The rotary knob and display screen provide quick access to various settings:

• Rotary Knob: Typically controls volume (rotate) and media playback (press). Its functions can often be customized via VIA software.
• Display Screen: Shows real-time information such as connection mode (Wired, BT, 2.4G), battery level, time, and potentially other customizable indicators.

6. Maintenance

6.1 Cleaning

• Disconnect the keyboard from all power sources before cleaning.
• Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe the surface.
• For cleaning between keycaps, use compressed air or a small brush.

The GMK104 is equipped with a 4000mAh rechargeable lithium battery.

• Charge the keyboard using the provided USB-C cable connected to a computer or a compatible USB power adapter.
• Avoid fully discharging the battery frequently to prolong its lifespan.
• If storing the keyboard for an extended period, charge it to approximately 50% before storage.
• Do not expose the battery to extreme temperatures.

7. Troubleshooting

7.1 Keyboard Not Responding

• Wired: Ensure the USB-C cable is securely connected to both the keyboard and the computer. Try a different USB port or cable.
• 2.4GHz Wireless: Check if the dongle is properly inserted and the keyboard is switched to 2.4GHz mode. Ensure the keyboard battery is charged.
• Bluetooth: Verify the keyboard is in Bluetooth mode and successfully paired with your device. Re-pair if necessary. Ensure the keyboard battery is charged.
• Battery: Connect the keyboard via USB-C to charge it. A low battery can cause connectivity issues.

7.2 Backlight Not Working or Incorrect

• Check the keyboard's function key combinations for backlight control (e.g., brightness, mode).
• Ensure the keyboard is not in a low-power mode that disables backlighting.
• If using VIA software, verify that the lighting profile is correctly configured and applied.

7.3 Numpad Enter Key Issue

Some users have reported that the Numpad Enter key may function as 'Escape' by default, rendering the numpad enter key unusable. This is likely a software configuration issue.

• Connect the keyboard to your computer via USB-C.
• Open the VIA software.
• Navigate to the key remapping section and verify the assignment for the Numpad Enter key.
• Remap the key to its correct 'Enter' function if it is incorrectly assigned.
• If the issue persists after checking VIA, please contact customer support.

7.4 Setting the Clock on the Display Screen

The display screen can show the time. Setting the clock typically requires the use of the dedicated software (VIA) or specific function key combinations. Refer to the VIA software for clock synchronization options or check the ZUOYA website for specific firmware instructions.
