Keywords: Shortcut; Keyboard; Mouse; KVM; Troubleshooting; Hotkey

Applicable product model: All of the KVM switches,

📌If the hotkeys are not functioning after connecting the keyboard and mouse to the KVM switch, please follow these troubleshooting steps:

Detect whether the transparent transmission function is turned off.

For KVM switches with mode indicators, check if the "Mode Indicator" on the front panel is illuminated. If it is lit, the keyboard and mouse pass-through mode is enabled. If the light is not on, you can try to use the following key combination to enable keyboard-mouse passthrough mode: [Scroll Lock] --> [Scroll Lock] --> F2 or [Right-Ctrl] --> [Right-Ctrl] - -> F2.

For KVM switches without mode indicators, you can try the following hotkey combination: [Scroll Lock] --> [Scroll Lock] --> F3 or [Right Ctrl] --> [Right Ctrl] --> F3. If you hear two beeps from the buzzer, it indicates that the pass-through mode is enabled. If you hear one beep, it means the pass-through mode is disabled.
If your KVM switch doesn't have a mode indicator or beep sounds even after using the hotkey, there's no need to worry. This indicates that you may have the latest version of the KVM switch, which has a built-in keyboard and mouse pass-through mode. In this case, the hotkey detection method is not applicable. The keyboard and mouse pass-through mode is always enabled by default on your KVM switch.
1. For professional brands such as Logitech, Razer, and others that have driver software installed for their keyboards and mice, please ensure you save your settings and exit the keyboard and mouse driver software before proceeding.
1. Confirm that your keyboard is connected to the dedicated ports for the keyboard and mouse on the KVM switch. The KVM switch is designed to support the hotkey function only on these dedicated ports. If your keyboard is connected to a USB 2.0 port on the KVM switch, the hotkey function will not work.
If your keyboard is connected to the correct port, please proceed to the next step.

Verify if the hotkey trigger key has been changed. The KVM switch is configured with two hotkey trigger keys: Scroll Lock and Right-Ctrl. You can choose the one that suits your preference. Try using [Right-Ctrl] -> [Right-Ctrl] -> 1/2/3/4 to switch the input source. If it works, you can keep Right-Ctrl as the hotkey trigger or use [Right-Ctrl] -> [Right-Ctrl] -> F1 to switch it back to Scroll Lock.

If the above method doesn't resolve the issue, check if your keyboard has an Fn button. If it does, try using [Fn] -> [Scroll Lock] -> [Scroll Lock] -> 1/2/3/4 to switch the input source.

6. Consider turning off the control software that came with your keyboard and mouse.

Some keyboards and mice have special software for customization and setup, but this software can sometimes create compatibility conflicts with KVM switches. After saving any necessary settings, try closing the control software to see if the problem is resolved.
