FAQ – Frequently Asked Questions
How does the battery indicator work?
The switch changes color depending on charge level: Green (100–50%), Orange (low), Red (very low), and flashing red indicating immediate charging is required.
What is the memory function?
The flashlight “remembers” the last brightness level used before turning off, so it returns directly to that mode when switched on again.
