3. Operating Instructions
3.1 Basic Key Functions
The Hz-61 is a 60% layout keyboard, meaning some functions are accessed via the FN key in combination with other keys. Refer to the diagram below for common combinations.

Figure 4: FN key combinations for various functions.
- FN + W/A/S/D: Toggles between standard arrow keys and WASD for gaming.
- FN + WIN: Locks/unlocks the Windows key to prevent accidental presses during gaming.
- FN + M: Adjusts lighting brightness.
- FN + ALT: Switches between different RGB lighting modes.
- FN + < / >: Adjusts lighting speed.
- FN + 1-12: Accesses F1-F12 functions.
3.2 RGB Lighting Control
The Hz-61 keyboard features customizable RGB backlighting. Use the FN key combinations mentioned above to cycle through 14 lighting effects, adjust 5 brightness levels, and set 5 different speeds.

The driver allows you to fine-tune actuation points and reset points for each key, providing a competitive edge in gaming. You can also create complex macros to streamline your workflow.
3.4 Magnetic Switch Technology
The Hz-61 utilizes Hall Effect magnetic switches, which detect key presses based on magnetic fields rather than physical contact. This design offers superior durability, faster response, and allows for features like Rapid Trigger, where key actuation and de-actuation can be customized based on travel distance.

The 8000 Hz polling rate ensures that every key press is registered almost instantaneously, providing a significant advantage in fast-paced applications and games.

4. Maintenance
4.1 Cleaning the Keyboard
The Hz-61 features a floating keycap design, which makes cleaning easier. To clean your keyboard:
- Disconnect the keyboard from your computer.
- Use a can of compressed air to blow away dust and debris from between the keycaps.
- Wipe the keycaps and keyboard surface with a soft, slightly damp cloth. Avoid excessive moisture.
- For deeper cleaning, you can remove the keycaps using the included keycap puller.

4.2 Hot-Swappable Switches and PBT Keycaps
The Hz-61 supports hot-swappable switches, allowing you to change switches without soldering. The included keycap and switch pullers facilitate this process.
- Use the keycap puller to gently remove the desired keycap.
- Once the keycap is removed, use the switch puller to carefully grip and pull out the switch.
- Align the pins of the new switch with the holes on the PCB and gently press it into place until it clicks.
- Replace the keycap.
