5. Maintenance
5.1 Cleaning the Keyboard
To clean the transparent acrylic body and keycaps, use a soft, lint-free cloth. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner. Avoid harsh chemicals that may damage the acrylic.
5.2 Hot-Swappable Switches
The Phantom 68 features hot-swappable sockets, allowing you to easily replace mechanical switches without soldering. It is compatible with most 3-pin and 5-pin mechanical switches.
- Removing a Switch: Use the provided switch puller tool. Gently grip the switch from the top and bottom clips and pull upwards with even pressure until the switch detaches from the PCB.
- Installing a Switch: Align the pins of the new switch with the holes on the PCB. Ensure the switch is oriented correctly. Gently press the switch down until it clicks into place. Do not force the switch, as this may bend the pins. If resistance is met, remove the switch, check the pins for bending, straighten them if necessary, and reattempt installation.
