6. Operating Instructions
6.1. Jump Starting a Vehicle
Ensure the jump starter is at least 20% charged before attempting to jump-start a vehicle.
- Connect Clamps: Plug the smart jumper clamps into the EC5 output port of the jump starter. Ensure a secure connection.
- Attach to Battery: 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.
- Check Display: The jump starter's display should show 'READY' if the connection is correct and the battery voltage is detected. If a fault is detected, the 'Fault Detection Indicator' will illuminate.
- Start Vehicle: Start your vehicle's engine. If the vehicle does not start immediately, wait 30 seconds before trying again. Do not crank the engine for more than 3 seconds per attempt.
- Remove Clamps: Once the vehicle starts, immediately remove the smart clamps from the vehicle battery, then disconnect them from the jump starter.

Force Start Mode:
If your vehicle's battery is completely dead (0V) and the jump starter does not display 'READY', you may need to use Force Start Mode.
- Connect the smart clamps to the jump starter and then to the vehicle battery terminals as described above.
- Press and hold the 'Force-Start Button' on the jump starter for 3 seconds. The 'Force Start Indicator' will illuminate.
- Start your vehicle's engine within 30 seconds.
- Once the vehicle starts, immediately remove the smart clamps.
CAUTION: Use Force Start Mode only when necessary, as it bypasses some safety checks. Ensure correct polarity before activating.
