4. Setup Guide

4.1 Connecting the Keyboard

1. Locate the USB-C port on the keyboard and the USB-A port on your computer.
2. Connect the provided USB-C to USB-A cable to both the keyboard and your computer.
3. The keyboard will be automatically recognized by your operating system.

4.2 Driver Installation and Initial Calibration

For full functionality and customization, it is recommended to install the Redragon driver. The K721 magnetic switch keyboard requires calibration before first use to ensure accurate actuation point detection.

1. Download the latest client driver from redragon.com or access the web driver at illumipc.com.
2. Install the client driver following the on-screen instructions, or open the web driver in your browser.
3. Within the driver software, navigate to the "Calibration" section.
4. Initiate the "All-key Calibration" process. The software will guide you to press each key on the keyboard.
5. Press each key firmly to its bottom-out point as prompted. The software will indicate successful calibration for each key.
6. Once all keys are calibrated, save the settings and exit the calibration mode.

5. Operating Your Keyboard

5.1 Adjusting Actuation Points

The magnetic switches allow you to customize the actuation point for each key. This is done through the Redragon driver software. A lower actuation point (e.g., 0.1mm) results in a faster response, ideal for gaming, while a higher point (e.g., 4mm) can prevent accidental presses, suitable for typing.

1. Open the Redragon driver software.
2. Navigate to the "Actuation" or "Magnetic Switch Settings" section.
3. Select the desired key(s) or apply a global setting.
4. Adjust the actuation depth using the provided slider or input field (from 0.1mm to 4mm).
5. Save your changes.

5.2 Utilizing Rapid Trigger

Rapid Trigger mode dynamically actuates and resets keys based on your intent to press and release. This feature is particularly beneficial for competitive gaming, allowing for extremely fast repeated inputs.

1. Access the Redragon driver software.
2. Locate the "Rapid Trigger" setting.
3. Enable or disable Rapid Trigger as needed.
4. Some drivers may allow fine-tuning of Rapid Trigger sensitivity. Adjust according to your preference.
5. Apply settings.

5.3 Understanding 8KHz Polling Rate

The 8KHz polling rate means the keyboard reports its status to your computer 8000 times per second, significantly reducing input latency to 0.125ms. This is an automatic feature of the K721 and does not require manual configuration.

5.4 Volume Knob Functionality

The dedicated volume knob located on the top right of the keyboard provides quick and intuitive audio control:

• Rotate clockwise to increase volume.
• Rotate counter-clockwise to decrease volume.
• Press the knob to mute/unmute audio.

5.5 Customizing RGB Backlighting

The keyboard features 16.8 million color RGB backlighting with various effects. Customization is primarily done through the driver software:

1. Open the Redragon driver software.
2. Navigate to the "Lighting" or "RGB Settings" section.
3. Choose from preset lighting modes, or create your own custom effects.
4. Adjust brightness, speed, and color palette.
5. Apply your desired lighting profile.

5.6 Advanced Software Features (Macros, Key Remapping)

The Redragon driver software allows for advanced customization:

• Key Remapping: Assign new functions to individual keys.
• Macro Recording: Create complex sequences of keystrokes and assign them to a single key for quick execution.
• Refer to the driver software's built-in help or the Redragon website for detailed instructions on these advanced features.

6. Maintenance

6.1 Cleaning

• Disconnect the keyboard from your computer before cleaning.
• Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe the keycaps and chassis.
• For dust and debris between keys, use compressed air.
• Avoid spraying liquids directly onto the keyboard.

6.2 Switch Care

The magnetic switches are designed for durability. If you need to remove keycaps for deeper cleaning or replacement, use the provided keycap puller to avoid damaging the keycaps or switches. Do not attempt to disassemble the switches unless you are familiar with the process, as this may void your warranty.
