2.1 Package Contents

Your ZUOYA GMK87 kit typically includes:

• GMK87 Keyboard Barebones Kit (case, PCB, plate, gaskets, etc.)
• USB Type-C Cable
• User Manual (this document)

Note: Switches and keycaps are not included in the barebones kit and must be purchased separately.

2.2 Installing Switches

The GMK87 features a hot-swappable PCB, allowing for easy installation and removal of 3-pin or 5-pin mechanical switches without soldering.

1. Align the pins of your desired mechanical switch with the holes on the PCB.
2. Gently push the switch down until it clicks into place. Ensure the switch is fully seated and the pins are not bent.
3. Repeat for all desired keys.

2.3 Installing Keycaps

Once switches are installed, place your keycaps onto the switches, ensuring they are firmly pressed down.

2.4 Initial Charging

The keyboard is equipped with a built-in 3000mAh lithium battery. For optimal performance, it is recommended to fully charge the keyboard before first use. Connect the keyboard to a USB power source using the provided Type-C cable.

3. Operating Instructions

3.1 Connectivity Modes

The ZUOYA GMK87 supports three connection methods:

• Type-C Wired: Connect the keyboard directly to your computer using the USB Type-C cable.

3.2 System Compatibility

The keyboard is fully compatible with both Windows and macOS environments. There is a physical switch located near the Type-C plug hole to toggle between system modes. Alternatively, you can use the key combination FN + A for macOS or FN + S for Windows to switch modes.

3.3 Multi-function Knob and TFT Screen

The GMK87 features an adjustable multi-function knob, typically used for volume control. The integrated TFT screen displays useful information such as time, battery status, and connection mode.

5. Maintenance

5.1 Cleaning

To clean your keyboard, disconnect it from your computer. Use a soft, dry cloth to wipe down the keycaps and case. For deeper cleaning, you may remove keycaps and use compressed air to clear debris from between switches. Avoid using harsh chemicals or abrasive materials.

5.2 Switch Replacement

Thanks to the hot-swappable PCB, switches can be easily replaced. Use a switch puller tool to carefully remove existing switches. Insert new switches by aligning the pins and pressing firmly until they click into place.

6. Troubleshooting

• FN Key Not Responding: The FN key is a function key and does not have a standalone response. It must be combined with other keys to activate its functions (e.g., FN + A for Mac mode). This is normal behavior and not a product issue.
• 'Menu' Key Not Opening in Testing Software: Similar to the FN key, some testing software may not register a response from the 'menu' key. This is not indicative of a product defect.
• Alt Key Showing Win Key Function (Windows System): If your computer is a Windows system and the Alt key behaves like the Win key, ensure the keyboard's system switch is set to Windows mode. This switch is located next to the Type-C plug hole. Alternatively, press FN + S to switch to Windows mode.
• Connectivity Issues: Ensure the keyboard is charged. For wireless connections, verify the 2.4GHz dongle is properly inserted or Bluetooth is paired correctly. Try switching between wired and wireless modes.
• FN Key Cannot Lock Function: The FN key on this keyboard is designed for momentary function activation and does not support a locking mechanism.

8. User Tips

• Always ensure the system switch (Mac/Windows) on the keyboard matches your computer's operating system for correct key functionality.
• When testing key functions with software, remember that the FN key is a modifier and will not register a single press.
• Take advantage of the VIA software to personalize your keyboard's layout, lighting, and macros to suit your workflow or gaming style.
• Regularly clean your keyboard to maintain its appearance and functionality, especially after hot-swapping switches.
