Internal Structure and Components:
The AK820 MAX HE is engineered with a robust internal structure for durability and enhanced typing feel.
- Gasket-Mounted Design: This design incorporates soft gasket material between the plate and the PCB, isolating them from the case. This provides a flexible, cushioned typing experience and reduces vibrations.
- Sound-Dampening Layers: Multiple layers of Poron foam, EVA foam, and a silicone case pad are integrated to absorb sound and improve the acoustic profile of keystrokes, resulting in a "creamy" sound.
- PC Plate: A polycarbonate (PC) plate is used for its flexibility, contributing to the soft typing feel and consistent switch performance.
- PBT Keycaps: The keyboard comes with durable PBT (Polybutylene Terephthalate) keycaps, known for their resistance to shine and wear over time, ensuring legends remain clear. They feature a Cherry profile for ergonomic comfort.

Operating Instructions
1. Hall Effect Magnetic Switches:
The AK820 MAX HE utilizes Hall Effect magnetic switches, which detect key presses based on magnetic field changes rather than physical contact. This allows for highly precise and customizable actuation.
- Operating Force: 50±5gf
- Total Travel: 4.0±0.3mm
- Initial Magnetic Flux: 60±20Gs
- Bottom-out Magnetic Flux: 700±100Gs
- Action Travel: Freely Setting (Adjustable Actuation)
- Life Span: 100 Million Times

2. Adjustable Actuation Point:
The Hall Effect magnetic switches allow you to set the actuation point for each key from 0.2 mm to 2.5 mm. This feature is crucial for competitive gaming, allowing for faster key presses or more deliberate inputs.
- Use the AJAZZ Driver software to precisely adjust the actuation depth for individual keys or groups of keys.
- A lower actuation point (e.g., 0.2 mm) means the key registers with minimal travel, ideal for rapid actions.
- A higher actuation point (e.g., 2.5 mm) requires more travel, reducing accidental presses.

3. Advanced Key Modes (Software Dependent):
The AK820 MAX HE supports advanced key modes via the AJAZZ Driver software:
- Dynamic Key Switching (DKS): Allows different actions based on key travel, tap/hold, or release distance. For example, a light press could be one action, and a full press another.
- Magnetic Tactile (MT): Provides a tactile bump sensation through software, enhancing feedback without physical changes to the switch.
- Trigger-Lock (TGL): Enables a key to remain activated until a specific condition is met or another key is pressed, useful for continuous actions.
- SOCD (Simultaneous Opposite Cardinal Directions): Helps resolve conflicting directional inputs, common in fighting games.
4. TFT Display Screen and Knob:
The 0.85-inch TFT screen provides useful information and customization options, controlled by the multifunctional knob.
- Default Display: Shows time, battery level, and current connectivity mode.
- Customization: Use the AJAZZ Driver software to upload custom GIFs or images to the screen.
- Knob Functionality:
- Rotate the knob to adjust system volume.
- Press the knob to mute/unmute audio.
- Press FN + Knob: Enter the setting page on the screen. Rotate the knob to navigate options, press to confirm.
- Press FN + B: Switch between animation/GIF display and the main information page on the screen.

5. RGB Backlighting:
The keyboard features 16.8 million color RGB backlighting with various effects.
- Press FN + \: Toggle between different backlight effects.
- Press FN + →: Toggle between different backlight colors.
- Press FN + X: Turn the backlights On/Off.
- Further customization of lighting effects and colors is available through the AJAZZ Driver software.

6. Hot-Swapping Switches:
The AK820 MAX HE features a hot-swappable PCB, allowing you to easily change magnetic switches without soldering. This is only compatible with other magnetic switches (e.g., Kailh, Gateron magnetic switches).
- Use the provided keycap puller to remove the keycap.
- Use the switch puller to gently remove the magnetic switch from the PCB.
- Align the pins of the new magnetic switch with the sockets on the PCB and press firmly until it clicks into place.
- Replace the keycap.

7. Operating System Switch:
A physical switch on the rear of the keyboard allows you to toggle between Windows (Win) and Mac operating system layouts, ensuring proper key mapping.
Maintenance
- General Cleaning: Regularly wipe the keyboard surface with a soft, dry, lint-free cloth. For deeper cleaning, use a can of compressed air to remove dust and debris from between keycaps.
- Keycap Cleaning: Keycaps can be removed for thorough cleaning. Use mild soap and water, then ensure they are completely dry before reattaching.
- Switch Care: While magnetic switches are durable, avoid exposing them to excessive moisture or extreme temperatures. If switches feel sluggish, ensure no debris is lodged around the stem.
- Battery Care: To prolong battery life, avoid fully discharging the keyboard frequently. Charge the keyboard using the provided USB-C cable when the battery indicator on the TFT screen shows low power.
Troubleshooting
Keyboard Not Responding:
- Wired Mode: Ensure the USB-C cable is securely connected to both the keyboard and the computer. Try a different USB port or cable.
- 2.4GHz Wireless: Verify the dongle is properly inserted and the keyboard is switched to 2.4G mode. Press FN + R to re-pair. Check battery level.
