Operating Instructions
1. Rapid Trigger (RT) and Dynamic Keystrokes (DKS)
The K85 keyboard features magnetic switches that allow for highly customizable actuation points and rapid trigger functionality. These features are primarily configured through the dedicated software.
- Adjustable Actuation Point: Customize the keystroke actuation point from a light 0.2mm to a strong 3.8mm. This allows you to fine-tune the sensitivity of each key to your preference.
- Rapid Trigger (RT): This function enables keys to reset and re-press faster than traditional mechanical switches. It allows for instant re-actuation upon key lift, providing a significant advantage in fast-paced games.
- Dynamic Keystrokes (DKS): Bind up to 4 functions to a single key based on different pressing depths. For example, a light press could activate one action, while a deeper press activates another.

The K85 keyboard features a full-key hot-swappable PCB base, allowing you to easily change switches without soldering. Please note that it is currently only compatible with Outemu magnetic switches.
Important: After replacing any Outemu magnetic switch, recalibration in the software is necessary. Navigate to the "About" section in the software, then "Maximum stroke calibration," and press "Start Calibration" by gently pressing every key.

Proper maintenance ensures the longevity and performance of your keyboard.
- Cleaning Keycaps: Use the provided keycap puller to carefully remove keycaps. Clean them with a soft, damp cloth and mild soap if necessary. Ensure they are completely dry before reattaching.
- Cleaning Switches: Use compressed air to remove dust and debris from around the switches. Avoid spraying liquids directly into the switches.
- General Cleaning: Wipe the keyboard surface with a soft, dry cloth. Avoid abrasive cleaners or solvents.
Troubleshooting
If you encounter issues with your ATTACK SHARK K85 keyboard, refer to the following common solutions:
