4. Setup

4.1 Drone Assembly

1. Unfold the Drone Arms: Gently unfold the four rotor arms until they lock into position. Ensure all arms are fully extended and secure.

4.2 Battery Installation and Charging

1. Drone Battery: Insert the 3.7V 2000mAh intelligent flight battery into the battery compartment on the drone. Ensure it clicks securely into place.
2. Remote Control Batteries: Open the battery cover on the back of the remote control and insert 3 AA batteries (not included), observing correct polarity. Close the cover.
3. Charging: Connect the drone battery to the USB charging cable, then plug the cable into a 5V USB power source. The charging time is approximately 1 hour. The indicator light will show charging status (refer to the manual for specific light patterns).

5. Operating Instructions

5.1 Remote Control and App Connection

1. Power On: Turn on the drone first, then the remote control.
2. Pairing: The drone and remote control should automatically pair. If not, follow the pairing sequence in the quick start guide (usually pushing the left joystick up then down).
3. App Installation: Download the dedicated drone control app to your mobile phone (refer to the manual for the specific app name and QR code).
4. Wi-Fi Connection: Connect your mobile phone to the drone's Wi-Fi network (usually named 'S2S-XXXXXX'). This enables FPV (First Person View) and app control. The image transmission distance is approximately 50 meters.

5.2 Flight Preparation

1. Calibration: Perform gyroscope calibration before the first flight and after any hard landing. Place the drone on a flat surface and follow the calibration procedure outlined in the quick start guide (typically a specific joystick combination).
2. GPS Signal (if applicable): For outdoor flights, wait for a sufficient GPS signal lock before taking off to ensure stable positioning.

5.3 Basic Flight Operations

• Take-off/Landing: Use the one-button take-off/landing function on the remote control or app.
• Altitude Hold Mode: The drone maintains a stable altitude automatically, making it easier to control.
• Optical Flow Positioning: Provides stable hovering, especially useful for indoor flight or when GPS signal is weak.
• Headless Mode: In this mode, the drone's orientation is relative to the pilot, simplifying control regardless of the drone's front direction.
• Obstacle Avoidance: The drone features 360-degree, four-way laser obstacle avoidance, allowing it to detect and stop before colliding with obstacles.

5.4 Advanced Flight Functions

• Gesture Photography/Video: Perform specific hand gestures within 1-5 meters of the drone to trigger photo or video recording.
• Custom Route Flight: Draw a desired flight path on the app interface, and the drone will automatically follow it.
• One-Button Return: Press the return button, and the drone will automatically fly back to its take-off point.

5.5 Camera Operation

The S2S drone is equipped with a dual camera system:

• Front Camera: 4K/8K HD wide-angle lens with electronic anti-shake (EIS) for clearer images. The camera angle can be adjusted by the transmitter up to 90 degrees.
• Bottom Camera: High-definition optical flow lens.
• Photo Resolution: Up to 33 MP effective still image resolution.
• Video Resolution: Supports 4K and 8K video capture at 25 frames per second (fps).
• Storage: Insert a Micro SD, Micro SDHC, or SDXC card (not included) into the drone's card slot to save photos and videos.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your drone:

• Cleaning: Use a soft, dry cloth to clean the drone body and camera lenses. Avoid using liquids or solvents.
• Propeller Inspection: Regularly check propellers for cracks, bends, or damage. Replace any damaged propellers immediately using the provided spare parts.
• Battery Care: Store batteries in a cool, dry place. Do not store fully charged or completely depleted batteries for extended periods. Charge them to about 50-60% for long-term storage.
• Motor Inspection: Ensure the brushless motors are free from debris and spin smoothly.
• Storage: When not in use, store the drone in its protective bag in a dry environment.
