Operation Guide
The flashlight features the advanced open-source user interface firmware, Anduril2. For full details of operation, please see the detailed manual: http://toykeeper.net/torches/fsm/anduril2/anduril-manual.txt
At the first glance of the UI , most fresh users will feel confused with the UI, But in fact , you can operate the light as easy as other common flashlights. Just in case you want to try more functions , you need to spend some time to read the manual . If you do not need the advanced features, just do not use it.
Anduril2 has two different operating user-interfaces.
1. Simple UI -- Stepped 5-mode ramping default (Easy to operate for all fresh users)
2. Advanced UI (need to spend some time to read the manual carefully to try more functions)
Enter advanced UI to unlock all the features available. It is simple to switch between Simple and Advanced UI.
