5. Operating Instructions
5.1 Using the GT4000S Jump Starter
- Ensure the jump starter is sufficiently charged (above 20%).
- Connect the jumper cable clamps to the jump starter unit.
- Attach the red clamp to the positive (+) terminal of the vehicle battery and the black clamp to the negative (-) terminal.
- Turn on the jump starter. The screen should display "READY" if the connection is correct and the battery is detectable.
- If the battery is completely dead or too low to detect, press the "BOOST" button for 1-2 seconds until "READY" is displayed. This forces the jump starter to provide maximum output.
- Start your vehicle's engine within 30 seconds.
- Once the vehicle starts, immediately remove the clamps from the car battery, then disconnect them from the jump starter.
