Maintenance
Cleaning
Regular cleaning helps maintain the keyboard's performance and appearance:
- Disconnect the keyboard from your computer before cleaning.
- Use a soft, dry, lint-free cloth to wipe the keycaps and chassis.
- For deeper cleaning, use the provided keycap puller to carefully remove keycaps. This allows access to the switches and plate for cleaning with compressed air or a small brush.
- Do not use harsh chemicals or abrasive materials, as these may damage the keyboard's finish or keycap legends.
Hot-Swappable Switches
The NB981 features a hot-swappable PCB, allowing you to replace 3-pin or 5-pin MX-style mechanical switches without soldering. This is useful for customization or replacing faulty switches.
- Using the provided switch puller, carefully grip the top and bottom tabs of the switch you wish to remove.
- Gently pull the switch upwards until it detaches from the PCB.
- Take the new switch and ensure its pins are straight. Align the pins with the corresponding holes on the PCB.
- Gently press the new switch into place until it clicks. Ensure it is fully seated and the pins are not bent during insertion.
- Test the new switch to confirm proper function.
