Connect Power: Connect the provided USB-C cable to the monitor light and then to a USB port on your PC or a smartphone charger. No extra power outlets or messy wiring are required.

Operating Instructions
The Quntis ScreenLinear Focus L205 offers various lighting modes and adjustments for optimal eye comfort.
Power On/Off
- Press the power button (usually indicated by a power icon) on the light bar to turn the light on or off.
Automatic Dimming Function
The monitor light features a built-in light sensor that detects ambient brightness and automatically adjusts the light's intensity to an optimal level.
- When the surrounding environment is bright, the light will automatically reduce its brightness.
- When the surrounding environment is dark, the light will automatically increase its brightness.

Manual Brightness Adjustment (Stepless Dimming)
You can manually adjust the brightness from 10% to 100% to suit your preference.
- Use the brightness control buttons (often +/- or a touch-sensitive area) on the light bar to increase or decrease the brightness.
Color Temperature Modes
The light offers three color temperature modes to match different activities and times of day:
- Daylight (6400K): Bright, cool light for enhanced focus during work.
- Natural White (4200K): Neutral light for comfortable long-term work.
- Warm White (3100K): Soft, warm light ideal for gaming or relaxation.
Press the color temperature button (often indicated by a sun or temperature icon) to cycle through these modes.
