Video: This video demonstrates the initial setup process, including app download, connection, and basic drone preparation for flight.
3.7 Calibrazione della bussola
Before the first flight, a mandatory compass calibration is required. Follow the on-screen prompts in the app:
- Push both the right and left joysticks simultaneously to the bottom right corner.
- Keep the drone parallel to the floor and rotate it about 3 times.
- Point the head of the drone upward and rotate it about 3 times.
- The transmitter will long beep once, indicating successful compass calibration.
3.8 Ricerca del segnale GPS
Place the drone on a flat surface after calibration. The drone will automatically search for GPS signals. The status LED will turn solid green once the search is finished (approximately 1 minute).
3.9 Calibrazione del giroscopio
Push the two joysticks to the bottom left corner to calibrate the gyro.
4. Utilizzo del drone
4.1 Decollo e atterraggio
- Sbloccare: Short press the unlock button on the remote controller.
- Decollare: Short press the takeoff button to initiate automatic takeoff.
- Landing: Short press the landing button to initiate automatic landing.
4.2 livelli di velocità
The drone offers two speed levels (High/Low). Push the speed button on the remote controller to switch between them.

- Scatta una foto: Short press the photo button on the remote controller or tap the camera icon in the app.
- Registra video: Long press the video button on the remote controller or tap the video icon in the app to start/stop recording.
- Impostazioni della fotocamera: Access camera settings in the app to choose between 2.5K and 4K resolutions.
- Ingrandisci: Use the zoom slider in the app to zoom in and out.
4.4 Modalità di volo intelligenti
The DEERC D65 offers several intelligent flight modes for enhanced creativity and ease of use:
- Seguimi: The drone will track your movement by following the GPS signal from your mobile phone. Ensure the drone's flight range is within 16-98 ft (5-30m).
- Orbit Flight: The drone will record its current position as the circle's center, then fly away from it to a set radius distance (default 15 ft / 5m) and begin to circle clockwise.
- Volo Waypoint: Tap the icon on the app interface, then tap a few points on the screen to create a flight path. Submit the path, and the drone will fly along the path created by connecting the points you tapped in order.
- Modalità senza testa: In Headless Mode, the pilot should stay facing the same direction that the drone's head points to when it takes off. This simplifies control by eliminating the need to orient the drone.
- Ritorno a casa (RTH): Tap the RTH button on the remote controller or in the app to activate. The drone will automatically fly back to its takeoff point. This function is also triggered if the signal drops or the battery runs low.

5. Manutenzione
- Pulizia: Utilizzare un panno morbido e asciutto per pulire il drone e il radiocomando. Evitare l'uso di solventi o prodotti chimici aggressivi.
- Sostituzione dell'elica: If propellers are damaged, replace them immediately using the provided screwdriver and spare propellers. Ensure correct propeller orientation (A and B types).
- Cura della batteria:
- Conservare le batterie in un luogo fresco e asciutto.
- Non sovraccaricare o scaricare eccessivamente le batterie.
- Se si conservano per periodi prolungati, caricare le batterie a circa il 50-60%.
- Magazzinaggio: Fold the drone arms and store all components in the carrying bag to protect them from dust and damage.
