- Slide in the fully charged intelligent battery and push it into the battery slot.
- Close the battery hatch. Fasten the catch and then lock the hatch.
Low Battery
The SplashDrone 4 has two low battery warnings to help the pilot manage the drone’s battery life. Each time a battery level alarm is activated, the remote controller will beep and vibrate to alert the pilot.
Level 1 alarm: The drone battery level has reached 13.0 V. The remote controller screen will prompt “LOW BATTERY; Return Aircraft and Land”. The front drone status indicators will flash a pattern of 3 red lights. Please find a safe place to land the drone as soon as possible.
Level 2 alarm: The drone battery level has reached 12.0 V. The battery icon on the remote controller screen will flash. The battery level is now below 10%, and you should plan to land the drone safely. The remote controller screen will prompt “AIRCRAFT BATTERY LEVEL CRITICAL; Land Aircraft NOW”.
After 10 seconds, the drone will initiate an in-place auto-landing to protect the drone and battery. The front aircraft status indicators are going to flash red constantly.
To halt the Auto-Landing, switch the drone to ATTI mode to regain control of thedrone. If the pilot continues to fly the drone below 12 V (not recommended), there is a strong risk that the battery will not be able to maintain flight and the drone will fall out of the sky and crash (at the owner’s risk).
Aircraft Antenna
The antennas of the drone can be oriented either upwards or downwards to maximize reception in different situations. The SplashDrone 4 has an effective range of upto 3 km. Due to the way radio frequency travels, when flying 0.5m above the water, the transmission range can be reduced. For the drone floating on the water surface (with the drone antenna upwards), the transmission range reduces to 500m. Generally, upward-pointing antennas improve reception when the drone is floating or flying close to the water surface. Orienting the antennas downwards maximizes range for higher altitude flights. Adjust the antennas’ orientation to maximize range for your flight plan.
To adjust the antenna position: loosen the antenna nut, adjust the antenna position, and retighten the nut.
Strobe Light
The top of the aircraft is equipped with a high-intensity strobe light, which helps identify the drone’s position to the pilot and other air traffic. This meets the requirements of night flight regulations in some countries and helps ensure flight safety at night. The strobe can be activated and deactivated in the app (STB)
Water-Resistant Barometric Membrane
The water-resistant barometric membrane is SwellPro’s featured technology. It allows air to come through the internal body of the aircraft to keep the barometer functioning properly, while assisting in helping to resist water entry into the SplashDrone 4. The water-resistant barometric membrane is delicate yet an extremely important part for proper flying and water resistance. Therefore, you should pay special attention to the proper use of water resistant barometric membrane during your operation.
- Always check the water-resistant barometric membrane to ensure there is no damage before flying.
- Rinse the water-resistant barometric membrane thoroughly with freshwater after flying.
- Take out the top cover. Peel off the old water-resistant barometric membrane.
