6. Troubleshooting

- Check if the batteries are inserted correctly with the right polarity.
- Replace the batteries with fresh AAA batteries.
- Ensure the battery compartment cover is securely closed.
6.2. Light is Dim or Flickering

- The magnetic base is very strong; use it to attach the light to metal surfaces for hands-free operation during car repairs or in workshops.
- The red light mode is excellent for night vision preservation, making it ideal for stargazing or navigating in the dark without disturbing others.
- Consider carrying spare AAA batteries, especially for extended outdoor trips, as the lantern is battery-powered and not rechargeable.
