4.2. Actuation Point Changer (APC)

The APC function allows you to adjust the actuation point depth for each key individually. This means you can set how far a key needs to be pressed before it registers a keystroke. Available settings are 0.8mm, 1.5mm, 2.2mm, or 3.0mm.

• Open the Realforce software.
• Navigate to the APC settings section.
• Select the desired actuation point for individual keys or apply a setting globally.
• Save your changes to the keyboard's on-board memory.

4.3. Heat Map Function

The heat map feature in the Realforce software visually displays which keys you use most frequently. This can help you identify keys for which you might want to adjust the APC setting or reassign functions.

4.4. Custom Keymap Function

Customize key assignments to suit your workflow. You can remap individual keys to perform different functions or macros using the Realforce software.

4.5. Key Layout Switching Function

Switch between two predefined key layouts (Layout A or Layout B) on the fly. This is useful for adapting to different applications or operating systems (e.g., Windows and macOS layouts).

4.6. ECO Mode Setting

Adjust the battery consumption settings when using Bluetooth to optimize battery life. This can be configured through the Realforce software.

5. Maintenance

To ensure the longevity and optimal performance of your Realforce R3 TKL keyboard, follow these maintenance guidelines:

• Cleaning: Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe the keycaps and keyboard surface. Avoid harsh chemicals or abrasive materials.
• Dust Removal: Use compressed air to remove dust and debris from between the keycaps.
• Liquid Spills: In case of a liquid spill, immediately disconnect the keyboard from your computer (both USB and remove batteries). Turn the keyboard upside down to drain liquid and allow it to dry completely for at least 24-48 hours before reconnecting. Do not use a hairdryer as excessive heat can damage components.
• Storage: Store the keyboard in a dry, cool environment away from direct sunlight and extreme temperatures.
