3. The display screen will show the charging progress. A full charge is indicated when the battery icon reaches 100%.

It is recommended to fully charge the jump starter before first use and to maintain a charge level above 80% for optimal performance. Avoid charging immediately after jump-starting a vehicle; allow the unit to cool down for at least 30 minutes.

4. Operating Instructions: Jump Starting a Vehicle

Follow these steps to safely jump-start your 12V vehicle:

1. Ensure the jump starter is sufficiently charged (above 80% is recommended).
2. Insert the smart jumper cable plug completely into the jumpstart port on the UTRAI JS5 unit.
3. Connect the red (+) clamp to the positive terminal of your vehicle's battery.
4. Connect the black (-) clamp to the negative terminal of your vehicle's battery.
5. Check the indicator light on the smart clamp. A solid green light indicates a correct connection and readiness to start. If red lights flash or a beeping sound occurs, refer to the troubleshooting section.
6. Start your vehicle's engine.
7. Once the vehicle starts, immediately remove the jumper cable from the jump starter, then disconnect the black (-) clamp, followed by the red (+) clamp from the vehicle battery within 30 seconds.

Force Start Function (for extremely dead batteries):

If the vehicle fails to start after 3 attempts with correct connection, you can use the force start function:

1. Press and hold the forced start button on the smart clamp for approximately 3 seconds.
2. The current voltage value will be shown on the display. Release the button to enter the energized state.
3. Start the engine.
4. Pressing the button again briefly terminates the energized state.

Note: The force start function bypasses some safety checks. Use with caution and only when necessary.
