Operating Instructions
Switching Between Computers
The CKL KVM Switch offers multiple methods for switching between connected computers:
- Push Button Switching: Press the 'SELECT' button on the front panel of the KVM switch to cycle between PC1 and PC2.
- Keyboard Hotkey Switching: Ensure the 'Hot Key ON/OFF' switch on the front panel is in the 'ON' position. To switch, quickly press the Right Control (Ctrl) key twice, then the port number (1 for PC1, 2 for PC2), and finally press Enter.
- Mouse Switching: Double-click the scroll wheel of your mouse to switch between computers.
- Wired Remote Switching: Press the button on the wired remote control to switch between computers.

The KVM switch supports various display configurations for your dual monitors:
- Extended Display: Each monitor displays a different part of the desktop, extending your workspace.
- Mirrored Display: Both monitors display the same content.
- Splicing Wall: Allows for advanced display configurations, often used for video walls.

Maintenance
To ensure the longevity and optimal performance of your KVM switch, follow these general maintenance guidelines:
- Keep the device in a cool, dry place away from direct sunlight and excessive heat.
- Avoid exposing the device to liquids or excessive moisture.
- Clean the exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Ensure proper ventilation around the unit to prevent overheating.
- Regularly check cable connections to ensure they are secure.
Troubleshooting
If you encounter issues with your CKL KVM Switch, please refer to the following common problems and solutions:
- No Display or Intermittent Display:
- Verify all HDMI and USB 3.0 cables are securely connected between the computers, KVM, and monitors.
- Ensure the correct PC input is selected on the KVM switch (check indicator LEDs).
- Confirm that your monitor resolution and refresh rate are supported by the KVM switch (up to 4K@60Hz for HDMI).
- Try power cycling the KVM switch and then the connected computers and monitors.
- Keyboard or Mouse Not Working:
- Ensure the keyboard and mouse are plugged into the dedicated keyboard and mouse ports on the front panel. For wireless sets, try plugging the unifying dongle into one of the USB 3.0 HUB ports if issues persist with the dedicated ports.
- If using special keyboards or mice, try disabling the hotkey function via the 'Hot Key ON/OFF' switch.
- Power cycle the KVM switch.
- Audio Issues:
- Ensure HDMI audio is set as the default output device in your computer's sound settings.
- Check the connection of your speakers or headphones to the KVM's audio output jack.
- Windows Rearranging/Resizing After Switching:
This behavior can occur with some KVM switches as the monitors are virtually disconnected and reconnected during the switch. This is often a characteristic of the operating system's display management rather than a KVM fault. Some operating systems or third-party utilities may offer solutions to manage window positions.
- KVM Needs Frequent Power Cycling:
If peripherals stop responding or the switch becomes unresponsive, power cycling the KVM (turning it off and on) can often resolve the issue. Ensure stable power supply to the unit.
