How do I perform a factory reset?

To perform a factory reset, you have two options.

Anduril (V1 & V2 — identical):

1. From Off mode, loosen the tailcap, then hold the button, and tighten the tailcap while still holding the button.
2. Continue holding the button for about 4 seconds.

Method 2: from Off mode, you can also perform a factory reset by:

1. Clicking 13H and keeping the button held for about 4 seconds.

If the tailcap method is not possible on your light, use the 13H method from Off mode.

Biscotti (12-Group): This feature does not exist in Biscotti firmware.
