5. Operating Instructions

5.1 Basic Numpad Functionality

The TH21 numpad functions as a standard numeric keypad. Press the NUM LOCK key to toggle between numeric input and navigation functions (e.g., Home, End, Page Up, Page Down) if applicable to your operating system.

5.2 RGB Backlight Control

The TH21 numpad features multiple RGB backlight effects. Specific key combinations are used to cycle through these effects and adjust their parameters:

• Change Effect: Refer to the quick start guide for the specific key combination (e.g., Fn + a designated key) to cycle through different lighting modes.
• Adjust Brightness: Use the designated key combination (e.g., Fn + Up/Down arrow) to increase or decrease backlight brightness.
• Adjust Speed: Use the designated key combination (e.g., Fn + Left/Right arrow) to change the speed of dynamic lighting effects.

5.3 Hot-Swapping Switches

The TH21 numpad supports hot-swappable switches, allowing you to change mechanical switches without soldering. This feature enables customization of typing feel and sound.

1. Remove Keycap: Use the provided keycap puller to gently remove the desired keycap. Grip the keycap firmly and pull straight up.
2. Remove Switch: Use the provided switch puller. Align the prongs of the switch puller with the two clips on the top and bottom of the switch. Squeeze the clips and gently pull the switch straight up and out of the PCB.
3. Install New Switch: Align the pins of the new 3-pin or 5-pin mechanical switch with the holes on the PCB. Ensure the switch is oriented correctly. Gently push the switch down until it clicks into place. Do not force the switch; if resistance is met, check pin alignment.
4. Replace Keycap: Place the keycap onto the new switch stem and press down firmly.

6. Maintenance

6.1 Cleaning the Numpad

To maintain the appearance and functionality of your TH21 numpad:

• Disconnect the numpad 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 casing.
• For dust and debris between keycaps, use compressed air or a small brush.
• Avoid using harsh chemicals or abrasive materials, as these can damage the surface.

6.2 Keycap and Switch Care

When removing or installing keycaps and switches, always use the provided tools and apply gentle, even pressure to prevent damage to the components or the PCB.

7. Troubleshooting

• Numpad Not Responding: Ensure the USB-C cable is securely connected to both the numpad and the computer. Try a different USB port or cable.
• Keys Not Registering: If individual keys are not working, ensure the switch is properly seated in the PCB. If the issue persists, try replacing the switch with a spare.
• RGB Backlight Not Working: Check if the backlight is turned off or set to minimum brightness using the designated key combinations. If the issue persists, try restarting your computer.
• Software Issues (Remapping/Macros): Ensure you have downloaded the correct and latest version of the EPOMAKER TH21 software from the official website. Run the software as an administrator. If problems persist, try reinstalling the software.
