Maintenance

To ensure the longevity and optimal performance of your TESmart KVM switch, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the exterior of the device. Avoid using liquid cleaners or abrasive materials, which can damage the surface or internal components.

• Firmware Updates: Check the TESmart official website periodically for any available firmware updates, which can improve performance and add new features.

Troubleshooting

If you encounter issues with your KVM switch, refer to the following common troubleshooting steps:

• No Display/Flickering Screen:
  • Ensure all HDMI and DisplayPort cables are securely connected to both the KVM and your computers/monitors.
  • Verify that the correct input source is selected on your monitors.
