Maintenance
Cleaning
The lantern is made from durable, recyclable PET material. To clean, gently wipe the surface with a damp cloth. Avoid using harsh chemicals or abrasive cleaners, which may damage the material or solar panel.

Troubleshooting
- Lantern not lighting up: Ensure the solar panel has received adequate direct sunlight for charging (10-12 hours). Check that the power button has been pressed correctly to activate a light mode.
- Short battery life: Verify that the lantern is receiving full, unobstructed direct sunlight during charging. Partial shade or cloudy conditions can reduce charging efficiency and battery life.
- Difficulty unfolding or collapsing: The PET material has a memory for its shape. Gently manipulate the lantern to unfold or collapse. Avoid excessive force.
