3. Features Overview
3.1 Hall Effect Magnetic Switches
The YK61 utilizes Hall Effect magnetic switches, which detect key presses using magnetic fields instead of physical contact. This design eliminates wear and tear, providing precise and consistent actuation. Key travel is 4.0 ± 0.3mm, with an actuation force of 35 ± 5gf and a durability of approximately 100 million presses.

3.2 Rapid Trigger Mode
Rapid Trigger mode allows for dynamic actuation and deactuation based on key movement, enabling faster repeated inputs. This feature is particularly beneficial for competitive gaming, allowing for quicker peeking and shooting in FPS titles.

3.3 Ultra-High Speed Response
The YK61 boasts an 8000Hz polling rate, delivering data to your computer 8 times faster than standard 1000Hz devices. This results in an ultra-low input latency of 0.125ms, providing a significant advantage in fast-paced games.

5. Operating Instructions
5.1 Basic Key Functions (60% Layout)
The YK61 features a 60% layout, meaning some standard keys (like function keys, arrow keys, and numeric keypad) are accessed via a combination of keys, typically using the Fn key.
Refer to the quick reference card included in the box for specific Fn key combinations. Common combinations include:
- Fn + [Key]: Accesses secondary functions printed on keycaps (e.g., F1-F12, arrow keys, Home, End, Page Up/Down).
- Fn + I, J, K, L: May function as arrow keys depending on the active mode.
5.2 RGB Lighting Control
The YK61 offers various RGB lighting effects. These can be controlled directly on the keyboard using Fn key combinations or through the dedicated software.
Common onboard controls (refer to your quick reference card for exact combinations):
- Fn + \|: Cycle through lighting effects.
- Fn + [Arrow Keys]: Adjust brightness or speed of effects.
- Fn + [Specific Keys]: Change lighting colors or modes.
For advanced customization, use the YOUSUOMASTER software to:
- Select from 19 preset RGB lighting effects.
- Customize individual key colors.
- Create custom lighting profiles.
- Enable music rhythm backlight synchronization.
5.3 Programmable Software Functions
The YOUSUOMASTER software provides extensive control over your keyboard:
- Key Mapping: Reassign any key to a different function.
- Macro Definitions: Record and assign complex sequences of key presses to a single key.
- Actuation Customization: Adjust the actuation point of each magnetic switch from 0.1mm to 4.0mm with 0.1mm sensitivity.
- Rapid Trigger Mode Settings: Enable/disable Rapid Trigger and fine-tune its sensitivity.
- Profile Management: Save and switch between multiple custom profiles for different games or applications.
6. Maintenance
6.1 Cleaning the Keyboard
To maintain optimal performance and appearance:
- Disconnect the keyboard from your computer before cleaning.
- Use a soft brush or compressed air to remove dust and debris from between the keycaps.
- For keycap cleaning, use a slightly damp cloth with mild soap and water. Ensure keycaps are completely dry before reattaching.
- Avoid using harsh chemicals or abrasive materials.
6.2 Hot-Swapping Switches and Keycaps
The YK61 supports hot-swappable magnetic switches and standard keycaps.
- Removing Keycaps: Use the included keycap puller. Gently hook the puller onto the keycap and pull straight up.
- Removing Switches: Use a switch puller (not included, but often comes with replacement switches). Carefully grip the switch from the top and bottom clips and pull straight up.
- Installing Switches: Align the new magnetic switch with the socket on the PCB. Press down gently until it clicks into place. Ensure the pins are not bent.
- Installing Keycaps: Align the keycap with the switch stem and press down firmly until it is seated.

7. Troubleshooting
7.1 Keyboard Not Responding
- Ensure the USB-C cable is securely connected to both the keyboard and your computer.
- Try connecting the keyboard to a different USB port on your computer.
- Test the keyboard on another computer to rule out a system-specific issue.
- Restart your computer.
7.2 RGB Lighting Not Working or Incorrect
- Check onboard lighting controls (Fn key combinations) to ensure lighting is not turned off or set to a very dim level.
- Ensure the YOUSUOMASTER software is running and the correct profile is selected.
- Update the keyboard firmware via the YOUSUOMASTER software if available.
7.3 Keys Not Registering or Double-Typing
- This could indicate a faulty switch. Since the switches are hot-swappable, try replacing the problematic switch.
- Ensure the switch is fully seated in its socket.
- Check the actuation point settings in the YOUSUOMASTER software; a very low actuation point might cause unintended presses.
7.4 Software Not Detecting Keyboard
- Ensure the keyboard is connected via a wired USB-C connection. The software only supports wired mode.
- Verify that you have downloaded the correct YK61 driver software from yousuomaster.com.
- Temporarily disable any antivirus or firewall software that might be blocking the application.
- Run the software as an administrator.
