4. Setup
4.1 Initial Charging
Before first use, fully charge the headlamp. Connect the provided USB charging cable to the headlamp's charging port and to a standard USB power source (e.g., computer, wall adapter). An indicator light will typically show charging status (e.g., red for charging, green for fully charged).
4.2 Adjusting the Headband
Place the headlamp on your head and adjust the elastic strap to ensure a comfortable and secure fit. The strap should be snug enough to prevent movement during activity but not so tight as to cause discomfort.
5. Operating Instructions
5.1 Normal Mode Operation
Use the Power Button (usually marked with a power symbol) to cycle through the normal lighting modes:
- Press once: 3W XPE LED Hard Light (brightest, focused beam).
- Press twice: 3W XPE LED Weak Light (lower brightness, focused beam).
- Press three times: 3W XPE LED Flash Light (flashing mode).
- Press four times: Off.
Note: Some models may also include COB LED modes within the normal cycle. Refer to the specific button functionality on your device.
5.2 Motion Sensor Mode Operation
The motion sensor allows for hands-free control of the XPE LED light.
- Press the Motion Sensor Button (usually marked with a wave or hand symbol) to activate the motion sensor function. The XPE LED light will turn on in a specific mode (e.g., hard light).
- Once activated, wave your hand approximately 2-4 inches (5-10 cm) in front of the motion sensor to turn the XPE LED light on or off.
- To exit motion sensor mode, press the Motion Sensor Button again.

5.3 Adjusting the Light Angle
The headlamp unit can be tilted up or down to direct the light beam. Gently adjust the lamp head to your desired angle, up to 60 degrees.
