Operating Instructions
General Jump Starting Procedure
Ensure the jump starter is fully charged before attempting to jump start a vehicle. Always follow the connection order to ensure safety.
- Connect the smart jumper cable's blue plug into the jump start socket on the VTOMAN V10 Pro.
- Connect the red (+) clamp to the positive (+) terminal of the vehicle's battery.
- Connect the black (-) clamp to the negative (-) terminal of the vehicle's battery.
- Observe the indicator light on the smart jumper cable.
- Start the vehicle's engine.
- Once the vehicle starts, immediately disconnect the black (-) clamp first, then the red (+) clamp from the battery.
- Disconnect the smart jumper cable from the jump starter.

Boost Mode (for totally dead batteries)
If the vehicle's battery is completely dead (voltage too low to detect), the smart jumper cable may not show a green light. In this case, use the 'BOOST' function:
- Follow steps 1-3 of the General Jump Starting Procedure.
- Press and hold the 'BOOST' button on the smart jumper cable for 3-5 seconds until the green light flashes. This indicates the boost function is active.
- Start the vehicle's engine within 30 seconds.
- Immediately disconnect the black (-) clamp first, then the red (+) clamp from the battery.
- Disconnect the smart jumper cable from the jump starter.

Troubleshooting
If you encounter issues with your VTOMAN V10 Pro Jump Starter, refer to the following common scenarios:
| Problem | Possible Cause | Solution |
|---|---|---|
| Jump starter does not turn on. | Battery is completely discharged. | Recharge the jump starter fully. |
| Smart clamp indicator shows red light (Reverse Polarity). | Clamps are connected to the wrong battery terminals. | Disconnect clamps and reconnect red to positive (+), black to negative (-). |
| Smart clamp indicator flashes green (Low Battery). | Vehicle battery is extremely low or totally dead. | Use the 'BOOST' function as described in the Operating Instructions. |
| Vehicle does not start after jump attempt. | Vehicle battery is severely damaged or other vehicle issues. | Consult a professional mechanic. The jump starter may not resolve all battery-related issues. |
| Jump starter gets hot during use. | Normal operation under heavy load or prolonged use. | Allow the device to cool down. The built-in high-temp protection will prevent overheating. |
