIONS ARE ARMED. SEE PRS ARMING FLOW DIAGRAM BELOW. {% endhint %}

{% hint style="warning" %} IF THE GROUND DISTANCE SENSOR DETECTS A DISTANCE ABOVE GROUND OF LESS THAN OR EQUAL TO 5 METERS, THE PARACHUTE WILL BE TEMPORARILY DISABLED AND WILL NOT TRIGGER. NOTE: THIS CAN OCCUR IF FLYING DIRECTLY ABOVE A BUILDING, TREE, OR OTHER OBSTACLE WITHIN 5 METERS. THE PSDK TEXT WINDOW WILL SHOW "GROUND DETECTED!" BUT THIS DOES NOT MEAN THAT THE PARACHUTE WILL BE DISARMED. VERIFY THAT THE PSDK WINDOW DISPLAYS "DISARMED" BEFORE APPROACHING THE DRONE. {% endhint %}
