Maintenance
Cleaning
To maintain the keyboard's performance and appearance, regularly clean its surfaces. Use a soft, dry cloth to wipe down the keycaps and casing. For deeper cleaning, you may gently remove keycaps.
Keycap Removal and Switch Replacement
The provided keycap puller allows for easy removal of keycaps for cleaning or switch replacement. To remove a keycap:
- Gently place the keycap puller over the desired keycap, ensuring the prongs hook onto opposite sides of the keycap.
- Apply gentle, even pressure upwards until the keycap detaches from the switch stem.
To replace a switch (due to the hot-swappable design), use a switch puller (not included) to carefully extract the switch after keycap removal. Align the new switch with the pins and press firmly until it clicks into place.

Troubleshooting
If you encounter issues with your Jectse 12 Key Mechanical Gaming Keyboard, consider the following basic troubleshooting steps:
- No Response: Ensure the Type-C cable is securely connected to both the keyboard and your computer. Try a different USB port on your computer.
- Incorrect Key Output: Verify that your custom programming or macros are correctly configured. Re-program the affected key if necessary.
- RGB Lighting Issues: Cycle through the lighting modes to ensure it's not simply set to off or a very dim setting.
- Intermittent Connection: Try using a different Type-C cable to rule out cable defects.
For persistent issues, consult the manufacturer's support resources or contact customer service.
