2. Clip: Connect the red (+) clamp to the positive terminal of your vehicle's battery and the black (-) clamp to the negative terminal. Ensure the clamps are firmly attached to the battery terminals.
3. Start: Once the clamps are correctly connected and the smart clamp LED indicator is green, start your vehicle's engine.
4. Off: After the vehicle starts, immediately remove the smart clamps from the car battery, then disconnect the smart clamps from the jump starter.

Important Safety Notes:

• Do not touch the red and black clamps together.
• Do not jump start a vehicle if the jump starter's battery level is too low.

Figure 7: Common Dead Vehicle Scenarios

• Device not turning on: Ensure the device is charged. If the battery is completely depleted, it may take a few minutes of charging before the indicator lights respond.
• Vehicle not starting:
  • Check if the jump starter has sufficient charge (at least 50%).
  • Ensure the smart clamps are securely connected to the correct battery terminals (red to positive, black to negative).
