Operating Instructions
1. RGB Backlighting Control
The DK440R features customizable RGB backlighting with 19 different lighting modes. These modes can be cycled through and adjusted directly on the keyboard or via dedicated software (if available from DELTACO GAMING).
- Changing Modes: Use the Fn key in combination with specific keys (e.g., Fn + \ | or Fn + Right Ctrl) to cycle through the 19 pre-set RGB lighting effects.
- Adjusting Brightness: Typically, Fn + Up Arrow increases brightness, and Fn + Down Arrow decreases brightness.
- Adjusting Speed: Fn + Left Arrow or Fn + Right Arrow may adjust the speed of dynamic lighting effects.
- Color Selection: Some modes allow for static color selection using Fn + specific keys (consult the keyboard's keycap legends for exact combinations).

3. Battery Status Indication
The keyboard may have an LED indicator to show battery status. Refer to the keyboard's specific LED behavior for low battery warnings or charging status.

- Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe the keycaps and chassis.
