Status Indications - Remote Controller
The PRS-M4DT status, also referenced as “Heartbeat” is indicated using a combination of LED colours. The PRS-M4DT status LED is located on the side of the PRS-M4DT facing the rear of the Drone. The LED colour on the PRS-M4DT indicates the stage of the flight.

MTD Interface and Info Screen:
PSDK Interface
The PSDK interface will show the AVSS PRS-M4DT user interface. This will allow access to the INFO screen for information on the PRS-M4DT, as well as the MTD function of the Drone transmitter. The Icon will appear white until the user clicks the icon. This will activate the PSDK window, and turn the icon yellow.
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 error messages window.
Status Messages
The status messages window will allow the user to consult the Drone transmitter for information on the PRS-M4DT 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-M4DT. 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-M4DT must first be armed through the configuration menu (see below) for the MTD to work.
Configuration
The configuration function, which is accessed through the three dots at the top of the Drone Transmitter's main screen, will allow the user to arm the PRS-M4DT (see below).
Arming/Disarming
THE PRS-M4DT MANUAL TRIGGER DEVICE CANNOT BE ARMED UNLESS A HEIGHT OF 34 METRES (111.5 FT) AGL IS REACHED.
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.
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.
