Operating Instructions
Mode Selection (Toggle Switch)
The toggle switch on the side of the flashlight allows you to select between different lighting modes:
- Lock Mode: Prevents accidental activation. Ensure the switch is in this position when not in use.
- Side Light Mode: Activates the side LED panel for area illumination.
- Main Light Mode: Activates the primary front LED for focused beam illumination.
- Moonlight Mode: Provides a very low light output, ideal for preserving night vision or discreet use. This position also exposes the USB-C charging port.

RGB Light Modes (Side Light)
In Side Light Mode, press and hold the rotary switch to cycle through different RGB colors. Rotate the switch to fine-tune the color or select specific flashing patterns (e.g., red-blue flash for emergencies).
