Powering On and Light Mode Selection
The Black Diamond Spot 400-R headlamp features a simple interface with two buttons. The main power button turns the light on and off.

To power on, simply press the power button once. Then, use the secondary button to select your desired light mode. Switching between modes is quick and intuitive, making it easy to adapt to various lighting conditions.

Brightness Adjustment
The Black Diamond Spot 400-R allows you to adjust the brightness of each light mode. To do this, press and hold the power button. The light will cycle through its brightness levels, from brightest to dimmest and back again.

This feature is incredibly useful for conserving battery life and adjusting the intensity of light according to your needs. The dimming functionality is smooth and precise, giving you excellent control over the illumination.

Instant Maximum Brightness
A small light icon on the side of the headlamp provides quick access to the brightest setting. Pressing this button instantly switches to maximum brightness, regardless of the current setting.

This is a convenient shortcut for situations requiring immediate, powerful illumination. The instant brightness function is invaluable for quickly reacting to changing conditions in the field or during emergencies.

Strobe and SOS Functions
The Black Diamond Spot 400-R also includes strobe and SOS functions. Double-tapping the power button activates the strobe, and the secondary button cycles through the available light modes for the strobe effect.

For the SOS function, switch to the red light mode and press the side button. The headlamp will then emit a repeating SOS signal. This feature is helpful in emergency situations.

Lock Function and Conclusion
To prevent accidental activation, you can lock the headlamp by holding both buttons for a few seconds. While the buttons offer good resistance, this lock feature provides an additional layer of security.
