# Safety Instructions

{% hint style="danger" %}
**BEFORE MOVING THE DRONE BY HAND, POWER OFF THE DRONE AND ENSURE THE PRS IS OFF. FAILURE TO POWER OFF THE DRONE BEFORE DISPLACING IT BY HAND MAY INCREASE THE CHANCE OF INADVERTENT ACTIVATION OF THE PRS. SEE THE "**[**CALIBRATION PROCESSES**](https://avss.gitbook.io/prs-m3dt-for-dji-dock2/prs-m3dt-for-dji-m3d-and-m3td/calibration-processes)**" SECTION FOR INSTRUCTIONS ON DRONE COMPASS CALIBRATION AND PRS IMU CALIBRATION.**

<table data-header-hidden><thead><tr><th width="219"></th><th></th></tr></thead><tbody><tr><td>Eye Protection</td><td>As with any system designed to launch a mass at high velocity, precautions shall be taken to prevent potential injury. Users should wear eye protection.</td></tr><tr><td>Never point the Parachute Pod™ towards anyone or anything</td><td>While the PRS-M3DT includes features to prevent unintentional deployments, users shall be aware that the Parachute Pod™ is launched vertically. The operator must maintain a clear area of at least five (5) meters (16 feet) after the system has been powered.</td></tr><tr><td>Disarming MTD</td><td>Verify that the PSDK text window displays the "DISARMED" message before approaching the drone. Then hide the PSDK menu to avoid inadvertently pressing the MTD button before approaching the Drone after a landing or in the event of an aborted takeoff.</td></tr><tr><td>Ensure PRS-M3DT is OFF before moving it</td><td>Do not pick up the PRS-M3DT when it is powered on and connected to the drone as the sensors may interpret the movements as an in-flight failure. Power off the drone and PRS before moving the drone. See the "<a href="calibration-processes">Calibration Processes</a>" section for instructions on handling the drone for calibration.</td></tr><tr><td>Error Status</td><td>The system shall not be used if errors are present. The system will not arm itself or deploy in a failure scenario unless it has initialized successfully and no errors are present.</td></tr><tr><td>Parachute Repacking</td><td>Only parachutes packed by AVSS are compliant. The Parachute shall be repacked or replaced every twelve (12) months only by AVSS.  You will no longer be compliant and will void the warranty if you attempt to repack the Parachute.</td></tr><tr><td>Flight Mode Changes</td><td><p>The ATS is designed to automatically detect abnormal flight behaviors. Flying in a controlled manner and avoiding erratic maneuvers ensures that the PRS-M3DT can more accurately distinguish between pilot commands and loss of control. It is not recommended to change the flight mode mid-flight, as the drone may execute an abrupt maneuver that can exceed the maximum allowable "25°-degree pitch angle”, as per the manufacturer.</p><p> </p></td></tr><tr><td>Rules and Regulations</td><td>Pilots shall follow the rules and regulations put in place by civil aviation or government bodies in their operating regions.</td></tr><tr><td>Energetic Charge Warning</td><td>The PRS-M3DT utilizes an automotive pyrotechnic as the means of deployment. These charges are similar to that in automobile airbag and seat belt systems. Caution should always be observed around the system. Ensure the System is never pointing towards someone. Note, throughout this document, the pyrotechnic charge is referenced as an "Energetic Charge".</td></tr></tbody></table>
