3. Close the battery compartment.

3.4 Pairing the Drone and Remote Control

1. Place the drone on a flat, level surface.
2. Power on the drone. The LED lights on the drone will flash.
3. Power on the remote control.
4. Push the left joystick (throttle) all the way up, then all the way down. The drone's LED lights will stop flashing and remain solid, indicating successful pairing.

3.5 Gyro Calibration

After pairing, it is recommended to calibrate the gyroscope for stable flight:

• With the drone on a flat surface and paired, press the calibration button on the remote control (refer to remote diagram for exact button).
• The drone's lights will flash rapidly and then become solid, indicating successful calibration.

4. Operating Instructions

4.1 Basic Controls

• Left Joystick (Throttle/Yaw): Push up/down to control altitude. Push left/right to rotate the drone (yaw).
• Right Joystick (Pitch/Roll): Push up/down to move forward/backward (pitch). Push left/right to move left/right (roll).

4.2 One-Key Take Off & Landing

After pairing and calibration, press the One-Key Take Off/Landing button (usually indicated by an arrow pointing up and down) on the remote control. The drone will automatically take off and hover at a certain altitude, or land gently.

4.3 Altitude Hold

The D9 Mini Drone features an altitude hold function, allowing it to maintain a stable height automatically when the throttle stick is released. This simplifies control and makes flying easier for beginners.

4.4 Headless Mode

In Headless Mode, the drone's orientation is relative to the pilot, regardless of which way the drone's front is facing. This is useful for beginners to avoid disorientation.

1. To activate, press the Headless Mode button on the remote control.
2. The drone's lights will flash to confirm activation.
3. To exit, press the Headless Mode button again.

4.5 Speed Adjustment

The drone has multiple speed modes (Low, Mid, High) to suit different skill levels and environments.

• Press the Speed Adjustment button (often indicated by a fan icon) on the remote control to cycle through the speed settings.
• The remote control may beep to indicate the current speed mode (e.g., one beep for low, two for mid, three for high).

4.6 3D Flips & Rolling

Perform exciting aerial stunts with the 3D Flip function.

1. Fly the drone to a height of at least 2 meters (6 feet).
2. Press the 3D Flip button on the remote control.
3. Immediately push the right joystick in any direction (forward, backward, left, or right) to execute a flip in that direction.

5. Maintenance

5.1 Cleaning

• Use a soft, dry cloth to clean the drone and remote control.
• Avoid using water or cleaning solvents, as they may damage electronic components.

5.2 Propeller Replacement

If a propeller is damaged, replace it with a spare propeller from the package.

1. Gently pull the damaged propeller straight up from the motor shaft.
2. Ensure the new propeller is correctly oriented (A or B, matching the existing propellers on the drone).
3. Press the new propeller firmly onto the motor shaft.

5.3 Battery Care

• Remove batteries from the drone and remote control when not in use for extended periods.
• Store batteries in a cool, dry place.
• Do not expose batteries to extreme temperatures.

6. Troubleshooting

• Drone does not respond to remote: Ensure both drone and remote are powered on and properly paired. Re-pair if necessary. Check remote control batteries.
• Drone flies erratically/unstable: Perform gyroscope calibration on a flat surface. Check for damaged propellers and replace if needed. Ensure no obstructions are interfering with propellers.
• Short flight time: Ensure batteries are fully charged. Flight time can be affected by aggressive flying or strong winds.
• Drone does not take off: Ensure batteries are fully charged and correctly installed. Check if propellers are spinning freely.
