Operating Instructions

Switching Between Computers

The TESmart KVM Switch offers several convenient methods for switching between connected computers:

• Front Panel Buttons: Press the 'Select' buttons on the front panel of the KVM switch to cycle through the connected inputs (1-4).
• Hotkey Switching: Use keyboard hotkeys for quick switching. Typically, this involves pressing the 'Scroll Lock' key twice, followed by 'PgUp', 'PgDown', or the number corresponding to the input (1, 2, 3, or 4). Note that hotkeys usually work with the top row numbers, not the number pad.
• IR Remote Control: Use the included IR remote control to select the desired input. Ensure the remote has AAA batteries installed (not included).
• Mouse Wheel Switching: Some configurations may allow switching by double-clicking the middle mouse button (scroll wheel).

Maintenance

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

• Cleaning: Regularly wipe the exterior of the KVM switch with a soft, dry cloth to remove dust and debris. Avoid using liquid cleaners or abrasive materials.
• Ventilation: Ensure the KVM switch is placed in a well-ventilated area to prevent overheating. Do not block any ventilation openings.
• Cable Management: Keep cables organized and untangled to prevent strain on ports and ensure proper airflow.
• Storage: If storing the device for an extended period, disconnect all cables and store it in a cool, dry place away from direct sunlight and extreme temperatures.

Troubleshooting

If you encounter issues with your TESmart KVM Switch, refer to the following common problems and their solutions:

• No Display or Black/Green Screens After Switching:
  • Ensure all HDMI and USB cables are securely connected to both the KVM switch and the computers/monitor.
  • Try using a different HDMI output port on your computer or a different converter/adapter combination if you are using one (e.g., USB-C to HDMI adapter).
  • Power cycle the KVM switch and the connected computers.
• Keyboard Skipping Characters or Not Registering Inputs:
  • Ensure your keyboard is plugged into the dedicated keyboard USB port on the KVM switch.
  • If using a mechanical keyboard or one with high power requirements, try connecting it through a powered external USB hub before plugging it into the KVM switch.
  • Verify that the keyboard is not a wireless Bluetooth model, as these are not supported.
• USB Pass-Through Functionality Issues (e.g., USB headset not detected):
  • If a peripheral connected to a USB port on your keyboard (pass-through) is not detected, try plugging the peripheral directly into one of the available USB 3.0 ports on the KVM switch itself.
• Switching Delay:
  • While the KVM switch aims for seamless switching, a slight delay (approximately 3 seconds) may occur during the transition between inputs. This is normal operation.
• Remote Control Not Working:
  • Ensure AAA batteries are correctly inserted into the IR remote control.
  • Point the remote directly at the IR receiver on the KVM switch.
  • Check for any obstructions between the remote and the KVM switch.
