Precautions(HX ROV)

Read carefully before use. Failure to follow these precautions may result in personal injury, equipment damage, or loss. Users are liable for any consequences of improper operation.

1. Unauthorized Opening: Opening the electronic compartment voids the warranty.
2. Battery Polarity: Reversing battery poles will burn out the machine.
3. Charging Wiring: Incorrectly connecting the battery's signal feedback wire during charging will damage the battery.
4. Cable Integrity: Using a damaged cable underwater causes leakage and risk of cable breakage and equipment loss.
5. Surface Damage: Operating with a corroded or damaged equipment surface risks water leakage.
6. Motor & Lights: Do not use the motor and underwater lights in air for over 30 seconds to prevent burnout.
7. Control Modes Restrictions: Depth Hold, Stabilize, and trajectory control are not for air use; may burn out the motor. Always set to manual before ROV recovery.
8. Battery Voltage: 4s battery: 12V - 16.8V; 6s battery: 18V - 25.2V. Recover the ROV once the voltage comes close to the minimum reading; under - voltage operation may over - discharge the battery.
9. Battery Handling: Do not squeeze, drop, immerse, or expose batteries to open flames. Avoid extreme temperatures to prevent damage, fire, or explosion.
10. Battery Removal: Remove the battery promptly after robot recovery to prevent overdischarge and recharge failure.
11. Battery Current: 4s battery max current: 30A; 6s battery: 45A. Exceeding may cause explosion.
12. Propeller Obstructions: Hair, plants, or debris stuck in the propeller can stall the motor, burn it out, or damage the battery.
13. Flow Rate: Currents over 4 knots may overload and burn out the battery or motor, leading to equipment loss.
14. Environmental Hazards: Using in extreme temperatures, interference, radiation, or corrosive liquids can degrade performance, cause leakage, image loss, or communication failure.
15. Turbid Waters: Light scattering in turbid waters may obstruct the view ahead.
