The Launcher provides users with a keyboard key testing tool, which can quickly help users check keyboard sensitivity, identify faulty keys, and deliver a better user experience.

The specific steps are as follows:

1. Use the latest version of Chrome/Opera/Edge browser to click the link and open the launcher.

2. After establishing a physical connection using our dedicated connecting cable or 2.4 GHz receiver, click the ‘Connect’ button on the Launcher and select the device you need to configure to connect to it.

   Notice: Some product models only support a wired connection.

3. Select “Key Test” from the function bar on the left side.

   

4. Now you can click and test any keyboard key. After clicking a key, the corresponding button on the virtual keyboard in Launcher will turn red, and a number will be displayed in the upper right corner of the key —— indicating the effective click count detected for that key.

   

     We also provide users with key detection sounds and matrix testing.

   1. Key detection sounds: When the switch is on, key testing will have sound feedback, and you can choose your preferred sound.

   2. Matrix testing: The matrix testing of the keyboard works like assigning a unique “row + column” coordinate to each key. By scanning these coordinates, it quickly locates the pressed key and identifies its function.
