Operating Instructions
General Usage
The Gi80 keyboard functions as a standard QWERTY keyboard. Its 75% layout includes all essential keys, with the directional keys separated for ease of access during gaming or general use.
Keycap Design and Ergonomics
The patented MDA keycaps are designed with both upper and lower curvature, differing from traditional ergonomic keycaps. This design promotes faster finger movement and reduces strain during extended use. The high-content PBT material ensures durability, while the thermal sublimation process provides a smooth, long-lasting finish.

Maintenance
Cleaning
- Disconnect the keyboard 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 keyboard surface.
- For dust and debris between keys, use compressed air.
- Avoid using harsh chemicals or abrasive materials, as these can damage the keyboard's finish.
Water Resistance
The Gi80 keyboard is designed with water resistance. While it can withstand minor spills, it is not fully waterproof. Avoid submerging the keyboard in liquid. In case of a spill, immediately disconnect the keyboard, wipe it dry, and allow it to air dry completely before reconnecting.
