3. Key Features and Operation
3.1 Customizable OLED Display
The 1-inch OLED display on the MAXFIT81 provides real-time information and customization options. Users can display custom GIFs, PNGs, and artwork. It also shows essential keyboard status, PC information, time, and battery status.
3.2 Programmable Encoder Knob
Beyond standard volume control, the rotary encoder knob is fully programmable. It can be assigned various macros, including scrolling, changing songs, adjusting productivity settings, or even acting as a weapon wheel in games.
3.3 Hot-Swappable Switches
The MAXFIT81 features hot-swappable south-facing sockets, allowing users to easily change mechanical switches without soldering. This enables customization of typing feel and sound to personal preference.
3.4 Dense-Gasket & Foam Design
The keyboard incorporates a Dense-Gasket design and multiple layers of foam (plate foam, PCB dampener, case foam). This construction provides a stable and durable typing experience, reduces hollow sounds, and enhances overall usability by absorbing shock from keystrokes.
3.5 Personalization Software
For advanced customization, the MAXFIT81 FROST WIRELESS software allows for adjustable spectrum modes, button assignments, and easy-macro scripts. This software is available for download from the official Fantech website.
4. Maintenance
4.1 Cleaning
Regular cleaning helps maintain the keyboard's performance and appearance.
- Keycaps: Use a soft brush or compressed air to remove dust and debris between keycaps. For deeper cleaning, keycaps can be carefully removed using a keycap puller and washed with mild soap and water. Ensure they are completely dry before reattaching.
- Case: Wipe the keyboard case with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials.
4.2 Switch Replacement
Due to the hot-swappable design, switches can be replaced without soldering. Use a switch puller tool to gently remove the existing switch. Align the pins of the new switch with the sockets on the PCB and press down firmly until it clicks into place. Ensure pins are not bent during insertion.
