Power On/Off and Brightness Adjustment
- To Turn On/Off: Press the large power button once.
- Brightness Memory: The headlamp features a memory mode that stores your last used brightness setting. When you turn the light back on, it will resume at that saved brightness level.
- PowerTap Technology: To quickly switch between full power and dimmed light, simply tap the side of the headlamp housing. This allows for rapid brightness adjustments without cycling through modes.
- Dimmable Feature: While the light is on, press and hold the large power button to dim the light. Release the button when the desired brightness is reached.
Lighting Modes
The Spot 400 offers several lighting modes for various situations:
- High Beam: Provides maximum illumination for long-distance visibility.
- Close Range: A wider, less intense beam suitable for proximity lighting.
- Flashing Mode: For signaling or increased visibility.
- Night Vision Mode (Red): Activates a red light for preserving night vision. This mode can be activated directly without cycling through normal white light modes. It also has dimming and flashing settings.

Maintenance
Cleaning
Wipe the headlamp body with a damp cloth as needed. Do not use harsh chemicals or abrasive cleaners. Ensure the lens is clean for optimal light output.
Battery Care
