The MX108 keyboard shares its receiver with the mouse. You can locate the 2.4G receiver at the bottom of the mouse, as shown in the image below.

TGL, or Toggle Key, transforms a key into a toggle switch. When you press this switch, you can activate one of two scenarios: either continuously hold down the key/function, or trigger the key/function multiple times at a set frequency (similar to high-frequency tapping).

To set up TGL:

  1. Select the key you wish to program.
  2. In the “Combination” and “Macro” fields on the left, define the key combinations or macros you want to activate when pressing or holding down the key.
  3. Press “confirm” to complete the setup.

You can click on the little triangle to toggle Hold and Automatic keystrokes.

Mod-Tap is a feature designed to enhance convenience for both gaming and productivity tasks. With Mod-Tap, a single keypress can trigger two functions: holding down the key for one action and pressing the key for another. It allows users to create dedicated or dual-functional keys based on their keypress behavior. This feature is particularly useful for compact keyboards, enabling efficient key combinations such as long-pressing the ESC key to output ~ or accessing the task manager with a specific key combination (Alt+Ctrl+Delete).

To set up Mod-Tap:

1. Select the key you want to set and the “Hold and Press” option box will light up.

2. In the “Combination” and “Macro” fields on the left, define the key combinations or macros you want to activate when holding down the key.

3. Click “Confirm” to apply the settings for the Hold key. This allows you to activate Task Manager directly by holding F1.

4. You can set up Tap keys in a similar manner or leave them unchanged.

5. Adjust the keypress time using the slider at the bottom to customize the time required to trigger the “hold down” key definition (default is 200ms).

MonsGeek offers four distinct stroke settings, each tailored to different preferences and applications:

Comfort Mode: This mode closely mirrors traditional mechanical switches, featuring a 2mm actuation point and a 2mm reset point. It’s ideal for standard typing and work tasks.

Sensitive Mode: In this mode, the actuation point is reduced to 0.5mm while the reset point remains at 2mm. It’s designed for users who require fast key triggers and responses.

Game Mode: Game Mode unleashes the power of Rapid Trigger (RT). Here, the fixed actuation and reset points are eliminated, allowing switches to respond instantly to even the slightest pressure changes. It’s perfect for gamers seeking utmost responsiveness.

Customize Mode: In Customize Mode, you can modify the behavior of any key to suit your preferences. This mode offers a high degree of personalization, allowing you to tailor the keyboard to your specific needs and workflow.

To adjust the actuation and reset points:

Use the left slider to adjust the actuation point (Press) and the right slider to adjust the reset point (Up).

Enable “All keys” to apply your settings to all keys, or select specific keys for individual adjustments.

Due to environmental factors and potential interference, there might be instances of input interruption when keys are fully bottomed out. To address this, we’ve introduced a dead zone setting, which designates a range at the bottom of each key that will not be triggered, ensuring functionality upon release.

Turn on “Non-stop Rapid Trigger” to activate the RT function (in this mode, the reset point is replaced by the release distance and cannot be adjusted).

With RT enabled, switches respond to even slight pressure changes within the actuation range. You can set the press distance to trigger the key and the release distance to reset it in the additional menu that appears after RT activation.

Note: While a 0.1mm option is available, to prevent accidental triggers or loss of contact due to slight movements, it’s advisable to set press/release distances no lower than 0.3mm as shown in the illustration above. If you experience frequent loss of contact, increase the release distance. If you encounter accidental triggers, increase the press distance.

In conclusion, unless you have specific requirements, Game Mode should suffice for most gaming scenarios, while Comfort Mode is highly recommended for office work and typing tasks.

75% MonsGeek HE keyboards come with 2 normal layers and 2 Fn layers. You can adjust these layers using either the MonsGeek Driver or through hotkeys.

1. Use Fn+F9/F10 to switch to normal layer 1/2 respectively. Hold Fn and press right Alt to switch below Fn layer 1 and Fn layer 2.

2. Alternatively, you can directly modify the normal layers in the Driver Main-Remap Page, and adjust the Fn layers in the Fnsetting Page.

When you receive your MonsGeek HE keyboard, it’s essential to upgrade the firmware and calibrate the keyboard. Please follow the steps below:

1. Download the Latest Driver and Update Firmware:

​Ensure that your keyboard is running on the latest firmware version to experience its full potential. Outdated firmware, especially in Rapid Trigger (RT) modes, may cause typing issues. Download the latest MonsGeek Driver from our official download page and upgrade your firmware. MonsGeek downloadYou can find the Upgrade button on the About page in the Driver. Please don’t move the keyboard and mouse during the update.

​2. Calibration:

Magnetic switch keyboards aim to provide a seamless typing experience. However, Hall sensors are sensitive to temperature variations, resulting in potentially significant changes to the magnetic field of the keyboard during transportation, influenced by temperature and environmental shifts (imagine shipping from California to Maine).

During this calibration, users should apply regular, moderate force while pressing the keys, and make sure to bottom out. However, please avoid pressing too hard during calibration, as excessive bottom-out force might lead to unresponsive keys at a large actuation distance (say, 3.5~3.8mm). Follow the steps below to calibrate the keyboard:

a. ​​You can find the calibration button on the About page in MonsGeek Driver. Follow the steps on the screen to complete the calibration.

b. Press confirm to start.

c. During calibration, press each key to its lowest point with a similar force. Ensure that every key is pressed and released during this step. Press the “Confirm” button after completing this calibration.

d. If any keys still do not function correctly, it indicates that they may not have been pressed completely during calibration. In such cases, repeat the calibration process to ensure that all keys are functioning as expected.

MonsGeek Magnetic Switches keyboards are designed to support downward-facing S-pole magnetic switches. If you intend to use switches from other brands, please be aware that some may have additional legs that need to be cut. It’s crucial to consider the structure of the magnet; for instance, a vertical magnet might not be compatible with a PCB that supports only horizontal magnets.

Moreover, Some MonsGeek magnetic switch keyboards also offer support for 3-pin mechanical switches. However, after replacing with mechanical switches, it is essential to calibrate the maximum travel. You can find this calibration option on the “About” page in the driver software. Please find more details here: When and How to Calibrate MonsGeek Magnetic Switch Keyboard
