{% hint style="danger" %}
DO NOT USE PROPELLER GUARDS WHEN USING THE PRS-M30, AS THIS WILL RESULT IN INTERFERENCE BETWEEN THE PRS-M30 AND THE PROPELLERS.
{% endhint %}

### 2. Pre-Flight Checklist <a href="#toc42537832" id="toc42537832"></a>

* [ ] Perform the DJI M30/T preflight checks.
* [ ] Verify and note any high-power RF emitters in the operational volume.
* [ ] Ensure the DJI M30/T is in the appropriate flight mode.
* [ ] Ensure the DJI M30/T is level and in the takeoff location.
* [ ] Turn on the PRS-M30 by powering on the DJI M30/T.

{% hint style="danger" %}
DO NOT HANDLE OR MOVE THE DJI M30/T ONCE THE PRS-M30 IS TURNED ON ON UNLESS CALIBRATING EITHER THE PRS-M30 IMU OR THE DJI M30/T COMPASS. REFER TO THE "[**CALIBRATION PROCESSES**](/prs-m30-for-dji-m30-and-m30t/prs-m30-for-dji-m30-series/calibration-processes.md)" SECTION FOR INSTRUCTIONS ON HOW TO CALIBRATE EACH OF THESE COMPONENTS..
{% endhint %}

* [ ] Ensure DJI M30/T downward-facing sensors are enabled.
* [ ] Arm the MTD (Toggle the ARM button).
* [ ] Takeoff and climb to minimum deployable altitude.

{% hint style="danger" %}
AUTO-TRIGGER WILL ONLY ARM ONCE AN ALTITUDE OF 36 METERS (118 FEET) IS REACHED. VERIFY THE ARM STATUS ON THE PSDK TEXT WINDOW \[ARMED: ATS].
{% endhint %}

{% hint style="danger" %}
MANUAL TRIGGER DEVICE CAN ONLY BE ARMED ONCE AN ALTITUDE OF 5 METRES (16.4 FT) IS REACHED.
{% endhint %}

### 3. In-Flight Checklist

{% hint style="danger" %}
THE MINIMUM FLYABLE ALTITUDE RATING FOR THE PRS-M30 IS 36.3 METERS. WHEN OPERATING OVER PEOPLE, DO NOT FLY BELOW THE 36.3 METERS (119.1 FEET). IF THE PRS IS DEPLOYED BELOW THE MFAR, AVSS DOES NOT WARRANT THE PRS WILL PERFORM AS INTENDED.
{% endhint %}

* [ ] Always fly in Normal Mode (N-Mode), Mission Mode, or Low-Speed Mode (T-Mode).&#x20;
* [ ] Fly in a safe and controlled manner.
* [ ] Avoid flying over people if unnecessary.
* [ ] Monitor the PRS status throughout the flight.

### 4. Landing Checklist <a href="#toc42537834" id="toc42537834"></a>

* [ ] Land the DJI M30/T gently on a level surface at a safe distance from people.
* [ ] The ATS should be temporarily disabled when the Drone is within five (5) meters (16 feet) of the ground and will be indicated by the "GROUND DETECTED!" message in the PSDK text window. The ATS should disarm approximately five (5) seconds after landing. The Drone Transmitter will indicate when the ATS disarms. Do not approach the Drone until the ATS is disarmed. If the ATS does not disarm ten (10) seconds after landing, then power off the drone without moving the drone and ensure the PRS is powered off.
* [ ] Check for the "DISARMED" message in the PSDK text window on the Drone Transmitter.
* [ ] Once the PRS-M30 is disarmed, turn off the DJI-M30/T.
* [ ] After the DJI-M30/T is off, the PRS-M30 will turn off after a few seconds.

{% hint style="danger" %}
ENSURE THE PRS-M30 LED IS OFF BEFORE HANDLING THE DJI M30/T.
{% endhint %}

### 5. Post-Flight Checklist (No Deployment) <a href="#toc42537835" id="toc42537835"></a>

* [ ] Turn off DJI M30/T and PRS-M30 BEFORE handling the DJI-M30/T.
* [ ] Inspect PRS-M30 and DJI M30/T for damage.

### 6. Deployment Checklist <a href="#toc42537836" id="toc42537836"></a>

* [ ] If necessary, the system can be deployed using the MTD.
* [ ] If possible, fly over a safe area free of people, cars, or obstacles.
* [ ] Press and hold the trigger button on the MTD.
* [ ] Visually follow the DJI M30/T’s descent to the ground.

### 7. Post-Flight Checklist (With Deployment) <a href="#toc39788550" id="toc39788550"></a>
