Mode Selection and Operation:
To select a mode, hold the flashlight horizontally and rotate your wrist to cycle through the available modes indicated around the tail cap. Once the desired mode is aligned, press the tail cap button to activate it.
For modes with variable settings (e.g., brightness in Normal Mode, strobe rate in Strobe Mode), rotate the flashlight while the mode is active to adjust the intensity or rate. The flashlight will remember your last setting for each mode.
