6. Maintenance

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

• Keep the device in a cool, dry place, away from direct sunlight, high temperatures, and humidity.
• Clean the unit with a soft, dry cloth. Do not use liquid cleaners or aerosol sprays.
• Avoid blocking the ventilation holes on the sides of the unit to prevent overheating.
• Do not attempt to disassemble or modify the device, as this will void the warranty and may cause damage.

7. Troubleshooting

If you encounter issues with your Fosmon HDMI Switch, please refer to the following common problems and their solutions:

7.1 Display is Flickering or No Signal

• Check HDMI Cables: Ensure all HDMI cables are securely connected to both the switch and your devices/display.
• Cable Quality and Length: For 8K@60Hz or 4K@120Hz, use high-quality HDMI 2.1 certified cables. Keep individual HDMI cable lengths under 3 meters (9.8 feet) for optimal signal integrity.
• Power Supply: Verify the switch is properly powered via the USB-C cable and a reliable 5V USB adapter.
• Resolution Compatibility: Ensure your display and source devices support the selected resolution and refresh rate.

7.2 Remote Control Not Working

• Check Batteries: Ensure 2 AAA batteries are correctly inserted into the remote control. Replace if necessary.
• Line of Sight: Make sure there is a clear line of sight between the remote and the IR receiver on the switch.
• Distance and Angle: The remote should be within 26 feet (8 meters) of the switch and at an angle no more than 45 degrees from the receiver.
• IR Indicator: Confirm the IR indicator light on the switch is ON. If not, press the "IR" button on the remote to activate it.

7.3 CEC (Consumer Electronics Control) Function Not Working

• Input 1 Only: The CEC function is only supported on INPUT 1 of the Fosmon HDMI Switch. Ensure your CEC-enabled device is connected to INPUT 1.
• Original Remote: Only the original remote control provided with the switch can be used to switch ports via the CEC function. Third-party remotes are not supported for this feature.
• Device/TV CEC Settings: Confirm that CEC is enabled on both your source device (e.g., PS5, Xbox, Apple TV) and your television/display.
