7. Maintenance

• Keep the KVM switch in a dry, well-ventilated area.
• Avoid exposing the device to extreme temperatures or humidity.
• Clean the device with a soft, dry cloth. Do not use liquid cleaners or aerosols.
• Ensure cables are securely connected and not under strain.

8. Troubleshooting

If you encounter issues with your KVM switch, please refer to the following common solutions:

• No Display/Signal:
  • Ensure all HDMI cables are securely connected to both the KVM switch and the computers/monitor.
  • Verify that the correct input source is selected on your monitor.
  • Try restarting the connected computers.
  • Check if the KVM switch is receiving power via the USB connections from the computers.
• Keyboard/Mouse Not Responding:
  • Ensure the keyboard and mouse are connected to the dedicated USB ports on the KVM switch, not the general USB HUB ports, especially for hotkey functionality.
  • Try reconnecting the keyboard and mouse.
  • Test the keyboard and mouse directly with a computer to confirm they are functional.
  • Some specific gaming keyboards/mice with advanced features may have compatibility issues. Try a standard keyboard/mouse if problems persist.
• Hotkey Switching Not Working:
  • As noted in the operating instructions, the keyboard and mouse must be connected to the specific USB interfaces of the KVM switch box for hotkey functionality to work. Connecting them to the other USB HUB ports will prevent hotkey switching.
  • Ensure the hotkey sequence is performed correctly (e.g., double-click Scroll Lock, then press number).
• Computer Crash or Stuck Peripherals:
  • The KVM switch uses a high-quality chip designed to reduce such occurrences. Ensure all connections are stable.
  • If issues persist, try connecting peripherals directly to the computer to isolate the problem.
• Mac Compatibility:
  • Please note that this KVM switch may have poor compatibility with Mac systems. Functionality may be limited or inconsistent.
