Troubleshooting Guide
Refer to the indicator light troubleshooting guide on the smart clamp for common issues:
- Red light is always on: Check if the clamps are reversed (red to negative, black to positive). Reconnect correctly.
- The red light is always on, and the buzzer beeps quickly: Check whether the clips are connected together or if the same metal conductor is always touching. Remove the clip from the car battery and reconnect it.
- The red light is always on, and the buzzer beeps slowly: The car battery is severely discharged. Press the BOOST button for 3 seconds, wait for the green light to turn solid, and start the vehicle within 30 seconds.
- No light is on: The car battery may be completely dead. Press the BOOST button for 3 seconds, wait for the green light to turn solid, and start the vehicle within 30 seconds.
