2. Wi-Fi network: DeercFPV-** Run the DEERC FPV app.
3. A successful connection is confirmed when the drone’s live video feed is displayed within the app interface.

• Connecting your phone to the drone’s Wi-Fi may take some time. Please remain patient and wait for the connection to be established successfully.
• For optimal connectivity, if you’re experiencing issues with the WIFI connection or the image transmission in the APP isn’t displaying, it’s advised to disable your phone’s Bluetooth, Mobile Data, and VPN. Alternatively, switch your phone to airplane mode and attempt to reconnect.

The Wi-Fi network created by the drone does not have internet access.

• As a result, your cellphone might:
• Notify you that the connection isn’t secure,
• Indicate theres no internet connection, or
• Suggest switching to cellular data. (The exact wording may vary based on cellphone models.)

Please disregard these messages. If prompted, select the option to remain connected to the current Wi-Fi.

Flight
Gyro-Calibration

Make sure to place the drone on a level surface before calibrating the gyro. Simultaneously push the left joystick and the right joystick to the bottom left corner to calibrate the gyro. The indicator lights on the drone will blink, then turn solid, which indicates that the calibration is completed.

To ensure a stable flight, we suggest that the pilot calibrates the gyro every time after pairing the drone and after a crash.

Flight
Unlocking the Motors

Simultaneously push the left joystick to the bottom right corner and the right joystick to the bottom left corner. The motors will rotate, and the drone is unlocked.

Flight Functions
Take Photo/Record Video

Take Photo: Short press the button on the transmitter to take a photo. The transmitter will beep once, signaling that a photo has been taken.
Record Video: Long press the button on the transmitter. The transmitter will long beep once, indicating that video recording has started. Press the same button again to stop recording.

Flight Functions

High-Speed Rotation

Short press the button , the drone will enter the High-Speed Rotation mode. Exit the High Speed Rotation mode by pressing the same button again or pushing the right joystick in any direction.

Flight Functions
Circle Fly

Long press the button , the drone will enter the circle Fly mode. Exit the Circle Fly mode by long pressing the same button again or pushing the right joystick in any direction.

Flight Functions
360° Flips

After you get familiar with all the functions of the drone, you can try this amazing flip mode. When the drone is at least 10 ft from the ground , press down on the (FLIP) button, then push the right joystick in any direction. The drone will perform a flip toward that direction

360°Flip functions better when the battery is fully charged.

Flight Functions
Speed Switch

This drone offers three speed modes: Low, Middle and High. By default, it’s set to Low speed.
To toggle between the modes , give the button a short press. The transmitter beeps once to indicate Low Speed, beeps twice to indicate Medium Speed and beeps three times to indicate High Speed.

Flight Functions
Headless Mode

The Headless Mode is a great training tool for beginner pilots. It is also useful when the drone is too far from the pilot (which makes it difficult to tell its orientation). It keeps the drone traveling forward, backward, left, or right when you move the right joystick in those directions, regardless of which way the front of the drone is pointed.

Flight Functions
Headless Mode

1. ACTIVATING: Long press the button to activate this mode. While in Headless Mode, the drone’s indicator lights will flash continuously, and the transmitter will keep beeping.
2. DEACTIVATING: Long press the button once more. A prolonged beep will sound, and the drone’s indicator lights will return to a steady glow, indicating the drone has successfully exited Headless Mode.

• Why is the orientation of the drone important?
  In normal flying mode, he control of the drone movement can sometimes be counter-intuitive for beginners. For instance, when the drone is in the air with its head pointing to your right, if you push the right joystick forward, the drone will fly to your right, instead of flying forward. With the headless mode, the drone has a fixed “head.”In Headless Mode, the drone always remembers the side its head points to during takeoff as the front side.
  This means that if the drone takes off with its head pointing forward, it doesn’t matter how the drone is oriented in the air, when you push the right joystick forward the drone will fly forward. Or, when its head is pointing to you, if you push the right joystick to the left, the drone will fly to your left.

Flight Functions
Emergency Stop

1. The Emergency Stop function should only be used in an emergency during the flight to avoid any damage or injury. Long Press the button. The transmitter will long beep once. The drone will fall down immediately.
   Be aware that you risk breakage of the drone if it falls from a large distance or hits anything at a high rate of speed.

2. After the drone hits the ground, The drone indicator will keep on flashing. Please out the drone on a level surface again, and push the left joystick downward. The drone indicator then turn from flashing to solid, which indicates that you can use the drone now.
   

Attitude Adjustment

Stabilization Functions
Altitude-Hold Function

The drone is designed with an altitude-hold function to maintain its altitude after releasing the left joystick. (The left joystick will automatically spring back to the middle)

Stabilization Functions
Optical Flow Positioning

The Optical Flow Positioning System consists of a camera module, which acquires the position information of the drone through visual images to ensure precise positioning of the drone. The optimal usage height for Optical Flow Mode is 1.6-9.8ft.

– The precision of the Optical Flow Positioning System is easily affected by the light intensity and features of the surface textures. Once the image sensor is not available, your drone will switch on the altitude-hold function automatically. Please exercise utmost caution when operating the drone under these circumstances:

Stabilization Functions

• Fly over surfaces without clear patterns or textures.
• Fly over extremely dark or bright surfaces.
• Fly in an area where the lighting changes dramatically and frequently.
• Fly over moving surfaces or objects. (e.g., above crowds, above bushes or grasses swayed by strong winds).
• Fly over water or transparent surfaces.
• Fly over highly light reflective surfaces. (e.g, mirrors)
• Fly over monochrome surfaces (e.g, pure black, red, or green).
• Flying over surfaces with repeating identical patterns or textures (e.g., tiles with the same design).
• Flying speed should be controlled not to be too fast.
  • Keep sensors clean at all times.
  • DO NOT scratch or tamper with the sensors. DO NOT use the aircraft in dusty or humid environments.
  • Make sure that the light is bright enough and the surface is with clear textures so that the Optical Flow Positioning can acquire the movement information through recognizing the ground textures.
