6. Operation
6.1 Basic Functions
The GMK104 functions as a standard 104-key keyboard. Specific functions are often accessed via the 'Fn' key in combination with other keys (e.g., F-keys for multimedia, lighting control). Please note that the 'Fn' key cannot be locked.
6.2 Multi-functional Display Screen and Knob
The integrated display screen provides useful information at a glance. The multi-functional knob typically controls volume by rotating and media playback (play/pause) by pressing. Its functions can be further customized via VIA software.

6.3 RGB Backlighting
The keyboard features customizable RGB backlighting. Use the dedicated function keys (often Fn + arrow keys or specific F-keys) to cycle through lighting effects, adjust brightness, and change colors. Further customization is available through the VIA software.


7. Customization
7.1 Hot-Swapping Switches
The hot-swappable PCB allows you to change switches without soldering. Use a switch puller tool to carefully remove existing switches. Align the new switch's pins with the sockets and press firmly until it seats correctly. Ensure the keyboard is unplugged before performing this action.
7.2 VIA Programming
The GMK104 is VIA-programmable, offering extensive customization options:
- Key Remapping: Assign any key to a different function.
- Layer Configurations: Create multiple key layouts (layers) for different applications or preferences.
- Macro Creation: Record and assign complex sequences of keystrokes to a single key.
- RGB Customization: Fine-tune lighting effects, colors, and brightness beyond onboard controls.
Download the VIA software and the specific JSON file for the GMK104 from the provided links in the Setup Guide. The software provides an intuitive graphical interface for real-time adjustments.
8. Maintenance
8.1 Cleaning
- Keycaps: Use a keycap puller to remove keycaps. Clean them with mild soap and water, then dry thoroughly before reattaching.
- Keyboard Body: Use a soft, lint-free cloth dampened with a small amount of isopropyl alcohol to wipe down the case.
- Between Keys: Use compressed air to remove dust and debris from between the switches. A small brush can also be used.
8.2 Battery Care
- Avoid fully discharging the battery frequently.
- If storing the keyboard for an extended period, charge it to about 50% to prolong battery life.
- Do not expose the keyboard to extreme temperatures.

9. Troubleshooting
- Keyboard not responding: Check the connection cable (for wired mode) or ensure the 2.4GHz receiver/Bluetooth is properly paired and the keyboard is charged (for wireless modes). Try restarting your computer.
- Keys not registering: Ensure switches are fully seated in their sockets. If a specific switch is faulty, replace it using the hot-swap feature.
- RGB lights not working: Check lighting controls (Fn key combinations) or use VIA software to troubleshoot lighting settings. Ensure the keyboard is receiving sufficient power.
- Wireless connectivity issues: Ensure the keyboard is within range (10 meters for Bluetooth). Check for interference from other wireless devices. Re-pair the device if necessary.
- VIA software not detecting keyboard: Ensure the keyboard is connected via USB. Download and load the correct JSON file for the GMK104 in VIA.
10. User Tips
- Experiment with Switches: Take advantage of the hot-swappable PCB to try different switch types (linear, tactile, clicky) to find your preferred typing feel.
- Utilize VIA Layers: Create custom layers in VIA for different tasks, such as a gaming layer, a programming layer, or a multimedia control layer, to maximize efficiency.
- Regular Cleaning: A clean keyboard performs better and lasts longer. Make cleaning a routine part of your maintenance.
- Firmware Updates: Periodically check the ZUOYA website (http://www.zuoya.top) for any firmware updates that might improve performance or add new features.
